0d203a6065 Create a custom /boot/defaults/loader.conf for ARM. This differs from the
standard file in the following ways:

 - modules_path includes /boot/dtb
 - It doesn't contain 533 lines, of which 500 are either commented out,
   empty, or something_which_doesnt_work_on_arm_anyway=NO

The standard defaults file takes 40+ seconds to process on an arm beaglebone
board.  This one takes just a couple seconds.

This gets installed instead of the original because of the .PATH magic in
the makefile.

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.

6d4766c1b8 Remove MK_ARM_EABI, the armeb issues have been fixed. The code to support
the oabi is still in the tree, but it is expected this will be removed
as developers work on surrounding code.

With this commit the ARM EABI is the only supported supported ABI by
FreeBSD on ARMa 32-bit processors.

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.

8926f21ce1 Enable at91 systems to boot from high capacity SD cards.
This also fixes a few minor violations of the SD protocol, such as running
the bus at high speed during the card identification sequence.

The sdcard_init() routine now probes for SDHC cards so that later read
requests can make needed adjustments between block and byte offsets based
on card type.

There is a new MCI_readblocks() function that takes block number and block
count parameters instead of byte-offset values.  Using this routine, boot
loader code can load a kernel from any location on an SDHC or standard SD.

The old MCI_read() interface remains unchanged so that existing customized
boot loader code will still keep working without changes.  Using this
routine, boot loaders can load a kernel from anywhere in the first 4GB of
an SDHC card (or of course any location on a standard SD card).

A new sdcard_use4wire() routine allows boot loaders to request 4-bit
transfers; it should be called after sdcard_init().  The sdcard_init()
routine no longer assumes the hardware is 4-wire capable and by default
sets things up for 1-bit transfers.  (4-wire mode is unreliable on
at91rm9200, works on later SoCs.)

7a22215c53 Fix undefined behavior: (1 << 31) is not defined as 1 is an int and this
shifts into the sign bit.  Instead use (1U << 31) which gets the
expected result.

This fix is not ideal as it assumes a 32 bit int, but does fix the issue
for most cases.

A similar change was made in OpenBSD.

ca49624410 Fix ixp425 boot2 with ARM EABI:
- libkern is missing __aeabi_llsl, implement this by calling __ashldi3.
 - Because of how the asm entry macros are defined the boot2 code
   requires the unwind symbols to exist, include them in boot2.
