This review aims at introducing ubldr (loader with U-Boot interface) for MIPS (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.
