Implement PIC loading in armv8-m qemu,
for example: load address-independent AP ELF in the bootloader,
and the text segment in AP ELF is XIP,
no need to apply for memory and modify it.
Two config:
bootloader abbreviation bl:
use romfs to load ap elf, use the boot command to parse and jump to ap
application abbreviation ap:
run os test
We need to compile ap first, then compile bl.
compile step:
./tools/configure.sh mps3-an547:ap
make -j20
mkdir -p pic
cp boot pic/.
genromfs -a 128 -f ../romfs.img -d pic
make distclean -j20
./tools/configure.sh mps3-an547:bl
make -j20
run qemu:
qemu-system-arm -M mps3-an547 -m 2G -nographic -kernel nuttx.bin \
-gdb tcp::1127 -device loader,file=../romfs.img,addr=0x60000000
nsh> boot /etc/boot
ap> ostest

The segment of the Xen PVH boot protocol was not specified during linking and was placed before .loader.text, causing the boot to fail

Summary:
1. The start location of FLASH reserves the extended bootloader
2. DTB data is reserved at the start location of RAM

Added a flash driver for the STM32G4 series. The primary change here is
the addition of stm32g4xxx_flash.c. This file uses the STM32L4 flash
driver as a template. The primary difference is the accounting for dual
banks with different page sizes.
Fixed error while building b-g474e-dpow1/buckboost. It was possible (technically) to have page be used uninitialzied. Changing the if statement to default to using a flash_page_size == 2048 fixes this issue.
Avoid compilation errors due to insufficient flash in CI
