Please add build instructions to roms/Makefile. I dunno how this one is related to roms/vbootrom which is already used for npcmxxx_bootrom.bin files - maybe all the 3 bootroms should be kept in sync. Right now, with no instructions in roms/Makefile, it's problematic. Thanks, /mjt

Each has its own directory. They can't be independent, from qemu PoV anyway, since both comes from the same submodule (roms/vbootrom), - we can't update individual subdirs in a submodule, we can update either whole submodule or not at all. Thanks, /mjt

Updating the vbootrom submodule to the latest shouldn't be an issue for the Nuvoton's images. We should do that when the fix for the aspeed Makefile is pulled in. Thanks, C.

It seems this patch fix this issue, https://patchwork.kernel.org/project/qemu-devel/patch/607a943a587248fbe0ff0897de80aee98a093caa.1753654515.git.mjt@tls.msk.ru/
Do I need to update vbootrom/ast27x0/Makefile?
I set "?=" to make user able to set variables in the command line.
1.
export CC=aarch64-linux-gnu-gcc
make
2. make CC=aarch64-linux-gnu-gcc
3. Update Make file and user only need to issue "make"

Update Make file and user only need to issue "make" See how it's done in other subdirs of vbootrom. You only need to remove ? from CC variable assignment. Distinction between 1 and 2 is `make -e` command-line switch. Thanks /mjt
