Initial support of loader(8) for ARM machines running U-Boot. This uses the common U-Boot support lib (sys/boot/uboot, already used on FreeBSD/powerpc), and assumes the underlying firmware has the modern API for stand-alone apps enabled in the config (CONFIG_API). Only netbooting is supported at the moment. Obtained from: Marvell, Semihalf

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

Create a relocatable instance of ubldr for ARM. The original ubldr, static-linked to run at a fixed position, is still installed to maintain compatibility with existing configurations. The makefile now also creates and installs ubldr.bin, a stripped binary (no elf headers) with an entry point offset of 0 that can be loaded by u-boot at any address and launched with "go ${loadaddr}". To use ubldr.bin, U-Boot must still be built with the CONFIG_API option, but no longer needs the CONFIG_ELF option.

self_reloc.c: Pass -Wno-error=maybe-uninitialized to gcc versions greater than 4.2.1 self_reloc.c doesn't initialize `rel` in all cases in the C code, however, the value might be initialized properly on the stack in the assembly code. For right now (because this doesn't seem to be breaking anything and my initializing the stack value could break something since it's called from assembly code) disable the warning for self_reloc.c. More investigation should be done to determine the appropriate response to this warning (either intialize the value or find a smarter way to deal with the warning). A long MFC timeout is being set for this change to allow a better solution for the issue to be developed in that time period.

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. Adjust Makefiles to new convention. Fix a few cases where ${.CURDIR}/ was missing resulting in missing bits from the help files. Sponsored by: Netflix

Link EFI/uboot loaders with -znotext By default LLD links with relocations disallowed against readonly sections (e.g., .text), but the 32-bit ARM EFI & uboot boot bits require such relocations. -znotext is either ignored as an unknown -z option (in-tree lld 2.17.50) or is already the default (GNU ld or GNU gold from ports) so we can just add it unconditionally to allow building with LLD. This is similar to the change in r320179 for the kernel link. Sponsored by: The FreeBSD Foundation
