examples/standalone: Remove relocation compile flags for PowerPC

Previously, standalone applications were compiled with gcc flags that
produced relocatable executables on the PowerPC architecture (eg with
the -mrelocatable and -fPIC flags). There's no reason for these
applications to be fully relocatable at this time since no relocation
fixups are performed on standalone applications.

Additionally, removing the gcc relocation flags results in the entry
point of applications residing at the base of the image. When
a standalone application was relocatable, the entry point was generally
located at an offset into the image which was confusing and prone to
errors.

This change moves the entry point of PowerPC standalone applications
from 0x40004 (usually) to 0x40000.

hwconfig: Fix stop characters parsing for subkeys

For the following hwconfig string:

key1:subkey1=value1,subkey2=value2;key2:value3

The subkey2 cannot be extracted correctly. The parsing code looks
for comma as a stopch, but there may be two kind of stop characters:
a comma and a semicolon.

Currently the code would return "value2;key2:value3", while just
"value2" is the correct answer.

This patch fixes the issue by making the code aware of multiple
stop characters.

For old U-Boots, the issue can be workarounded by placing a comma
before a semicolon, i.e.:

hwconfig=key1:subkey1=value1,subkey2=value2,;key2:value3

MPC5200: workaround data corruption for unaligned local bus accesses

The MPC5200 has a nasty problem that will cause silent data corruption

be easily shown:

This commit implements a workaround at least for the most blatant
problem: using memcpy() from NOR flash. We rename the assembler
routine into __memcpy() and provide a wrapper, which will use a
byte-wise copy loop for unaligned source or target addresses when
reading from NOR flash, and branch to the optimized __memcpy()
in all other cases, thus minimizing the performance impact.

Tested on lite5200b and TQM5200S.

Davinci: SPI performance enhancements

The following restructuring and optimisations increase the SPI
read performance from 1.3MiB/s (on da850) to 2.87MiB/s (on da830):

Remove continual revaluation of driver state from the core of the
copy loop. State can not change during the copy loop, so it is
possible to move these evaluations to before the copy loop.

Cost is more code space as loop variants are required for each set
of possible configurations. The loops are simpler however, so the
extra is only 128bytes on da830 with CONFIG_SPI_HALF_DUPLEX
defined.

Unrolling the first copy loop iteration allows the TX buffer to be
pre-loaded reducing SPI clock starvation.

Unrolling the last copy loop iteration removes testing for the
final loop iteration every time round the loop.

Using the RX buffer empty flag as a transfer throttle allows the
assumption that it is always safe to write to the TX buffer, so
polling of TX buffer full flag can be removed.

I have updated this patch based on the comments [1] by Wolfgang Denk and
removed unused variables.
[1][http://lists.denx.de/pipermail/u-boot/2010-May/071728.html]

Reduce the number of reads per byte transferred on the BUF register from 2 to 1 and
take advantage of the TX buffer in the SPI module. On LogicPD OMAP-L138 EVM,
SPI read throughput goes up from ~0.8Mbyte/s to ~1.3Mbyte/s. Tested with a 2Mbyte image file.
Remove unused variables in the spi_xfer() function.

omap3: Consolidate SDRC related operations

Consolidated SDRC related functions into one file - sdrc.c

And also replaced sdrc_init with generic memory init
function (mem_init), this generalization of omap memory setup
is necessary to support the new emif4 interface introduced in AM3517.

omap3: Calculate CS1 size only when SDRC is

initialized for CS1

From: Vaibhav Hiremath <hvaibhav@ti.com>

The patch makes sure that size for SDRC CS1 gets calculated
only when the CS1 SDRC is initialized.

OMAP3EVM: Added NAND support

The EVMS have been shipping with NAND (instead of OneNAND) as default.
So, this patch sets NAND as default.

To choose OneNAND, define CMD_ONENAND instead of CMD_NAND in the
config file omap3_evm.h.

ARM1176: Coexist with other ARM1176 platforms

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.
