to the boot.netif.mtu env var, which will be picked up by pre-existing code
in nfs_mountroot() and used to configure the interface accordingly.
This should bring the same functionality when the bootp/dhcp work is done
by loader(8) as r297150 does for the in-kernel BOOTP case.
The following pheripherals are supported: UART, MMC, AHCI, EHCI, PCIe, I2C,
PMIC, GPIO, CPU temperature and clock.
Note: The PCIe driver is pure mash at this moment. It will be reworked
immediately when both D5237 and D2579 enter the current tree.
After ARM_INTRNG introduction, MPIC code needed several modifications:
- IRQ resource and its handler added
- several DEVMETHODs of INTRNG interface implemented
- defines enhanced to ensure code compiles as well for AXP as for A38X
- added dummy MSI_IRQ, ERR_IRQ defines for Armada38x
- MPIC driver was added to files.armada38x, ARM_INTRNG option enabled in
kernconf file and regs of MPIC corrected in dts file.
Instead of modifying Armada38X DTS, offsets to CPU registers defined in
driver were changed. That required restoring 'reg' property of mpic node
in ArmadaXP to state compliant with Linux DTS.
Additionally, required ARM_INTRNG definitions were added to mv_common.c.

Until now, ubldr has been trying to locate the U-Boot API using a hint
address (U-Boot's current stack pointer), aligning it to 1MiB and going
over a 3MiB (or 1MiB in case of MIPS) memory region searching for a
valid API signature.
This change introduces an alternative way of doing this, namely the
following:
- both U-Boot's bootelf and go commands actually pass argc and argv to
the entry point (e.g., ubldr's start function, but they should also
be passed over to main() transparently)
- so, instead of trying to go and look for a valid API signature, we
look at the parameters passed to main()
- if there's an option '-a' with argument, which is a valid hexadecimal
unsigned long number (x), we try to verify whether we have a valid
API signature at address x. If so - we use it. If not - we fallback
to the original way of locating the API signature.
The U-Boot change, which causes the API structure address to be
exported as an environment variable, was committed to mainline U-Boot
as commit 22aa61f707574dd569296f521fcfc46a05f51c48

the boot loader should not skip over these anymore while loading images.
Otherwise the kernel can still panic when it doesn't find the .eh_frame
section belonging to the .rela.eh_frame section.
Unfortunately this will require installing boot loaders from sys/boot
before attempting to boot with a new kernel.

(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
API (we're passing only pointers, no obvious reason to cast them to uint32_t),
cleaning up some compiler warnings and using the proper printf format
specifiers in order to be able to compile cleanly for both 32-bit and 64-bit
MIPS targets.

It is an improvement over the existing setreg(), setmsr(), setcr()
setgdt() and exec() callbacks in that the new additions give full
