Re: fitImage align 8-byte for ARM64

Hi!

I have had trouble booting a fitImage packed kernel for dragonboard410c, which is an ARM64 platform. After days and days of debugging, I found that the fdt is 4-byte aligned. But within the linux kernel, Documentation/arm64/booting.txt says, fdt must be 8 byte aligned.

If I change the alignment by means of fdt_high, the Kernel boots, otherwise, it hangs.

Is there an option to align the fitImage to 8-byte boundaries, and if not, is it feasible to submit a patch or will this never have a chance to get merged?!

That's interesting. It sounds like you need to look at boot_relocate_fdt() perhaps? Thanks!
