Make it so we keep track of which LAWs have allocated and provide
a function (set_next_law) which can allocate a LAW for us if one is
free.
In the future we will move to doing more "dynamic" LAW allocation
since the majority of users dont really care about what LAW number
they are at.
Also, add CONFIG_MPC8540 or CONFIG_MPC8560 to those boards which needed them

A number of board ports have empty version of board_early_init_f
for no reason since we control its via CONFIG_BOARD_EARLY_INIT_F.

Some TQM85xx boards could be equipped with up to 1 GiB (NOR) Flash
memory. The current memory map only supports up to 128 MiB Flash.
This patch adds the configuration option CONFIG_TQM_BIGFLASH. If
set, up to 1 GiB flash is supported. To achieve this, the memory
map has to be adjusted in great parts (for example the CCSRBAR is
moved from 0xE0000000 to 0xA0000000).
If you want to boot Linux with CONFIG_TQM_BIGFLASH set, the new
memory map also has to be considered in the kernel (changed
CCSRBAR address, changed PCI IO base address, ...). Please use
an appropriate Flat Device Tree blob (tqm8548.dtb).

This patch adds support for NAND FLASH on the TQM8548. It is disabled by
default and can be enabled for the TQM8548 modules. It is now based on
the re-written FSL NAND UPM driver. A patch has been posted earlier today
with the subject:
"NAND FSL UPM: driver re-write using the hwcontrol callback"
Note that the R/B pin is not supported by that module requiring to use
the specified maximum delay time.
Note: With NAND support enabled the size of the U-Boot image exceeds
256 KB and TEXT_BASE must therefore be set to 0xfff80000 in config.mk,
doubling the image size :-(.

This patch adds basic support for the TQM8548 module from TQ-Components
(http://www.tqc.de/) including DDR2 SDRAM initialisation and support for
eTSEC 3 and 4
Furthermore Flash buffer write has been enabled to speed up output to
the Flash by approx. a factor of 10.

The 'N' type Spansion flashes (S29GLxxxN series) have bigger sectors,
than the formerly used 'M' types (S29GLxxxM series), so the flash layout
needs to be changed -> new start address of the environment. The macro
definition CONFIG_TQM_FLASH_N_TYPE is undefined by default and must be
defined for boards with 'N' type flashes.

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.

Change all code that conditionally operates on high bat
registers (that is, BATs 4-7) to look at CONFIG_HIGH_BATS
instead of the myriad ways this is done now. Define the option
for every config for which high bats are supported (and
enabled by early boot, on parts where they're not always
enabled)

This cleans up the SDRAM initialization and related code a bit, and
allows faster booting.
* Add definitions for EBI and internal SRAM to asm/arch/memory-map.h
* Remove memory test from sdram_init() and make caller responsible
for verifying the SDRAM and determining its size.
* Remove base_address member from struct sdram_config (was sdram_info)
* Add data_bits member to struct sdram_config and kill CFG_SDRAM_16BIT
* Add support for a common STK1000 hack: 16MB SDRAM instead of 8.

Make STK1002 and NGW100 boards act more alike:
- STK boards can use as many arguments as NGW
- STK boards don't need to manage FPGAs either
- NGW commands should match STK ones
