TQM5200: fix spurious characters on second serial interface
With this patch PSC3 is configured as UART. This is done, because if
the pins of PSC3 are not configured at all (-> all pins are GPI),
due to crosstalk, spurious characters may be send over the RX232_2_TXD
signal line.

TQM5200S: fix commands for STK52xx base board because of missing SM501 grafic controller
Some commands for the STK52xx base board try to access the SM501 grafic

fix pxa255_idp board
The pxa255_idp being an old unmaintained board showed several issues:
1. CONFIG_INIT_CRITICAL was still defined.
2. Neither CONFIG_MAC_PARTITION nor CONFIG_DOS_PARTITION was defined.
3. Symbol flash_addr was undeclared.
4. The boards lowlevel_init function was still called memsetup.
5. The TEXT_BASE was still 0xa3000000 rather than 0xa3080000.
6. Using -march=armv5 instead of -march=armv5te resulted in lots of
'target CPU does not support interworking' warnings on recent compilers.
7. The PXA's serial driver redefined FFUART, BTUART and STUART used as
indexes rather than the register definitions from the pxa-regs header
file. Renamed them to FFUART_INDEX, BTUART_INDEX and STUART_INDEX to
avoid any ambiguities.
8. There were several redefinition warnings concerning ICMR, OSMR3,
OSCR, OWER, OIER, RCSR and CCCR in the PXA's assembly start file.
9. The board configuration file was rather outdated.
10. The part header file defined the vendor, product and revision arrays
as unsigned chars instead of just chars in the block_dev_desc_t
structure.
Now we load $gp with _GLOBAL_OFFSET_TABLE_, but this is incorrect use.
As a general principle, we should use _gp for $gp.
Thanks to linker script's help we fortunately have _gp which equals to
_GLOBAL_OFFSET_TABLE_. But once _gp gets out of alignment, we will not
be able to access to GOT entires, global variables and procedure entry
points. The right thing to do is to use _gp.
This patch also introduce a new symbol `.gpword _GLOBAL_OFFSET_TABLE_'
which holds the offset from _gp. When updating GOT entries, we use this
offset and _gp to calculate the final _GLOBAL_OFFSET_TABLE_.
This patch is originally submitted by Vlad Lungu <vlad@comsys.ro>, then
I made some change to leave over num_got_entries.

Improve handling of PCI interrupt device tree fixup on MPC85xx CDS
On the MPC85xx CDS we have two issues:
1. The device tree fixup code did not check to see if the property we are
trying to update is actually found. Its possible that it would update
random memory starting at 0.
2. Newer Linux kernel's have moved the location of the PCI nodes to be
sibilings of the soc node and not children. The explicit PATH to the PCI
node would not be found for these device trees. Add the ability to handle
both paths. In the future we shouldn't handle such fixups by explicit path.

86xx: Allow for fewer DDR slots per memory controller.
As a direct correlation exists between DDR DIMM slots

configuration read or not.
Effectively, this now allows for 1 or 2 DIMM slots

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_MAMR_PTA changes from 39 to 97. This result

Bugfix: Use only one PTD for one endpoint
Original isp116x-hcd code prepared multiple PTDs for longer than 16
byte transfers for one endpoint. That is unnecessary because the
ISP116x is able to split long data from one PTD into multiple
transactions based on the buffer size of the endpoint. It also caused
serious problems if the endpoint NAKed some of the transactions. In
that case ISP116x wouldn't notice that the other PTDs were for the same
endpoint and would try the other PTDs possibly out of order. That would
break the whole transfer.
This patch makes isp116x_submit_job to use one PTD for one transfer.
