These are the configurations whose application reads the USB HID keyboard
as a byte stream. Now that the driver reports through the keyboard upper
half, they need INPUT_KEYBOARD_BYTESTREAM to keep behaving as before.
INPUT drops out of the normalised defconfigs because USBHOST_HIDKBD now
selects it.

Add EHCI and OHCI USB host drivers for the Ingenic JZ4780 SoC, derived
from the existing sama5 implementation.
Additionally, introduce the display controller driver using code ported
from FreeBSD under its original license terms. Note that this driver
lacks EDID support and is currently hardcoded to 1360x768.
Update the linker script memory layout to utilize the full 256 MiB RAM,
excluding the 8 MiB reserved at the top of memory for the framebuffer.

The common mips_cache.S only handles generic L1 cache operations and
does not support L2 (secondary) cache operations required for the
JZ4780 target.
This commit introduces mti_cache.S to support both L1 and L2 cache
operations.
The mti_cache.S implementation is BSD licensed from Imagination
Technologies.

Introduce networking capabilities to the Creator CI20 board by leveraging
the pre-existing dm9000 ethernet driver.
To achieve this, the following changes were made:
- Integrated the jz4780 GPIO module to properly configure and enable the
interrupt pin required by the ethernet controller.
- Added `dm90x0.h` to export the dm9000 initialization function, allowing
the board-specific setup code to initialize the network interface.

This commit introduces a rudimentary architecture and board port for the
MIPS Creator CI20, featuring the dual core Ingenic JZ4780 SoC (MIPS32).
Included in this initial implementation:
- Basic architectural initialization and startup code for the JZ4780 Core 0.
- Minimal configuration required to execute from RAM.
- Early UART/serial console support for basic debugging and NSH output.
- Minimal board-specific configuration for the CI20 target.
- Console output is routed via UART0 on the expansion header.
This establishes basic support for running NuttX on the MIPS CI20.
Further peripherals, optimization, and extended documentation are left for
future iterations or community contributions.
Build and Runtime Deployment Info:
----------------------------------
The baseline can be configured, compiled using the MIPS MTI toolchain,
and loaded via U-Boot using the following commands (replace
<tftp_dir> with your local TFTP root directory).
./tools/configure.sh -l ci20/nsh
make CROSSDEV=mips-mti-elf-
mkimage -A mips -O linux -T kernel -C none -a 0x80000180 -e 0x800004ac \
-n "nx" -d nuttx.bin <tftp_dir>/nuttx.umg
Note: U-Boot must be properly configured for networking (e.g., valid ipaddr,
serverip, and ethaddr environment variables) to fetch the image over TFTP.
Run this from U-Boot prompt:
tftp nuttx.umg && bootm $fileaddr

Permissions (Part 2)
Description:
In kernel builds, any unprivileged process running on the NuttX
device can open /dev/efuse and attempt to read/write fuse content.
Reading the fuses may provide valuable information to an attacker
controlling the user process. The write operation, in extreme cases
where the fuse blocks are not locked, may brick the device.
DISCLAIMER: I tried to be strict with the settings, better to relax them
later if it's needed.

BREAKING: In an effort to simplify NuttX initialization, NSH_ARCHINIT is
removed. board_app_initialize is also removed. BOARD_LATE_INITIALIZE now
performs all board initialization logic, and is by default enabled. All
references to these symbols are removed. BOARDIOC_INIT remains, but will
result in -ENOTTY when called. It is to be removed in a later commit.
Quick fix: Boards relying on NSH_ARCHINIT should now enable
CONFIG_BOARD_LATE_INITIALIZE instead. If the application needs
fine-grained control over board initialization from userspace, the logic
performed by BOARDIOC_INIT may be copied to the board_finalinitialize
function and used instead via BOARDIOC_FINALINIT. All
board_app_initialize logic provided by NuttX is now moved to
board_late_initialize, and the same should be done for out-of-tree
boards.

debug.h is a NuttX-specific, non-POSIX header. Placing it in the
top-level include/ directory creates naming conflicts with external
projects that define their own debug.h.
This commit moves the canonical header to include/nuttx/debug.h,
following the NuttX convention for non-POSIX/non-standard headers,
and updates all in-tree references.
A backward-compatibility shim is left at include/debug.h that
emits a deprecation #warning and re-includes <nuttx/debug.h>,
allowing out-of-tree code to continue building while migrating.

Correct duplicate "is is" word found in 181 files throughout the
codebase.
In most cases "is is" was changed to "is", but in contexts like
"MCU is is sleep mode" it was corrected to "MCU in sleep mode".
Also fixes a "the the" typo in net/inet/inet_sockif.c.
This is a pure style/documentation fix that improves code readability.

Most references to the readmes have been removed.
The removed references didn't make much sense and were inconsistent with other
sections of the code. Some sections linked to the readme, others didn't.
More importantly, most boards don't have any readme references.
Let's not treat developers as fools who need to be reminded at every step
to check the readme (which doesn't exit anymore anyway).

This is a supplement to the patch:1936126210a56b6d1b033d6d940669413dd6e1b0
Due to the automatic wrapping of MTD devices during the
open() process, the legacy registration methods
ftl_initialize() and bchdev_register() are no longer
required for MTD device registration for user code.
So we have adjusted the registration method for MTD devices
in nuttx/boards, replacing the previous approach using
ftl_initialize() with register_mtddriver().
Use configuration CDCACM_DISABLE_TXBUF or CDCACM_DISABLE_RXBUF to choose
whether to use usb req buffer as the serial buffer. Since the default
value is n (not using req buf), the original configuration of buf is valid.
This reverts commit 21c8ed80bd.
The Kconfig of system/usbmsc has updated to support setting paths that bind to LUN at runtime.
