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.

Spotted by Dean Capindale.
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.

* 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.
* include/asm/bitops.h:302: warning: '__swab32p' is static but used in
inline function 'ext2_find_next_zero_bit' which is not static

Currently, END_OF_RAM is used by the trap code to determine if
we should attempt to access the stack pointer or not. However,
on systems with a lot of RAM, only a subset of the RAM is
guaranteed to be mapped in and accessible. Change END_OF_RAM
to use get_effective_memsize() instead of using the raw ram
size out of the bd.

If common.h isn't first we can get CONFIG_ options defined in the
board config file ignored. This can cause an issue if any of those
config options impact the size of types of data structures
(eg CONFIG_PHYS_64BIT).

This function prints the values of all the BAT register
pairs - I needed this for debug earlier this week; adding it to
lib_ppc so others can use it (and add it to reginfo commands
if so desired).

Currently, this code only deals with BATs 0-3, which makes
it useless on systems that support BATs 4-7. Add the

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)

For NAND erase sizes smaller than one NAND erase block, erase
percentage output becomes grater than 100% e.g.
-- cut --
> nand info
Device 0: NAND 64MiB 1,8V 8-bit, sector size 16 KiB
> nand erase 0x100000 0x2000
NAND erase: device 0 offset 0x100000, size 0x2000
Erasing at 0x100000 -- 200% complete.
OK
>
-- cut --
Correct this and give user a warning that more is erased than specified:
-- cut --
> nand erase 0x100000 0x2000
NAND erase: device 0 offset 0x100000, size 0x2000
Warning: Erase size 0x00002000 smaller than one erase block 0x00004000
Erasing 0x00004000 instead
Erasing at 0x100000 -- 100% complete.
OK

Those days, nand.h contains a reference to the array, so there is
no need to declare it elsewhere.

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.

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.)

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.

annotations.

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
