421bd04a95 boards/nucleo-l073rz: Add USB device support and a CDC/ACM configuration.
The STM32L073RZ provides a full speed USB device controller, but the
Nucleo-L073RZ board support did not enable it and no configuration
exercised it.

Add the pieces required to run USB device mode on this board:

- Add the USB device pin definitions to the STM32L0 pin map.
- Provide board level pull-up control using the embedded DP pull-up in
  USB_BCDR, and register the CDC/ACM class at boot when it is selected.
- Add a usb-cdc configuration that presents an NSH console on USART2 and
  a CDC/ACM serial device on USB.

The 48MHz clock for the controller is supplied by HSI48 trimmed from the
USB start of frame packet, which is the crystal-less USB configuration
already described by this board's board.h.

vrefint_enable() sets SYSCFG_CFGR3_ENBUFVREFINTHSI48 in its local copy
of the register value but never writes that value back to the hardware.
The VREFINT reference for the HSI48 scaler is therefore never enabled.

Only the earlier ENVREFINT update reaches the register, so VREFINT
itself is enabled while the HSI48 reference is not.  HSI48 then runs
without its voltage reference and the 48MHz clock is not accurate enough
to be used by the USB device controller.

Write the register after applying the HSI48 reference bit.

a266398a4f arm/stm32: Enable the CRS frequency error counter with autotrim.
stm32_enable_hsi48() set CRS_CR_AUTOTRIMEN but left CRS_CR_CEN clear.
AUTOTRIMEN only instructs the hardware to apply corrections derived from
the frequency error counter; the counter itself is enabled by CEN.  With
CEN clear no error measurement is ever produced and the HSI48 TRIM value
stays at its reset default, so the oscillator is never disciplined to the
synchronisation source.

Set both bits, matching the value the STM32 ROM bootloader programs when
it runs its own crystal-less USB stack (CRS_CR = 0x1a60, i.e.
CEN | AUTOTRIMEN with a trimmed TRIM field).

This file is shared by the M0 STM32 parts (F0, G0, C0, L0); all of them
require CEN for automatic trimming to function.

16e3c8c6de stm32l0: Enable SYSCFG clock when VREFINT is enabled.
The SYSCFG peripheral clock was gated on CONFIG_STM32_SYSCFG, but that
symbol is not defined by the STM32L0 Kconfig (only stm32h7 declares it),
so RCC_APB2ENR_SYSCFGEN was never set on this chip.

With SYSCFG unclocked every write performed by vrefint_enable() is
discarded and SYSCFG_CFGR3 reads back as 0x00000000.  VREFINT and, in
particular, the ENBUFVREFINTHSI48 reference for the HSI48 oscillator are
therefore never enabled.  HSI48 still reports HSI48RDY, but it runs
without its voltage reference and the 48MHz clock supplied to the USB
device controller is unusable: the controller cannot sample the bus,
never latches a reset condition in USB_ISTR, and never raises its
interrupt.  The result is a USB device that is configured correctly in
every visible register yet never enumerates.

VREFINT is configured exclusively through SYSCFG_CFGR3, so enable the
SYSCFG clock whenever CONFIG_STM32_VREFINT is selected.

Observed on NUCLEO-L073RZ (STM32L073RZ):

  before: SYSCFG_CFGR3 = 0x00000000, no enumeration
  after:  SYSCFG_CFGR3 non-zero, device enumerates as CDC/ACM

561da42812 stm32f0/l0: Gate the CRS clock on STM32_USE_HSI48.
The clock recovery system peripheral clock was enabled only when
CONFIG_STM32_CRS was selected.  The CRS is required by any board that
uses HSI48 as the 48MHz clock source, because HSI48 must be trimmed from
an external synchronisation event to stay within the tolerance demanded
by USB full speed operation.

STM32_USE_HSI48 is the condition under which the remaining HSI48 and CRS
setup is compiled in, see stm32_enable_hsi48(), so accept that condition
here as well.  Without the peripheral clock the CRS registers are
inaccessible and automatic trimming silently does nothing.

