The Sequoia board has two UARTs in "4-pin" mode. This patch modifies the GPIO
configuration to match the schematic, and also sets the SDR0_PFC1 register to
select the corresponding mode for the UARTs.

This patch removes some ft_board_setup() functions from some 4xx boards.
This can be done since we now have a default weak implementation for this
in cpu/ppc4xx/fdt.c. Only board in need for a different/custom
implementation like canyonlands need their own version.

This patch reworks the 440GX interrupt handling so that the common 4xx
code can be used. The 440GX is an exception to all other 4xx variants
by having the cascading interrupt vectors not on UIC0 but on a special
UIC named UICB0 (UIC Base 0). With this patch now, U-Boot references
the 440GX UICB0 when UIC0 is selected. And the common 4xx interrupt
handling is simpler without any 440GX special cases.
Also some additional cleanup to cpu/ppc4xx/interrupt.c is done.

This 2nd patch now removes all UIC mask bit definition. They should be
generated from the vectors by using the UIC_MASK() macro from now on.
This way only the vectors need to get defined for new PPC's.
Also only the really used interrupt vectors are now defined. This makes
definitions for new PPC versions easier and less error prone.
Another part of this patch is that the 4xx emac driver got a little
cleanup, since now the usage of the interrupts is clearer.

This patch is the first step to consolidate the UIC related defines in the

steps.

This patch disables the square wave output of the M41T62 RTC used on
Canyonlands & Glacier. Here the explanation:
The serial real-time clock part used in the design is an
STMicro M41T62. This part has a full-time 32KHz square wave
output that is connected to the TmrClk input to the
processor. The default state for this square wave output is
enabled so the output runs continuously when the board is
powered normally and also from the battery. The TmrClk input
to the processor goes to ground when the power is removed
from the board/processor, and therefore the running square
wave output is driving ground which drains the battery quickly.

This patch changes the return type of initdram() from long int to phys_size_t.
This is required for a couple of reasons: long int limits the amount of dram
to 2GB, and u-boot in general is moving over to phys_size_t to represent the
size of physical memory. phys_size_t is defined as an unsigned long on almost
all current platforms.
This patch *only* changes the return type of the initdram function (in
include/common.h, as well as in each board's implementation of initdram). It
does not actually modify the code inside the function on any of the platforms;
platforms which wish to support more than 2GB of DRAM will need to modify
their initdram() function code.
Build tested with MAKEALL for ppc, arm, mips, mips-el. Booted on powerpc
MPC8641HPCN.

This patch series unifies the AMCC eval board ports by introducing
a common include header for all AMCC eval boards:
include/configs/amcc-common.h
This header now includes all common configuration options/defines which
are removed from the board specific headers.
The reason for this is ease of maintenance and unified look and feel
of all AMCC boards.

This patch gets rid of the spi_chipsel table and adds a handful of new
functions that makes the SPI layer cleaner and more flexible.
Instead of the spi_chipsel table, each board that wants to use SPI
gets to implement three hooks:
* spi_cs_activate(): Activates the chipselect for a given slave
* spi_cs_deactivate(): Deactivates the chipselect for a given slave
* spi_cs_is_valid(): Determines if the given bus/chipselect
combination can be activated.
Not all drivers may need those extra functions however. If that's the
case, the board code may just leave them out (assuming they know what
the driver needs) or rely on the linker to strip them out (assuming
--gc-sections is being used.)
To set up communication parameters for a given slave, the driver needs
to call spi_setup_slave(). This returns a pointer to an opaque
spi_slave struct which must be passed as a parameter to subsequent SPI
calls. This struct can be freed by calling spi_free_slave(), but most
driver probably don't want to do this.
Before starting one or more SPI transfers, the driver must call
spi_claim_bus() to gain exclusive access to the SPI bus and initialize
the hardware. When all transfers are done, the driver must call
spi_release_bus() to make the bus available to others, and possibly
shut down the SPI controller hardware.
spi_xfer() behaves mostly the same as before, but it now takes a
spi_slave parameter instead of a spi_chipsel function pointer. It also
got a new parameter, flags, which is used to specify chip select
behaviour. This may be extended with other flags in the future.
This patch has been build-tested on all powerpc and arm boards
involved. I have not tested NIOS since I don't have a toolchain for it
installed, so I expect some breakage there even though I've tried
fixing up everything I could find by visual inspection.
I have run-time tested this on AVR32 ATNGW100 using the atmel_spi and
DataFlash drivers posted as a follow-up. I'd like some help testing
other boards that use the existing SPI API.
But most of all, I'd like some comments on the new API. Is this stuff
usable for everyone? If not, why?
Changed in v4:
- Build fixes for various boards, drivers and commands
- Provide common struct spi_slave definition that can be extended by
drivers
- Pass a struct spi_slave * to spi_cs_activate and spi_cs_deactivate
- Make default bus and mode build-time configurable
- Override default SPI bus ID and mode on mx32ads and imx31_litekit.
Changed in v3:
- Add opaque struct spi_slave for controller-specific data associated
with a slave.
- Add spi_claim_bus() and spi_release_bus()
- Add spi_free_slave()
- spi_setup() is now called spi_setup_slave() and returns a
struct spi_slave
- soft_spi now supports four SPI modes (CPOL|CPHA)
- Add bus parameter to spi_setup_slave()
- Convert the new i.MX32 SPI driver
- Convert the new MC13783 RTC driver
Changed in v2:
- Convert the mpc8xxx_spi driver and the mpc8349emds board to the
new API.

