PXA USB OHCI: "usb stop" implementation.
Some USB keys need to be switched off before loading the kernel
otherwise they can remain in an undefined status which prevents them
to be correctly recognized by the kernel.

ppc4xx: Fix bug in I2C bootstrap values for Sequoia/Rainier
The I2C bootstrap values that can be setup via the "bootstrap" command,
were setup incorrect regarding the generation of the internal sync PCI
clock. The values for PLB clock == 133MHz were slighly incorrect and the
values for PLB clock == 166MHz were totally incorrect. This could
lead to a hangup upon booting while PCI configuration scan.
This patch fixes this issue and configures valid PCI divisor values
for the sync PCI clock, with respect to the provided external async
PCI frequency.
Here the values of the formula in the chapter 14.2 "PCI clocking"
from the 440EPx users manual:
The BCSR status bit for the 66MHz PCI operation was correctly
addressed (MSB/LSB problem). Now the correct currently setup
PCI frequency is displayed upon bootup.
This patch also fixes this problem on Rainier & Yellowstone, since these
boards use the same souce code as Sequoia & Yosemite do.
CFG_MEMTEST_START uses weird magic involving gd, which fails to
compile. Use hardcoded values instead (we actually know how much RAM
we have on board.)

Fpga: fix incorrect test of CFG_FPGA_XILINX macro
CFG_FPGA_XILINX is a bit value used to test against the value in
CONFIG_FPGA. Testing for a value will always return TRUE. I don't
think that is the intention in this code.

Bugfix: remove embedded null (\0) from CFG_BOOTFILE macro in TQM8540_config
/bin/bash and /bin/dash (which /bin/sh is linked to on ubuntu) handle embedded
nulls in a string differently. For example, the following statement:
echo "this is a string\0" > afile
Will produce the following with /bin/bash:
"this is a string\0"
But with /bin/dash, will produce:
"this is a string
Bug fixed by moving the embedded null out of the makefile and into the
config header. Also renamed the macro to avoid usage colision with the same
macro used by other board ports.

MCC200: fix build warning
The MCC200 board config file includes version.h for some customer-
specific setting, which causes warnings with "make depend"; build
version.h before depend.
Updates to atstk1002 U-Boot header file:
- Changed bootargs:
* Set the bootargs for at1002 to point to the SD-card partition instead
* ... of the boot flash.
* Removing the rootfstype since that argument are not needed.
This patch applies some clarifying comments to how the different
clocks are setup according to atstk1002.h Some of the previous
comments where stating wrongful information.

TQM8xx[LM]: Fix broken environment alignment.
With recent toolchains, the environment sectors were no longer aligned to
sector boundaries. The reason was a combination of two bugs:
1) common/environment.c assumed that CONFIG_TQM8xxL would be defined
for all TQM8xxL and TQM8xxM boards. But "include/common.h", where
this gets defined, is not included here (and cannot be included
without causing lots of problems).
Added a new #define CFG_USE_PPCENV for all boards which really
want to put the environment is a ".ppcenv" section.
2) The linker scripts just include environment.o, silently assuming
that the objects in that file are really in the order in which
they are coded in the C file, i. e. "environment" first, then
"redundand_environment", and "env_size" last. However, current
toolchains (GCC-4.x) reorder the objects, causing the environment
data not to start on a flash sector boundary:
Note: this patch fixes just the first part, and cures the alignment
problem by making sure that "env_size" gets placed correctly. However,
we still have a potential issue because primary and redundant
environment sectors are actually swapped, i. e. we have now:
Fix usage of do_div() in nand erase|read|write process output.
The last patch to nand_util.c introduced do_div() instead of libgcc's
implementation. But do_div() returns the quotient in its first
macro parameter and not as result.
This config option sets the default for the progress information
output behavior that can also be configured through the 'quiet'
environment variable.
The legacy NAND code does not print the current progress info
on the console. So this option is for backward compatibility for
units that are in the field and where setting the quiet variable
is not an option. With CFG_NAND_QUIET set to '1' the console
progress info is turned off. This can still be overwritten
through the environment variable.

behind the primary host/PCIe
- 'pciscandelay' env variable is recognized to allow for user-controlled

- correct configuration space mapping
- correct bus numbering
- better access to config space
Prior to this patch, the 440SPe host/PCIe bridge was able to configure only the
first device on the first bus. We now allow to configure up to 16 buses;
also, scanning for devices behind the PCIe-PCIe bridge is supported, so
peripheral devices farther in hierarchy can be identified.

Convert using fixup mechanism to suppressing MCK for the duration of config
read/write transaction: while fixups work fine with the case of a precise
exception, we identified a major drawback with this approach when there's
an imprecise case. In this scenario there is the following race condition:
the fixup is (by design) set to catch the instruction following the one
actually causing the exception; if an interrupt (e.g. decrementer) happens
between those two instructions, the ISR code is executed before the fixup
handler the machine check is no longer protected by the fixup handler as it
appears as within the ISR code. In consequence the fixup approach is being
phased out and replaced with explicit suppressing of MCK during a PCIe
config read/write cycle.
