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)

All other u-boot architectures have an include/asm/errno.h, so
this change adds it to the mips include/asm-mips headers also.

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.)

to configure the HMATRIX for boards with special needs, and add new

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.
