telink compiler do not support float point, so set LIBC_RAND_ORDER
to be 0 to avoid function srand() use float point.

The default bpp is STM32_LTDC_L1_L8, when TM32_FB_CMAP=y,and The default bpp is STM32_LTDC_L1_RGB565 when TM32_FB_CMAP=n. The color-format bpp of stm32f429i is 16, so we should be disable TM32_FB_CMAP, otherwise fb demo will result in an error.

up_interrupt_context indicates that we self inside interrupt/handler mode,
replaced to private function is_nesting_interrupt to make less confused.

The case want to determine if a interrupt with higher priority and the
interrupt preemption occurred, but up_interrupt_context indicates that we
self inside interrupt/handler mode. As we previously did not handle the
ramvector interrupt correctly, after update breaked the case. We should
use a more clear private function is_nesting_interrupt.

during migration from legacy pinout some of the FMC pins were ommited because
their names were identical to the new pinout, which didn't cause a compilation error.
This fixes LCD examples.
Also update incomplete stm32f769i-disco FMC support to avoid this kind of bug in the future
Add heap current used to note.
Plot it in segger sysview data plot.

1. Kconfig - Removed USART1 config option from STM32_STM32G47XX. Not necessary to adding LPUART functionality. 2. stm32_lowput.c - Added extra check from STM32G4 board because that is the only with LPUART functionality. 2. stm32_serial.c - Removed unneeded function (stm32_serial_get_lpuart). Fixed up_putc return bug. Added configuration for DMAMAP_LPUART RX and TX for STM32G4XXX only. The G4 is the only in this family with LPUART and uses a DMAMUX unlike the others.
1. Removed 1WIRE LPUART refereences in Kconfig and stm32_uart.h. There is no support for LPUART currently in stm32_1wire.c. 2. Removed references to LPUART under DMA_V2 ifdefs. STM32G4 uses DMA_V1, and I saw that none of the chips DMA_V2 (F20, F4) have LPUARTs. AFAIK the only chip in the stm32 folder that has LPUART peripherals is the STM32G4.
Removed unnecessary brackets and empty lines
Added lpuartnsh (LPUART NuttShell) config to the nucleo-g474re board configurations. nsh uses USART3 by default. lpuartnsh uses nsh as a template, changes the serial console to LPUART1, and adds the DMA configs to enable DMA for the LPUART.
Added support for using the lpuart prescaler register. Without prescaling the apbclock, 9600 baud is not supported on the G474RE. By utilizing the prescaler, when necessary, we can support nearly any baud rate (300 baud to 30M Mbaud). lowputc defaults to a prescaler of 16 for the lpuart so standard baud rates (9600 to 115200) are supported early in the boot process. Later in stm32_serial.c the ideal prescaler and BRR values are determined.
Added ifdef statements for LPUART code sections not compatible with other chips.
Changed LPUART BRR calcuation to use 64-bit integers.
Feedback from nuttx pull request. Added brackets around single line if/else statements. Reordered lpuartnsh defconfig file.
Fix lpuart brr calculation after attempting to break the calculation into 2 lines.
Removed TAB
read content of undefinedinsn address, and compare it with what it is in elf to check if there is a ram bit flip

Since the size of the shadow area will change during the script merging of global variables, it will lead to unpredictable number of links. After fixing, only three links are required.