CONFIG_STM32_CRS is retained so that boards selecting the CRS directly
are unaffected.

d70725e4e0 arm/stm32: Fix the USB reset sequence in arm_usbinitialize().
The code that claimed to "enable clocking to the USB peripheral" cleared
RCC_APB1ENR_USBEN inside RCC_APB1RSTR.  That is both the wrong register
and the wrong bit: USBEN belongs to RCC_APB1ENR, while APB1RSTR holds
RCC_APB1RSTR_USBRST.  The peripheral clock is enabled by the RCC setup
performed at boot, so the write had no useful effect and merely cleared
an unrelated reset bit.

Issue a proper reset pulse on RCC_APB1RSTR_USBRST instead, so the
controller starts from a known state.

On STM32L0 the D+/D- lines are connected to the USB transceiver
automatically once the peripheral is enabled and there is no alternate
function to select, so skip the GPIO configuration on that chip.  The
board GPIO_USB_DM/GPIO_USB_DP definitions do not exist there.

fc05091e18 arm/stm32: Enable and acknowledge USB error interrupts on M0 parts.
The initial interrupt mask enabled only reset, suspend and correct
transfer.  Error conditions reported by the controller, USB_ISTR_ERR and
USB_ISTR_PMAOVRN, were neither enabled nor acknowledged.

Because the status bits are never cleared, an error condition latched in
USB_ISTR remains set and is re-evaluated on every subsequent interrupt,
which makes the reported status misleading when debugging transfer
problems.

Add ERRM and PMAOVRN to the initial mask and clear the corresponding
status bits when they are seen.

432d21a116 arm/stm32: Route EP0 completions to the EP0 handler on M0 parts.
The correct transfer loop in stm32_usb_interrupt() dispatched every
completion to stm32_epdone(), including those for endpoint 0.

stm32_epdone() implements the generic bulk/interrupt endpoint completion
path.  It does not decode the SETUP stage, does not maintain the EP0
state machine, and does not apply the EP0 specific RX/TX status rules.
Control transfers therefore never completed correctly and the device
could not be enumerated.

Dispatch endpoint 0 to stm32_ep0done(), which is the control endpoint
handler and is already used for the same purpose by the low priority
transfer path in stm32_lptransfer().

a271b641a5 arm/stm32: Fix USB packet memory addressing on M0 parts.
The packet memory area (PMA) accessors in the M0 USB device driver were
carried over from the STM32F1 implementation, where the PMA is seen by
the CPU as 16-bit values placed on 32-bit boundaries.  On the STM32F0,
STM32L0 and other M0 parts the PMA is a linear 16-bit memory, so the
F1 scaling is wrong:

- STM32_USB_BTABLE_RADDR() shifted the computed buffer descriptor offset
  left by one, addressing every second descriptor entry.
- The buffer descriptor accessors declared the descriptor entries as
  uint32_t and accessed them 32 bits at a time, so each write clobbered
  the adjacent entry.
- stm32_copytopma() and stm32_copyfrompma() scaled the PMA offset by two
  when computing the packet buffer address.

The result is that endpoint buffer descriptors and packet data are
written to the wrong offsets in packet memory, and no transfer completes
correctly.

Drop the F1 scaling and use 16-bit accesses throughout.  Note that the
sibling stm32_usbfs.h defines STM32_USB_BTABLE_RADDR() without the shift
already, so this brings the M0 header in line with it.

6ccb459e1a arch/tricore: drop iLLD dependency in hwdebug
Remove the dependency on the iLLD SFR headers (IfxCpu_bf.h and
IfxCbs_reg.h) and the iLLD intrinsics (__mfcr/__mtcr) from the
hardware debug monitor implementation.

