[RFC PATCH 0/3] bootconfig: Use hexadecimal ASCII string for size and checksum

Hello,

Here is a seires of patches to change the bootconfig footer format
to use 8-bytes hexadecimal ASCII string for size and checksum instead
of u32.

In the previous thread for alignment series[1], Steve pointed that
the current footer format makes it hard to apply the bootconfig for
cross-build initrd if the target endianness is different from the
host machine.

So, this changes the size and checksum format to 8-bytes hexadecimal
ASCII string as same as cpio. Since that is a string, we don't need
to care of the difference of the endianness anymore.

Thank you,
