Hi U-Boot,
I've been given a MIPS reference board with a fairly old vendor U-Boot on it. It does seem to support the Mutli-File Image format but I'm running into an issue where the kernel expects the initrd on a page boundary.
I'm using a command like the following to produce and image cat board.dtb >> vmlinux.bin gzip vmlinux.bin >vmlinux.gz mkimage -C gzip -A mips -O linux -T multi -a 0x80100000 -e 0x80100000 -d vmlinux.gz:initrd.sqsh myboard.img
I can mess about with padding vmlinux.gz after the gzip step but the process is a bit fragile and involves me guessing at some magic numbers that I think might be sizes of certain headers.
Is there any way to convince mkimage to make sure the initrd is on an appropriately aligned boundary so I don't have to guess.
Thanks, Chris
