8c81befd0b Start to allow platforms other than U-Boot to use the FDT code in loader by 
moving U-Boot specific code from libfdt.a to a new libuboot_fdt.a. This
needs to be a new library for linking to work correctly.

6966304042 Add a 'ubenv import' command to import environment variables from the 
u-boot env into the loader(8) env (which also gets them into the kernel
env).  You can import selected variables or the whole environment.  Each
u-boot var=value becomes uboot.var=value in the loader env.  You can also
use 'ubenv show' to display uboot vars without importing them.

c6063d0da8 Use src.opts.mk in preference to bsd.own.mk except where we need stuff 
from the latter.

299f9dc1a6 Recent versions of U-Boot require us to also backup and restore r9 for API 
calls to work.

81f305d283 Always build ubldr as a soft-float binary as there is no support for VFP 
this early on in the boot process.

183abe44fa Install Forth infrastructure along with ubldr. 
Note:  loader.rc is installed as loader.rc.sample
so that by default, none of this is actually used.

6fb87f7371 When running on armv6, set alignment checking to modulo-4 mode rather 
than modulo-8, because clang emits ldrd and strd instructions for
addresses that are only 4-byte aligned

f892543501 * Add the integer div & mod functions and ARM EABI support functions to 
libstand.
* Stop linking the ARM U-Boot loader against libgcc now libstand has the
  required symbols.

81174e7872 Allow the load address used by ARM ubldr to be set via Make argument. 
In particular, this simplifies scripts that build system
images.

7f725bcd5c Import work done under project/nand (@235533) into head. 
The NAND Flash environment consists of several distinct components:
  - NAND framework (drivers harness for NAND controllers and NAND chips)
  - NAND simulator (NANDsim)
  - NAND file system (NAND FS)
  - Companion tools and utilities
  - Documentation (manual pages)

This work is still experimental. Please use with caution.

04cb90189b Initial loader(8) support for Flattened Device Tree. 
o This is disabled by default for now, and can be enabled using WITH_FDT at
  build time.

o Tested with ARM and PowerPC.

0ed948780c 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.
