[ImageBuilder] uboot-script-gen: fix arm64 xen u-boot image generation

Posted by Grygorii Strashko 10 months ago

From: Grygorii Strashko <grygorii_strashko@epam.com>

The current code in generate_uboot_images() does not detect arm64 properly
and always generates ARM u-boot image. This causes Xen boot issues.

Fix it by searching for "ARM64" for AArch64 binary detection.

- mkimage -l xen.ub
Before:
Image Type:   ARM Linux Kernel Image (uncompressed)

After:
Image Type:   AArch64 Linux Kernel Image (uncompressed)

My file -L gives:

for arm32: ARM OpenFirmware [...]
for arm64: Aarch64

So the ARM64 grep wouldn't work as intended. Is the version of `file'
that you are using really printing ARM64? If so, we can do:

  file -L $XEN | grep -E 'ARM64|Aarch64'

Hm, yes.

	file -L xen
	xen: Linux kernel ARM64 boot executable Image, little-endian, 4K pages

	file -v
	file-5.41

u-boot boot command:
	 bootm 0x4EA00000 - 0x4EE00000


  If so, we can do:

sure. I'll update.

Missing escape? I think it's needed even with single quotes.

  file -L $XEN | grep -E 'ARM64\|Aarch64'

No. It's extended regular expressions ("-E") no need for escape.
Also it works with both '' and "".

Ah, fair enough. My brain escaped the -E :)
