The purpose of this patch is to prepare for adding the OMAP4 architecture, which is Cortex A9
Cortex A8 and A9 both belong to the armv7 architecture, hence the name change.
The two architectures are similar enough that substantial code can be shared.

The hush shell dynamically allocates (and re-allocates) memory for the
argument strings in the "char *argv[]" argument vector passed to
commands. Any code that modifies these pointers will cause serious
corruption of the malloc data structures and crash U-Boot, so make
sure the compiler can check that no such modifications are being done
by changing the code into "char * const argv[]".
This modification is the result of debugging a strange crash caused
after adding a new command, which used the following argument
processing code which has been working perfectly fine in all Unix
systems since version 6 - but not so in U-Boot:
int main (int argc, char **argv)
{
while (--argc > 0 && **++argv == '-') {
/* ====> */ while (*++*argv) {
switch (**argv) {
case 'd':
debug++;
break;
...
default:
usage ();
}
}
}
...
}
The line marked "====>" will corrupt the malloc data structures and
usually cause U-Boot to crash when the next command gets executed by
the shell. With the modification, the compiler will prevent this with
an
error: increment of read-only location '*argv'
N.B.: The code above can be trivially rewritten like this:
while (--argc > 0 && **++argv == '-') {
char *arg = *argv;
while (*++arg) {
switch (*arg) {

Add USB OHCI support for at91sam9g45ekes/at91sam9m10g45ek boards.
Note that according to errata from Atmel, OHCI is not operational
on the first revision of at91sam9g45 chip. So this patch enables
OHCI support for later revisions.

The ARM ABI requires that the stack be aligned to 8 bytes as it is noted
in Procedure Call Standard for the ARM Architecture:
http://infocenter.arm.com/help/topic/com.arm.doc.ihi0042d/index.html
Unaligned SP also causes the problem with variable-length arrays
allocation when VLA address becomes less than stack pointer during
aligning of this address, so the next 'push' in the stack overwrites
first 4 bytes of VLA.

Currently EMAC_MDIO_PHY_NUM is defined as 1 in emac_defs.h.
Because of this, EMAC does not work on EVMs which do not have phy
connected at 1. Moving the macro to board config file makes this
configurable depending on where the phy is connected on the MDIO bus.
This patch fixes the board reset issue observed during network access
on DM365EVM. EMAC driver was assuming EMAC_MDIO_PHY_NUM as 1
but it is 0 on DM365EVM.
This patch is verified on da830/omap-l137, dm365 and dm644x evms.

The push / pop instructions used in this file are available only with
more recent tool chains:
cache.S: Assembler messages:
cache.S:133: Error: bad instruction `push {r0,r1,r2,lr}'
cache.S:160: Error: bad instruction `pop {r1,r2,r3,pc}'
cache.S:164: Error: bad instruction `push {r0,r1,r2,lr}'
cache.S:191: Error: bad instruction `pop {r1,r2,r3,pc}'
Change push/pop into stmfd/ldmfd instructions to support older
versions of binutils as well.
I verified that the modified source code generates exactly the same
binary code.

Part of this patch is by: Mikhail Kshevetskiy.
Stack must be aligned to 8 bytes on PXA (possibly all armv5te) for LDRD/STRD
instructions. In case LDRD/STRD is issued on an unaligned address, the behaviour
is undefined.
The issue was observed when working with the NAND code, which was rendered
disfunctional. Also, the vsprintf() function had serious problems with printing
64bit wide long longs. After aligning the stack, this wrong behaviour is no
longer present.
Tested on:
Marvell Littleton PXA310 board
Toradex Colibri PXA320 board
Aeronix Zipit Z2 PXA270 handheld
Voipac PXA270 board

The current ARM1176 CPU specific code is too specific to the SMDK6400
architecture. The following changes were necessary prerequisites for the
addition of other SoCs based on ARM1176.
Existing board's (SMDK6400) configuration has been modified to keep behavior
unchanged despite these changes.
1. Peripheral port remap configurability
The earlier code had hardcoded remap values specific to s3c64xx in start.S.
This change makes the peripheral port remap addresses and sizes configurable.
2. U-Boot code relocation support
Most architectures allow u-boot code to run initially at a different
address (possibly in NOR) and then get relocated to its final resting place
in RAM. Added support for this capability in ARM1176 architecture.
3. Disable TCM if necessary
If a ROM based bootloader happened to have initialized TCM, we disable it here
to keep things sane.
4. Remove unnecessary SoC specific includes
ARM1176 code does not really need this SoC specific include. The presence
of this include prevents builds on other ARM1176 archs.
5. Modified virt-to-phys conversion during MMU disable
The original MMU disable code masks out too many bits from the load address
when it tries to figure out the physical address of the jump target label.
Consequently, it ends up branching to the wrong address after disabling the
MMU.

The ARM1136 cache_flush() function uses the "mcr p15, 0, rn, c7, c7, 0"
instruction which means "Invalidate Both Caches" when in fact the intent
is to clean and invalidate all caches. So add an "mcr p15, 0, %0, c7,
c10, 0" instruction to "Clean Entire Data Cache" prior to the "Invalidate
Both Caches" instruction to insure that memory is consistent with any
dirty cache lines.
Also fix a couple of "flush v*" comments in ARM1136 cpu_init_crit() so
that they correctly describe the actual ARM1136 CP15 C7 Cache Operations
used.
