bc814587a9 Deduplicate loader vers.c Makefile rules
The Makefile rule to create vers.c for loader version info was
previously duplicated in each of the various loader Makefiles.
Instead, share a common rule in Makefile.inc.

5bca221511 Add full softfloat and hardfloat support for MIPS.
This adds new target architectures for hardfloat:
mipselhf mipshf mips64elhf mips64hf.

Tested in QEMU only.

1b46e63d3c Stop closing the network device when netbooting for loaders using the common
dev_net.c code.

The NETIF_OPEN_CLOSE_ONCE flag was added in r201932 to prevent that behaviour
on some architectures (sparc64 and powerpc64) the default was left to always
open and close the device for each open and close of a file by the loader
because it was necessary for u-boot on arm.

Since it has been added, the flag was turned on for every arches including the
u-boot loader for arm.

This also fixes netbooting on RPi3 (tested by gonzo@)

For the loader.efi it greatly speeds up netbooting

8aa5c6cfeb remove CONSTRUCTORS from MIPS uboot linker script
The linker script CONSTRUCTORS keyword is only meaningful "when linking
object file formats which do not support arbitrary sections, such as
ECOFF and XCOFF"[1] and is ignored for other object file formats.

LLVM's lld does not yet accept (and ignore) CONSTRUCTORS, so just remove
CONSTRUCTORS from the linker script as it has no effect.

a1b701d82b 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.
