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.
Systems that support open-drain GPIO properly are allowed provide an
empty I2C_TRISTATE define. However, this means that we need to be
careful not to drive SDA low when the slave is expected to respond.
This patch adds a missing I2C_SDA(1) to read_byte() required to
tristate the SDA line on systems that support open-drain GPIO.

If the specified delay is very short, the cycle counter may go past the
"end" time we are waiting for before we get around to reading it.
Fix it by checking the different between the cycle count "now" and the
cycle count at the beginning. This will work as long as the delay
measured in number of cycles is below 2^31.
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.
avr32: Use the same entry point for reset and exception handling
Since the reset vector is always aligned to a very large boundary, we
can save a couple of KB worth of alignment padding by placing the
exception vectors at the same address.
Deciding which one it is is easy: If we're handling an exception, the
CPU is in Exception mode. If we're starting up after reset, the CPU is
in Supervisor mode. So this adds a very minimal overhead to the reset
path (only executed once) and the exception handling path (normally
never executed at all.)
All C code is compiled with -ffunction-sections -fdata-sections.
Assembly functions should get their own sections as well so that
everything looks consistent.
avr32: Rename pm_init() as clk_init() and make SoC-specific
pm_init() was always more about clock initialization than anything
else. Dealing with PLLs, clock gating and such is also inherently
SoC-specific, so move it into a SoC-specific directory.
Rework the HMATRIX configuration interface so that it becomes easier
to configure the HMATRIX for boards with special needs, and add new
parts.
The HMATRIX header file has been split into a general,
chip-independent part with register definitions, etc. and a
chip-specific part with SFR bitfield definitions and master/slave
identifiers.
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.
Remove it on STK1000 as well, and get rid of all the associated code and
annotations.

ppc4xx: Canyonlands: Disable PCIe0/SATA in dev-tree depending on selection
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.
