Re: [ptxdist] [PATCH] u-boot: Add support for u-boot.dtb and u-boot-nodtb.bin

[Alejandro Vazquez <avazquez.dev@gmail.com>]

You are right. I have the same problem, I will apply the solution you propose

On the other hand, it is possible to update only a part of the binary
(fip) with the fiptool update command. So, I think it is interesting
install the files (u-boot.dtb and u-boot-nodtb.bin) on
platform/images.

For example.
fiptool update --hw-config u-boot.dtb fip.bin