Historically the 405 U-Boot port had a dram_init() call in early init
stage. This function was still called from start.S and most of the time
coded in assembler. This is not needed anymore (since a long time) and
boards should implement the common initdram() function in C instead.
This patch now removed the dram_init() call from start.S and removes the
empty implementations that are scattered through most of the 405 board
ports. Some older board ports really implement this dram_init() though.
These are:
csb272
csb472
ERIC
EXBITGEN
W7OLMC
W7OLMG
I changed those boards to call this assembler dram_init() function now
from their board specific initdram() instead. This *should* work, but please
test again on those platforms. And it is perhaps a good idea that those
boards use some common 405 SDRAM initialization code from cpu/ppc4xx at
some time. So further patches welcome here.

This patch (Part 2 of 2):
* Rolls up a suite of changes to enable correct primordial stack and
global data handling when the data cache is used for such a purpose
for PPC40x-variants (i.e. CFG_INIT_DCACHE_CS).
* Related to the first, unifies DDR2 SDRAM and ECC initialization by
eliminating redundant ECC initialization implementations and moving
redundant SDRAM initialization out of board code into shared 4xx
code.
* Enables MCSR visibility on the 405EX(r).
* Enables the use of the data cache for initial RAM on
both AMCC's Kilauea and Makalu and removes a redundant
CFG_POST_MEMORY flag from each board's CONFIG_POST value.
- Removed, per Stefan Roese's request, defunct memory.c file for
Makalu and rolled sdram_init from it into makalu.c.
With respect to the 4xx DDR initialization and ECC unification, there
is certainly more work that can and should be done (file renaming,
etc.). However, that can be handled at a later date on a second or
third pass. As it stands, this patch moves things forward in an
incremental yet positive way for those platforms that utilize this
code and the features associated with it.

When SATA is selected (via jumper J6) we need to disable the first PCIe
node in the device tree, so that Linux doesn't initialize it. Otherwise
the Linux SATA driver will fail to detect the devices.
The same goes the other way around too. So if PCIe is selected we need
to disable the SATA node in the device tree.
This is because PCIe port 0 and SATA on 460EX share the same pins
(multiplexed) and we have to configure in U-Boot which peripheral is
enabled.

This patch adds fdt (flattened device tree) support to the AMCC
Acadia eval board. This increases the image size and it doesn't
fit anymore into 256kByte. Since we didn't want to remove features
from the configuration, we decided to increase the U-Boot image size
(add one flash sector).
Also changed the default environment definition to make it
independent of such changes.

460EX doesn't support a fixed bootstrap option to boot from 512 byte page
NAND devices. The only bootstrap option for NAND booting is option F for
2k page devices. So to boot from a 512 bype page device, the I2C bootstrap
EEPROM needs to be programmed accordingly.
This patch adds basic NAND booting support for the AMCC Canyonlands aval
board and also adds support to the "bootstrap" command, to enable NAND
booting I2C setting.
Tested with 512 byte page NAND device (32MByte) on Canyonlands.
