MFC r285138:

Install loader.rc with ARM u-boot loader (ubldr).

loader.rc is the responsible to read and process loader.conf variables.

This fix the issue of loader.conf being silently ignored.

MFC r283033, r283062, r283066, r283069:

Do not set preload_addr_relocate for ARM.

Refactor net_getparams() to make it easier to get params from sources other
than bootp and rarp.

Add a routine to obtain netboot parameters from the U-Boot env vars

Enable the NETIF_OPEN_CLOSE_ONCE option for ubldr.

MFC r277962, r277988, r282661, r282727, r282731, r283013, r283035:

Add support for booting relocatable kernels on PowerPC.

Add code to support loading relocatable kernels at offsets that are
not zero.

Move ubldr text section to the start of the output file, so that when you
create a stripped .bin file from it the entry point is the first byte of
the file. (Will allow "load $addr $file ; go $addr" in u-boot.)

Create a relocatable instance of ubldr for ARM (ubldr.bin).

Re-link ubldr when any of its libraries change.

An ARM kernel can be loaded at any 2MB boundary, make ubldr aware of that.

MFC r276632: Create a custom /boot/defaults/loader.conf for ARM.

MFC r276145: Convert lingering NO_FORTH conditionals to test MK_FORTH.

MFC 273927:

Move the definitions of the fdt functions from a uboot header to a new fdt
header. There is nothing in the fdt spec that ties it to U-Boot.

While here sort and fix the signature of fdt_setup_fdtp.

MFC 273934:

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.

MFC r271285:

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).

MFC r257210, r258527: No hardfloat in ubldr, save/restore r9 for api calls.

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.

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

Provide verbose help for fdt commands on platforms that use it.

* 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.

Link against compiler-rt to pull in the required __aeabi_* functions

Ignore a warning in ubldr where clang doesn't understand the %D printf
specifier from libstand.

Handle LOADER_NO_DISK_SUPPORT knob in the arm and powerpc ubldr.

Allow the load address used by ARM ubldr to be set via Make argument.

In particular, this simplifies scripts that build system
images.

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.

Remove some redundant register loads.

Discussed on: arm@

We no longer need the OUTPUT_FORMAT line, so fix the build by removing it.

It turns out that the OUTPUT_FORMAT should do the right thing for both endians...

MF tbemd: differentiate between arm and armeb

Fix conditional FDT support in loader(8).

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.

Let ARM loader(8) build with the man page.

Initial storage functionality for U-Boot support library.

- Only non-sliced bsdlabel style partitioning is currently supported (but provisions
are made towards GPT support, which should follow soon)
- Enable storage support in loader on ARM

Obtained from: Semihalf

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.
