Reset any i2c devices that may have been interrupted during a system reset.
Normally this would be accomplished by clocking the line until SCL and SDA
are released and then sending a start condtiion (From an Atmel datasheet).
There is no direct access to the i2c pins so instead create start commands
through the i2c interface. Send a start command then delay for the SDA Hold
time, repeat this by disabling/enabling the bus a total of 9 times.

Support USB on PSC3 on the mpc5200. Before this patch, enabling USB support
would reconfigure PSC4 and PSC5 to USB. The mpc5200 does not support USB
enabled on both the standard USB port and PSC3. This patch masks the
appropriate bits when enabling USB.

__attribute__ follows gcc's documented syntax and is generally more
common than __attribute. This change is only asthetic and should not

The previous code waited 1000us before checking i2c
status. Measurement shows i2c is usually ready in
under 50us. Change the polling interval to 15us,
loop 6,667 times to keep the polling timeout constant
at 100ms.

On boards which have the environment in eeprom, i2c_init() is called
before the console and RAM are initialized.
Suppress printfs until the console is initialized.

A recent gcc added a new unaligned rodata section called '.rodata.str1.1',
which needs to be added the the linker script. Instead of just adding this
one section, we use a wildcard ".rodata*" to get all rodata linker section
gcc has now and might add in the future.
However, '*(.rodata*)' by itself will result in sub-optimal section
ordering. The sections will be sorted by object file, which causes extra
padding between the unaligned rodata.str.1.1 of one object file and the
aligned rodata of the next object file. This is easy to fix by using the
SORT_BY_ALIGNMENT command.
This patch has not be tested one most of the boards modified. Some boards
have a linker script that looks something like this:
*(.text)
. = ALIGN(16);
*(.rodata)
*(.rodata.str1.4)
*(.eh_frame)
I change this to:
*(.text)
. = ALIGN(16);
*(.eh_frame)
*(SORT_BY_ALIGNMENT(SORT_BY_NAME(.rodata*)))
This means the start of rodata will no longer be 16 bytes aligned.
However, the boundary between text and rodata/eh_frame is still aligned to
16 bytes, which is what I think the real purpose of the ALIGN call is.

The environment is the canonical storage location of the mac address, so
we're killing off the global data location and moving everything to
querying the env directly.

Total5200 and digsy MTC use I2C port 2 pins as a ATA chip select.
To avoid adding board-specific ifdefs to cpu/mpc5xxx/ide.c new
define CONFIG_SYS_ATA_CS_ON_I2C2 was introduced. It is used by
Total5200 and will be used by digsy MTC and other boards with
ATA CS on I2C pins.

All implementations of the functions i2c_reg_read() and
i2c_reg_write() are identical. We can save space and simplify the
code by converting these functions into inlines and putting them in

Most of the bss initialization loop increments 4 bytes
at a time. And the loop end is checked for an 'equal'
condition. Make the bss end address aligned by 4, so
that the loop will end as expected.

At a lot of places in the code the PIPE_INTERRUPT flags and friends
are used wrong. The wrong bits are compared to this flag resulting
in wrong conditions. Also there are macros that should be used for
PIPE_* flags.
This patch tries to fix them all, however, I was not able to test the
changes, because I do not have any of these boards.
Review required!

This commit gets rid of a huge amount of silly white-space issues.
Especially, all sequences of SPACEs followed by TAB characters get
removed (unless they appear in print statements).
Also remove all embedded "vim:" and "vi:" statements which hide
indentation problems.

R29 was an unlucky choice as with recent toolchains (gcc-4.2.x) gcc
will refuse to use load/store multiple insns; instead, it issues a
list of simple load/store instructions upon function entry and exit,
resulting in bigger code size, which in turn makes the build for a
few boards fail.
Use r2 instead.

With recent toolchain versions, some boards would not build because
or errors like this one (here for ocotea board when building with
ELDK 4.2 beta):
ppc_4xx-ld: section .bootpg [fffff000 -> fffff23b] overlaps section .bss [fffee900 -> fffff8ab]
For many boards, the .bss section is big enough that it wraps around
at the end of the address space (0xFFFFFFFF), so the problem will not
be visible unless you use a 64 bit tool chain for development. On
some boards however, changes to the code size (due to different
optimizations) we bail out with section overlaps like above.
The fix is to add the NOLOAD attribute to the .bss and .sbss
sections, telling the linker that .bss does not consume any space in
the image.

Note: the fixup functions have not been moved to a common place. This
patch is targeted for immediate merging as in solves a build issue, but
the final name/location of the fixups is still subject to debate. I
propose to merge this now, and move the fixups in the next merge window
to be usable by all targets.

Add the ability for modules from the Schindler cm5200 family to use a
single U-Boot image:
- rename cm1_qp1 to cm5200
- add run-time module detection
- parametrize SDRAM configuration according to the module we are running on
Few minor, board-specific fixes included in this patch:
- better MAC address handling
- updated default environment ('update' command uses +{filesize} now)
- improved error messages in the auto-update code
- allow booting U-Boot from RAM (CFG_RAMBOOT)
