The initrd seems to works well, but it generates a strange failure
during the boot:
[...]
Mount-cache hash table entries: 512
Checking for 'wait' instruction... available.
checking if image is initramfs...it isn't (bad gzip magic numbers);
looks like an initrd
Bad page state in process 'swapper'
page:81010000 flags:0x00080000 mapping:00000000 mapcount:0 count:0
Trying to fix it up, but a reboot is needed

This message is not present when initrd is not used, and it also does
not appear with the previous way of passing the size and location of the
initrd.
I don't have time to look more now, I will give you some more details
when/if I found some time to work on that.
This failure is due to the fact that initrd_reserve_bootmem is not set
anymore to 1 in arch/mips/kernel/setup.c. It is set to 1 when the initrd
location and size are read from the command line arguments, but not when
read from the place where QEMU put it.
Setting this value to 1 fixes the problem, but it is rather a big hack
than a fix.
About the patch itself, another comment: you should add a #ifdef
CONFIG_BLK_DEV_INITRD #endif for the block concerning the initrd in
arch/mips/qemu/q-firmware.c
Bye,
Aurelien
