[PATCH 0/3] bootconfig: Make size and checksum fields le32

[Masami Hiramatsu]

Hello,

This is a series of patches to make the size and the checksum fields
in the footer le32 instead of u32.

In the thread for alignment series[1], Steve pointed that the current
footer format didn't specify the endianness thus it is hard to apply
the bootconfig for cross-build initrd if the target endianness is
different from the host machine.

I've proposed that the hexadecimal ASCII string in the previous series
[2] but Linus pointed that making it le32 was enough.

So this just make those fields le32.

Thank you,

Hrm, this kind of things usually good for the next merge window because
it is only for the different endianess cross-build case. But the next
release will be LTS (6 years life cycle), so it is possible someone
hits this issue before EOL and (I guess) finally they need this series.

So if possible, could you push this in -rc release? I think this doesn't
change so much.

Thank you,

I have this all tested. Is this something that should go into the current
-rc release, or wait for the next merge window?
