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

Use BOOTDIR consistently. We need to include bsd.init.mk early to make this happen. This will cause src.opts.mk to be included, so remove that. This needs to propigate through the sys/boot tree. 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.

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
