SMDK6400 can only boot U-Boot from NAND-flash. This patch adds a nand_spl
driver for it too. The board can also boot from the NOR flash, but due to
hardware limitations it can only address 64KiB on it, which is not enough
for U-Boot. Based on the original sources by Samsung for U-Boot 1.1.6.
Notice: USB on S3C6400 currently works _only_ with switched off MMU. One could
try to enable the MMU, but map addresses 1-to-1, and disable data cache, then
it should work too and we could still profit from instruction cache.

ARM DaVinci: Changing function names for EMAC driver
DM644x is just one of a series of DaVinci chips that use the EMAC driver.
By replacing all the function names that start with dm644x_* to davinci_*
we make these function more portable. I have tested this change on my EVM.
DM6467 is another DaVinci SOC which uses the EMAC driver and i will
be sending patches that add DaVinci DM6467 support to the list soon.
- memsetup.s is changed/merged to lowlevel_init.S
memsetup.S has a global label memsetup that just returns back to caller
- memsetup global label is changed/merged to lowlevel_init
This label is not called from anywhere.

The main purpose of this rewrite it to be able to share the same
initialization code on all FSL PowerPC products that have DDR
controllers. (83xx, 85xx, 86xx).
The code is broken up into the following steps:
GET_SPD
COMPUTE_DIMM_PARMS
COMPUTE_COMMON_PARMS
GATHER_OPTS
ASSIGN_ADDRESSES
COMPUTE_REGS
PROGRAM_REGS
This allows us to share more code an easily allow for board specific code

Additionally this code base adds support for >4G of DDR and provides a
foundation for supporting interleaving on processors with more than one

libfdt: Implement fdt_get_property_namelen() and fdt_getprop_namelen()
As well as fdt_subnode_offset(), libfdt includes an
fdt_subnode_offset_namelen() function that takes the subnode name to
look up not as a NUL-terminated string, but as a string with an
explicit length. This can be useful when the caller has the name as
part of a longer string, such as a full path.
However, we don't have corresponding 'namelen' versions for
fdt_get_property() and fdt_getprop(). There are less obvious use
cases for these variants on property names, but there are
circumstances where they can be useful e.g. looking up property names
which need to be parsed from a longer string buffer such as user input
or a configuration file, or looking up an alias in a path with
IEEE1275 style aliases.
So, since it's very easy to implement such variants, this patch does
so. The original NUL-terminated variants are, of course, implemented
in terms of the namelen versions.