The debug CSFR numbers, trigger-event register (TR0..TR7) addresses,
TREVT bit-field offsets and the CBS_OEC register address are now
defined locally with a TC_ prefix, so the file no longer leaks the
iLLD CPU_* namespace (which is still pulled in transitively through
arch/irq.h).  Register accesses use the tricore_mfcr/tricore_mtcr
macros, and the DBGTCR/DBGCFG/DBGACT bit-field unions are replaced
with explicit shifts.

This is a pure de-iLLD refactor with no behavior change, verified on
a TC4x7 EVB: the board boots to NuttShell and breakpoints trigger
identically before and after the change.

78dfefa4cc boards/risc-v/eic7700x: Adopt the common board layout.
The port had one board directory holding one board, with everything in it
whether it described the SoC or the PCB.  A second EIC7700X board follows,
so this adopts the common-plus-board layout NuttX provides, as mpfs uses.

boards/risc-v/eic7700x/common holds what is true of the SoC: the boot path
that mounts the RAM disk and /proc before calling the board's own bring
up, the linker script, the start up scripts and the image builder.
ARCH_CHIP_EIC7700X selects ARCH_BOARD_COMMON, so the symlinks the build
makes always point at code that compiles.

The board directory keeps what is a fact about the PCB: its own board.h
and board_memorymap.h, since the include fallback is all or nothing, a
bring up that owns the order its devices register in, and a board_config.h
declaring what that bring up may call.

The image builder moves to common/tools and derives its output name from
the configuration.  It computes the padding between the kernel and the RAM
disk from _ebss rather than assuming 64 KiB, which fails once BSS grows
past it: the disk lands below _ebss and the BSS clear zeroes it before
anything searches for it.

The StarPro64 configuration gains what the port now needs: four harts,
960 MiB of RAM, a larger task stack, a backtrace on assert, the system log
in RAM for dmesg, and ELF applications, for which ARCH_CHIP_EIC7700X now
selects ARCH_HAVE_ELF_EXECUTABLE.

board.h loses its LED definitions.  CONFIG_ARCH_LEDS is not set, nothing
implements board_autoled_on(), and the indices they gave named no LED.

The documentation pages gain the tags the template asks for.

c60257bcc2 arch/risc-v/eic7700x: Correct the kernel memory map.
Three faults in how the kernel maps itself.

The page pool covered the RAM disk, which the boot loader appends above
the kernel, so the BSS clear destroyed it before anything searched for it.
The pool now covers only pgram, and the RAM disk is mapped on its own
account.

The kernel data region is mapped with 2 MiB pages rather than 4 KiB ones.
Everything in it carries the same permissions, so the finer granularity
bought nothing while costing one L3 slab per 2 MiB from a pool of two.

The linker script and Kconfig describe the page pool separately and both
descriptions are used, so they now agree.  When they disagree, pages
outside the smaller of the two get a virtual address of zero and are
written through, which on this SoC lands on identity mapped low memory
rather than faulting.

fc488eef01 arch/risc-v/eic7700x: Enter on any hart and run all four.
The port ran on whichever hart the firmware handed over on, with a single
idle stack.  The firmware does not pick the same hart every boot, so
nothing may assume one.

The hart that arrives first records which it was, indexes its idle stack
by its own ID, and restarts on hart 0; NuttX runs CPU0 there because that
is the only hart riscv_set_inital_sp() gives a whole idle stack to.  The
first hart in owns the one time setup, and that guard lives in .data
because it is read before the BSS is cleared.

CONFIG_SMP_NCPUS below four is refused in chip.h: the hart the firmware
picked would have no slot and would stop in __start before it could
restart, which fails on some resets and not others.

Secondary harts are released through the common SBI helper rather than a
private copy of the same call.

2ef5db01f0 arch/arm/stm32: use common SYSTICK_HCLKd8 symbol
The SysTick timer logic of stm32h5, stm32h7, stm32l4, stm32l5, stm32u5
and stm32wl5 tests a family specific SYSTICK_HCLKd8 symbol, while
common/stm32 and stm32wb already test CONFIG_STM32_SYSTICK_HCLKd8.  Use
the common name everywhere.

