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.

# $FreeBSD$
loader: set options before including bsd.init.mk bsd.init.mk ends up including defs.mk so the per-arch options must be set before including defs.mk, or else the global defaults will be used and the per-arch ones will be ignored. Although better, note that the usage of MK_FDT before the inclusion of bsd.init.mk is incorrect but doesn't lead to build errors. This circular dependency must be broken in order for this to work correctly. Reviewed by: imp Sponsored by: Citrix Systems R&D

Install the 4th files in sys/boot/forth instead of each loader Also, move generation of loader.help into loader.mk. Set HELP_FILES= to disable this (so we only install one help file, for now). At the same time remove some duplicate -I lines. Fix several FILES= and CLEANFILES= into the += form since we're touching both of those in the .mk files. Make sure we only build one loader.help file per platform in a unified way (we were building many on some, with the last to install winning, though often they were the same text). Also, we're now installing loader.rc and menu.rc everywhere. arm and mips uboot installed these as menu.rc.sample, but there's no need since the loader.rc for those platforms doesn't do menu.rc processing by default. pcibios.4th is now installed everywhere, but will failsafe on non x86 platforms (it isn't loaded by default anywhere). These changes are too intertwined to do separately since aspects of each are required to have a bug-free commit. Sponsored by: Netflix

mips: ubldr: use truncated load address for mips32 BFD appears to silently truncate 0xffffffff80800000 when it processes the ldscript for 32-bit mips, but LLD chokes on it as the linker script tries to place elements above 32-bit range. It's unclear to me if silent truncation is kosher or not and whether this patch is really what we want to do, but it is one approach at least.

Move loader help file definitions to being 100% inside of loader.mk. HELP_FILES is a loader only thing, so move it to loader.mk. Only generate the help file if HELP_FILES is defined.

Move some more common stuff up to Makefile.inc. In particular, the no simd / no float stuff is centeralized here. Also centralise -ffreestanding since it is specified everywhere. This, along with a change to share/mk/bsd.cpu.mk to include -mno-avx2 in CFLAGS_NO_SIMD should fix building for newer machines (eg with CPUTYPE=haswell) where clang was generating avx2 instructions.
