This change has 3 goals:
- Have secondary cores be released into spin loops at their 'true'
  address in SDRAM.  Previously, secondary cores were put into spin
  loops in the 0xfffffxxx address range which required that boot page
  translation was always enabled while cores were in their spin loops.

- Allow the TLB window that the primary core uses to access the
  secondary cores boot page to be placed at any address.  Previously, a
  TLB window at 0xfffff000 was always used to access the seconary cores'
  boot page.  This TLB address requirement overlapped with other
  peripherals on some boards (eg XPedite5370).  By default, the boot
  page TLB will still use the 0xfffffxxx address range, but this can be
  overridden on a board-by-board basis by defining a custom
  CONFIG_BPTR_VIRT_ADDR.  Note that the TLB used to map the boot page
  remains in use while U-Boot executes.  Previously it was only
  temporarily used, then restored to its initial value.

- Allow Boot Page Translation to be disabled on bootup.  Previously,
  Boot Page Translation was always left enabled after secondary cores
  were brought out of reset.  This caused the 0xfffffxxx address range
  to somewhat "magically" be translated to an address in SDRAM.  Some
  boards may not want this oddity in their memory map, so defining
  CONFIG_MPC8xxx_DISABLE_BPTR will turn off Boot Page Translation after
  the secondary cores are initialized.

These changes are only applicable to 85xx boards with CONFIG_MP defined.

When QorIQ based board is configured as a PCIe agent, then unlock/enable
inbound PCI configuration cycles and init a 4K inbound memory window;
so that a PCIe host can access the PCIe agents SDRAM at address 0x0

Currently fdt_fixup_stdout() is using hard-coded CONFIG_CONS_INDEX
constant. With multi-serial support, the CONS_INDEX may no longer
represent actual console, so we should try to extract port number
from the current stdio device name instead of always hard-coding the
constant value.

Its possible that we end up with a device tree that happens to be a
particular size that after we call fdt_resize() we don't have any
space left for the initrd mem_rsv.

Fix this be adding a second mem_rsv into the size calculation.  We
had one to cover the fdt itself and we have the potential of adding
a second for the initrd.

introduced in commit f772acf8. This
turns out to be caused by a stack alignment issue. The armv5te

Start of support of
Texas Instruments Software Development Platform(SDP)
for OMAP3430 - SDP3430

Highlights of this platform are:
Flash Memory devices:
	Sibley NOR, Micron 8bit NAND and OneNAND
Connectivity:
	3 UARTs and expanded 4 UART ports + IrDA
	Ethernet, USB
Other peripherals:
	TWL5030 PMIC+Audio+Keypad
	VGA display
Expansion ports:
	Memory devices plugin boards (PISMO)
	Connectivity board for GPS,WLAN etc.
Completely configurable boot sequence and device mapping
etc.

Support default jumpering and:
 - UART1/ttyS0 console(legacy sdp3430 u-boot)
 - UART3/ttyS2 console (matching other boards,
		 and SDP HW docs)
 - Ethernet
 - mmc0
 - NOR boot

Currently the UART1 is enabled by default.  for
compatibility with other OMAP3 u-boot platforms,
enable the #define of CONSOLE_J9.

Conflicts:

	Makefile

Fixed the conflict with smdkc100_config by moving omap_sdp3430_config
to it is alphabetically sorted location above zoom1.

Due to new TI boards being added to U-Boot, the hardware.h

the EMIF addresses being redefined.

The long term solution(after 2009.11) to this is to

This patch removes the Sequoia "bootstrap" command and replaces it
with the now common command "chip_config".

Please note that the patches with the dynamic PCI sync clock
configuration have to be applied, before this one should go in.
This is because Sequoia has 2 different bootstrap EEPROMs, and
the old bootstrap command configured different values depending
on the detected PCI async clock (33 vs. 66MHz). With the PCI sync
clock patches, this is not necessary anymore. The PCI sync clock
will be configured correctly on-the-fly now.

Some 4xx variants (e.g. 440EP(x)/GR(x)) have an internal
synchronous PCI clock. Knowledge about the currently configured
value might be helpful. So let's print it out upon bootup.

PPC440EP(x)/PPC440GR(x):
In asynchronous PCI mode, the synchronous PCI clock must meet
certain requirements. The following equation describes the
relationship that must be maintained between the asynchronous PCI
clock and synchronous PCI clock. Select an appropriate PCI:PLB
ratio to maintain the relationship:

AsyncPCIClk - 1MHz <= SyncPCIclock <= (2 * AsyncPCIClk) - 1MHz

This patch now adds a function to check and reconfigure the sync
PCI clock to meet this requirement. This is in preparation for
some AMCC boards (Sequoia/Rainier and Yosemite/Yellowstone) using this
function to not violate the PCI clocking rules.

Till now only the ranges in the ebc node are updated with the values
currently configured in the PPC4xx EBC controller. With this patch now
the NOR flash size is updated in the device tree blob as well. This is
done by scanning the compatible nodes "cfi-flash" and "jedec-flash"
for the correct chip select number.

This size fixup is enabled for all AMCC eval board right now. Other
4xx boards may want to enable it as well, if this problem with multiple
NOR FLASH sizes exists.