No Kconfig defines the symbol and the timer logic undefines it
unconditionally, so this does not change the generated code.

f15d609069 arch/arm/stm32h5: use common Kconfig symbols
The headers test CONFIG_STM32H5_* names that no Kconfig defines (the
STM32H5xXXX families, FLASHEN, OTFDEC1EN, DCACHE, STM32H2X/H3X/H7X), so
those branches are dead code.  Use the common CONFIG_STM32_* symbols.

Fix what this exposes: derive the SRAM2/SRAM3 bases from the family SRAM
sizes, since the boot ECC init would otherwise write past the end of RAM
on smaller parts, correct the H52x/H53x SPI count to SPI1-4 and drop the
STM32_STM32H5X3XX select, which names no symbol.

CONFIG_STM32F7_LCD_BACKLIGHT is not defined by any Kconfig, so the LTDC
backlight control is dead code.  CONFIG_STM32F7_PLLSAI and
CONFIG_STM32F7_PLLI2S are defined by the board.h files, and the common

Use the common CONFIG_STM32_* names everywhere.

Also drop the misspelled CONFIG_STM32F7_STM33F75XX from the DMA chip
check, which already tests CONFIG_STM32_STM32F75XX.

The CAN section of the STM32F7 documentation names the options
CONFIG_STM32F7F7_CANx, which has a duplicated family prefix and never
existed.  Use the common names there too.

eaaba5e0a1 arch/arm/rtl8721f: add PWM master driver support
Wire the shared Ameba PWM driver (arch/arm/src/common/ameba/ameba_pwm.c)
to RTL8721F (amebagreen2).  The chip spreads PWM across four four-channel
timers (TIM4..TIM7); this port drives TIM4 as the single time base with
four compare channels, matching the shared driver's model.  A new
ameba_pwm_chip.h supplies the RTL8721F specifics taken from the SDK
fwlib headers: TIM4 at the non-secure base 0x41000000, 40 MHz input
clock, IRQ 11 (TIMER4_IRQ), crossbar pad-mux codes 111..114
(PINMUX_FUNCTION_TIM4_PWM0..3) and the distinct function/clock enable
bits (APBPeriph_PWM0 / APBPeriph_PWM0_CLOCK).

The board registers one timer at /dev/pwm0 with channel 1 on PB18 and
channel 2 on PB19 for the pwm example; edit the table to match a board's
wiring.  The common driver is not touched.

6f2e17c113 arch/arm/rtl8721dx: add shared Ameba PWM driver
Add a shared NuttX PWM lower-half for the Realtek Ameba PWM timer in
arch/arm/src/common/ameba, driven through the SDK fwlib.  TIM8 provides a
single time base feeding eight compare channels (CCR0..CCR7) that share one
frequency while each carries its own duty, so a single /dev/pwm0 exposes the
multichannel output via CONFIG_PWM_NCHANNELS.  The fwlib PWM routines are
split ROM/RAM: the time-base calls resolve from on-chip ROM, while the
capture/compare calls live in fwlib ram_common/ameba_tim.c, which the build
pulls into AMEBA_FWLIB_SRCS when CONFIG_AMEBA_PWM is set.

Per-chip wiring (timer index, channel count, register base, input clock,
IRQ, clock masks and the crossbar pad-mux code table) lives in
arch/arm/src/rtl8721dx/ameba_pwm_chip.h so a port to another Ameba chip only
supplies a same-named header; the pad-mux codes are a per-channel table
(AMEBA_PWM_PINMUX_FIDS) rather than a computed base, so chips with a single
shared code or codes grouped per timer are expressed by the header alone.

The timer registers as /dev/pwm0 from pke8721daf bring-up through the stock
PWM character driver; a dedicated `pwm` defconfig drives examples/pwm for
validation.
