The Makefile rule to create vers.c for loader version info was
previously duplicated in each of the various loader Makefiles.
Instead, share a common rule in Makefile.inc.

The NETIF_OPEN_CLOSE_ONCE flag was added in r201932 to prevent that behaviour
on some architectures (sparc64 and powerpc64) the default was left to always
open and close the device for each open and close of a file by the loader
because it was necessary for u-boot on arm.
Since it has been added, the flag was turned on for every arches including the
u-boot loader for arm.
This also fixes netbooting on RPi3 (tested by gonzo@)

alignment aborts in ubldr.bin for RPi that started happening with clang 3.8
(earlier clang apparently didn't generate strd instructions that trigger
the alignment fault). The abort happened in ubldr.bin and not ubldr (elf
version) because the elf headers are 0xf4 bytes long, and stripping them
off left everything 4-byte aligned.
While here, also stop aligning the data segment to a page boundary, align
it to 8 bytes instead (aligning to a page just needlessly makes the file
bigger); pointed out by andrew@.
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).

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,

The standard defaults file takes 40+ seconds to process on an arm beaglebone

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

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.)

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.
