Disable some compiler warnings for GCC (non-standard compiler) fixing
build failures introduced by r293724, which enabled WARNS in the EFI boot
code, when compiling with none standard compiler (GCC).

access and reopening it before the next (causing it to re-obtain network
params each time). This vastly speeds up netbooting.
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.

- 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.

needs to be a new library for linking to work correctly.

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.
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.)

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.

- 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.

for the at91rm9200, but still need to trim for the target.
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.

# This doesn't implement the full Linux boot ABI for arm yet.
# since there's no ATAGs list passed in for r2, and r0 has
# boot options rather than 0 as specified in the standard.
# Commited code to the tree won't touch any of this anyway, but
# future code may be able to use this.
If I interpret the C standard correctly, the storage specifier should be
placed before the inline keyword. While at it, replace __inline by
inline in the files affected.
