This allows DDR configuration to be deferred to the final U-Boot image,
which is able to make use of SPD data.  The SPL itself cannot use SPD due
to code size constraints.  It previously used fixed register values for
DDR configuration, and those values did not work on the p2020rdb-pca
board I tested with.  It's possible that different revisions of the board
require different settings.  Using SPD eliminates that problem.

- Sort by address, and fix column alignment

- Don't label things as localbus that aren't.  Instead, put chipselect
  info at the end of the description for localbus windows.  Note that
  NAND/NOR have their chipselects swapped when booting from NAND, and CS2
  can be either PMC or VSC7385 depending on hwconfig.

- Shrink NAND to the 32K that's actually mapped in the localbus

- Assign an address and size to L2 SRAM.  Remove the similarly named
  but unintelligible "L2 SDRAM(REV.)".

- Remove the untrue comment about L1 stack being mapped with TLB0.

v2: updated for makefile changes earlier in patchset

Some small SPLs do not use nand_base.c, and a subset of those also
require a special driver.  Some SPLs need software ECC but others can't
fit it.

All existing boards that specify CONFIG_SPL_NAND_SUPPORT have these
symbols added to preserve existing behavior.

Update CONFIG_RAMBOOT and CONFIG_NAND_SPL references to accept CONFIG_SPL
and CONFIG_SPL_BUILD, respectively.  CONFIG_NAND_SPL can be removed once
the last mpc85xx nand_spl target is gone.

CONFIG_RAMBOOT will need to remain for other use cases, but it doesn't
seem right to overload it for meaning SPL as well as nand_spl does.  Even
if it's somewhat appropriate for the main u-boot, the SPL itself isn't
(necessarily) ramboot, and we don't have separate configs for SPL and
main u-boot.  It was also inconsistent, as other platforms such as
mpc83xx didn't use CONFIG_RAMBOOT in this way.

It's arch code and not a driver, so move it where it belongs.  When it
originally went into drivers/misc there was no 8xxx CPU directory.

This will make new-SPL support a little easier since we can keep the CPU
stuff together and not need to pull stuff in from drivers/misc.

In the RAMBOOT/SPL case we were creating a TLB entry starting at
CONFIG_SYS_MONITOR_BASE, and just hoping that the base was properly
aligned for the TLB entry size.  This turned out to not be the case
with NAND SPL because the main U-Boot starts at an offset into the image
in order to skip the SPL itself.

Fix the TLB entry to always start at a proper alignment.  We still assume that
CONFIG_SYS_MONITOR_BASE doesn't start immediately before a large-page boundary
thus requiring multiple TLB entries.

This was introduced by commit 24461519, but it
fails in a minimal SPL build where the only thing in arch/powerpc/lib is
cache.c, which apparently doesn't generate any fixup records.

Prabhakar, please test that debug still works.

v2: fixed typo in subject, and explained what the bit does in the changelog

CONFIG_NS16550_MIN_FUNCTIONS is used by small SPLs to gain access to basic
ns16550 output code without pulling in things not needed by the SPL.

This previously only worked with non-MULTI configs.  Recently MULTI was
made mandatory, and MIN_FUNCTIONS fails like this:

drivers/serial/libserial.o: In function `calc_divisor.clone.0':
serial_ns16550.c:(.text.calc_divisor.clone.0+0x24): undefined reference to `get_bus_freq'
drivers/serial/libserial.o: In function `_serial_getc':
(.text._serial_getc+0x30): undefined reference to `NS16550_getc'
drivers/serial/libserial.o: In function `_serial_tstc':
(.text._serial_tstc+0x30): undefined reference to `NS16550_tstc'
drivers/serial/libserial.o: In function `_serial_setbrg':
(.text._serial_setbrg+0x3c): undefined reference to `NS16550_reinit'
make[1]: *** [/tmp/u-boot/spl/u-boot-spl] Error 1
make: *** [/tmp/u-boot/spl/u-boot-spl.bin] Error 2

With MIN_FUNCTIONS we don't need anything from this file, so don't build
it.  The conditional needs to be in the file itself rather than the
makefile, because the config symbols are only imported to the makefiles
once, not separately for the SPL phase of the build.
