Fix boot from NOR due to incorrect reset delay.
AT91 RSTC registers are battery-backuped, so their values
are not reset across power cycles. One of those registers,
the AT91_RSTC_MR register, is being modified by U-Boot, in
the ethernet initialisation routine, to generate a 500ms
user reset.
Unfortunately, this value is not being restored afterwards,
causing subsequent resets to also last for 500ms.
This long reset sequence causes problems (at least) in the
boot sequence from NOR: by the time the CPU tries to load
a program from the NOR flash, the latter is still in reset
and not yet available.
Additionaly, this patch fixes a bug in the original code which
caused the reset delay to last for 2s instead of 500ms.

i.MX31: fixed CTRL-C detection
The Register URXD contains status information in bits [15..8].
With status bit 15 set, CTRL-C was reported as 0x8003 instead
of 0x03. Therefore CTRL-C was not detected.
To solve this, bits [15..8] were masked out now.

This moves the MMC and SD Card command definitions from
include/asm/arch/mmc.h into include/mmc.h. These definitions are
given by the MMC and SD Card standards, not by any particular

There's a lot more room for consolidation in the MMC drivers which
I'm hoping to get done eventually, but this patch is a start.

Resize device tree to allow space for board changes and the chosen node
Current code requires that a compiled device tree have space added to the end to
leave room for extra nodes added by board code (and the chosen node). This
requires that device tree creators anticipate how much space U-Boot will add to
the tree, which is absurd. Ideally, the code would resize and/or relocate the
tree when it needed more space, but this would require a systemic change to the
fdt code, which is non-trivial. Instead, we resize the tree inside
boot_relocate_fdt, reserving either the remainder of the bootmap (in the case
where the fdt is inside the bootmap), or adding CFG_FDT_PAD bytes to the size.

When compile-testing on powerpc, I get errors like this:
net/nfs.c:422: undefined reference to `__stack_chk_fail_local'
This seems to be because -fstack-protector is on by default, so
let's explicitly disable it on all architectures that support the
option.
The Ubuntu toolchain is affected by this problem, and according to
Mike Frysinger, Gentoo has been running with SSP enabled for years.
More and more distros are turning SSP on by default, so this problem
is likely to get worse in the future.
Also, powerpc just happens to be one of the arches I do
compile-testing on. There may be other arches affected by this too.

This patch simplifies flash_toggle() (AMD commandset), which is used to
detect if a FLASH device is still busy with erase/program operations. On
800MHz Canyonlands/Glacier boards (460EX/GT) the current implementation
did not detect the busy state reliably, resulting in non erased sectors
etc. This patch now simplifies this function by "just" comparing the
complete data-word instead of ANDing it with the command-word (0x40)
before the compatison. It is done the same way in the Linux implementation
chip_ready() in cfi_cmdset_0002.c.

ppc4xx: Canyonlands: Disable the RTC M41T62 square wave output
This patch disables the square wave output of the M41T62 RTC used on
Canyonlands & Glacier. Here the explanation:
The serial real-time clock part used in the design is an
STMicro M41T62. This part has a full-time 32KHz square wave
output that is connected to the TmrClk input to the
processor. The default state for this square wave output is
enabled so the output runs continuously when the board is
powered normally and also from the battery. The TmrClk input
to the processor goes to ground when the power is removed
from the board/processor, and therefore the running square
wave output is driving ground which drains the battery quickly.

Broke building on some systems, because the host's string.h was interfering
with u-boot's linux/string.h. It doesn't look like we need the u-boot one if

Change initdram() return type to phys_size_t
This patch changes the return type of initdram() from long int to phys_size_t.
This is required for a couple of reasons: long int limits the amount of dram
to 2GB, and u-boot in general is moving over to phys_size_t to represent the
size of physical memory. phys_size_t is defined as an unsigned long on almost
all current platforms.
This patch *only* changes the return type of the initdram function (in
include/common.h, as well as in each board's implementation of initdram). It
does not actually modify the code inside the function on any of the platforms;
platforms which wish to support more than 2GB of DRAM will need to modify
their initdram() function code.
