(32 and 64-bit, LE and BE).
The changes were tested with QEMU's 'mips' target.
Most of the implementation was lifted from the ARM version, the appropriate
MIPS-specific things were implemented.
With these changes I am able to go all the way through the u-boot->ubldr->kernel
boot chain in QEMU on all combinations of bit-ness and endian-ness.
For the tests I've used FAT32 disk images (as FAT32 is supported by U-boot),
which include /boot/kernel/kernel and /boot/kernel/ubldr.bin
In U-boot I do:
fatload ide 0 <LOAD_ADDR> /boot/kernel/ubldr.bin; go <LOAD_ADDR>
where LOAD_ADDR is 80800000 for 32-bit and ffffffff80800000 for 64-bit
Then it's the usual ubldr that takes over and loads and starts a kernel.

The changes are mostly dealing with removing unnecessary casts from the U-Boot

When processing loader.conf if console contained an entry for an unsupported
console then cons_set would return an error refusing to set any console.
This has two side effects:
1. Forth would throw a syntax error and stop processing loader.conf at that
point.
2. The value of console is ignored.
#1 Means other important loader.conf entries may not be processed, which is
clearly undesirable.
#2 Means the users preference for console aren't applied even if they did
contain valid options. Now we have support for multi boot paths from a
single image e.g. bios and efi mode the console preference needs to deal
with the need to set preference for more than one source.

* Returning CMD_OK where possible from cons_set.
* Allowing set with at least one valid console to proceed.

This builds on the modular EFI loader support added r294060 adding a
module to provide ZFS boot support on EFI systems.
It should be noted that EFI uses a fixed size memory block for all
allocations performed by the loader so it may be necessary to tune this
size.
For example when building an image which uses mfs_root e.g. mfsbsd, adding
the following to /etc/make.conf would be needed to prevent EFI from running
out of memory when loading the mfs_root image.
