This is a re-write of the NAND FSL UPM driver using the more universal
hwcontrol callback (instead of the cmdfunc callback). Here is a brief
list of furher modifications:
- For the time being, the UPM setup writing the UPM array has been
removed from the driver and must now be done by the board specific
code.
- The bus width definition in "struct fsl_upm_nand" is now in bits to
comply with the corresponding Linux driver and 8, 16 and 32 bit
accesses are supported.
- chip->dev_read is only set if fun->dev_ready != NULL, which is
required for boards not connecting the R/B pin.
- A few issue have been fixed with MxMR bit manipulation like in the
corresponding Linux driver.
Note: I think the "io_addr" field of "struct fsl_upm" could be removed
as well, because the address is already determined by
"nand->IO_ADDR_[RW]", but I'm not 100% sure.
This patch has been tested on a TQM8548 modules with the NAND chip
Micron MT29F8G08FABWP.
This patch is based on the following patches posted to this list a few
minutes ago:

83xx/85xx/86xx: add more MxMR local bus definitions

PPC: add accessor macros to clear and set bits in one shot
This patch adds macros from linux/include/asm-powerpc/io.h to clear and
set bits in one shot using the in_be32, out_be32, etc. accessor functions.
They are very handy to manipulate bits it I/O registers.
This patch is required for my forthcoming FSL NAND UPM driver re-write and
the support for the TQM8548 module.

83xx/85xx/86xx: add more MxMR local bus definitions
This patch adds more macro definitions for the UPM Machine Mode Registers
They are copied from "include/mpc82xx.h" to simplify the merge of all 8xxx
common local bus definitions into include/asm-ppc/fsl_lbc.h. They are
required for my forthcoming FSL NAND UPM driver re-write and the support
for the TQM8548 module.
This patch is based on the following two patches from Anton Vorontsov:

Merge mpc85xx.h's LBC defines to fsl_lbc.h. Also, adopt ACS names
from mpc85xx.h, so ACS_0b10 renamed to ACS_DIV4, ACS_0b11 to ACS_DIV2.

The current cpu identification code is used just to return the name
of the processor at boot. There are some other locations that the name
is useful (device tree setup). Expose the functionality to other bits
of code.
Also, drop the 'E' suffix and add it on by looking at the SVR version
when we print this out. This is mainly to allow the most flexible use
of the name. The device tree code tends to not care about the 'E' suffix.

This adds a new SPI flash subsystem.

but some preliminary support for other flash types is in place as
well.

This adds a driver for the SPI controller found on most AT91 and AVR32
chips, implementing the new SPI API.
Changed in v4:
- Update to new API
- Handle zero-length transfers appropriately. The user may send a
zero-length SPI transfer with SPI_XFER_END set in order to
deactivate the chip select after a series of transfers with chip
select active. This is useful e.g. when polling the status
register of DataFlash.

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.

AVR32 and AT91SAM9 both have their own identical definitions of
container_of() taken from the Linux kernel. Move it to common.h so
that all architectures can use it.
container_of() is already used by some drivers, and will be used
extensively by the new and improved SPI API.

* The cfi_flash.c memset fix actual allows the board to boot so there is
a bit more going on here than just resolving warnings associated with
uninitialized variables.

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.

The .flashprog section was only needed back when we were running
directly from flash, and it's even more useless on NGW100 since it
uses the CFI flash driver which never used this workaround in the
first place.

annotations.
