9b124a6834 MPC512x: Change traps.c to not reference non-addressable memory
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.

81673e9ae1 Make sure common.h is the first include.
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).

d5b9b8cdb8 PPC: Add print_bats() to lib_ppc/bat_rw.c

Change all code that conditionally operates on high bat
registers (that is, BATs 4-7) to look at CONFIG_HIGH_BATS

enabled)

9723bbb46a nand: Correct NAND erase percentage output
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

a8092c021d avr32: Fix theoretical race in udelay()
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.

caf83ea888 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.)
