Replace enums in ata.h with an include of libata.h
This patch removes some enums from ata.h and replaces them with an

Clean up usage of icache_disable/dcache_disable
There is no point in disabling the icache on 7xx/74xx/86xx parts and not
also flushing the icache. All callers of invalidate_l1_instruction_cache()
call icache_disable() right after. Make it so icache_disable() calls
invalidate_l1_instruction_cache() for us.
Also, dcache_disable() already calls dcache_flush() so there is no point
in the explicit calls of dcache_flush().

Add 'license' command to U-Boot command line
The 'license' command includes the U-Boot license (GPLv2) into the
actual bootloader binary. The license text can be shown interactively
at the U-Boot commandline.
For products where the commandline can actually be accessed by the
end user, this helps to prevent inadvertent GPL violations, since the
GPLv2 license text can no longer be 'forgotten' to be included into
the product.

Update MTD to that of Linux 2.6.22.1
A lot changed in the Linux MTD code, since it was last ported from
Linux to U-Boot. This patch takes U-Boot NAND support to the level
of Linux 2.6.22.1 and will enable support for very large NAND devices
(4KB pages) and ease the compatibility between U-Boot and Linux
filesystems.
This patch is tested on two custom boards with PPC and ARM
processors running YAFFS in U-Boot and Linux using gcc-4.1.2
cross compilers.
MAKEALL ppc/arm has some issues:
* DOC/OneNand/nand_spl is not building (I have not tried porting
these parts, and since I do not have any HW and I am not familiar
with this code/HW I think its best left to someone else.)
Except for the issues mentioned above, I have ported all drivers
necessary to run MAKEALL ppc/arm without errors and warnings. Many
drivers were trivial to port, but some were not so trivial. The
following drivers must be examined carefully and maybe rewritten to
some degree:
cpu/ppc4xx/ndfc.c
cpu/arm926ejs/davinci/nand.c
board/delta/nand.c
board/zylonite/nand.c
