All implementations of the functions i2c_reg_read() and
i2c_reg_write() are identical. We can save space and simplify the
code by converting these functions into inlines and putting them in
i2c.h.

Add a library that helps in translating between virtual and physical
addresses. This library can be useful as a simple means to implement
map_physmem() and virt_to_phys() for platforms that need functionality
beyond the simple 1:1 mapping.
Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
virt_to_phys() returns the physical address given a virtual. In most
cases this will be just the input value as the vast majority of
systems run in a 1:1 mode.
However in systems that are not running this way it should report the
physical address or ~0 if no mapping exists for the given virtual
address.

FDT support is used for both FIT style images and for architectures
that can pass a fdt blob to an OS (ppc, m68k, sparc).
For other architectures and boards which do not pass a fdt blob to an
OS but want to use the new uImage format, we just need FIT support.
Now we can have the 4 following configurations :
1) FIT only CONFIG_FIT
2) fdt blob only CONFIG_OF_LIBFDT
3) both CONFIG_OF_LIBFDT & CONFIG_FIT
4) none none

This patch now adds a flush to the data cache upon relocation. The
current implementation is missing this. Only a comment states that it
should be done. So let's really do it now.

This patch adds the CONFIG_SKIP_LOWLEVEL_INIT option to start.S. This
enables support for boards where the lowlevel initialization is
already done when U-Boot runs (e.g. via OnChip ROM).
This will be used in the upcoming VCTH board support.

This patch adds the board_early_init_f() call to the MIPS init

Microblaze platforms use generic settings and to have
many platforms is confusing that's why I decided to remove this
platform from U-BOOT. ml401 tree is sufficient for covering
all Microblaze platforms.
This change will go through microblaze custodian tree.
While the doc/README.NetConsole does have a snippet for people to
create their own netcat script, it's a lot easier to make a simple
dedicated script and tell people to use it.
Also spruce it up a bit to make it user friendly.

As we moved data_crc() invocation from jffs2_1pass_build_lists() to
jffs2_1pass_read_inode() data_crc is going to be calculated on each
inode access. This patch adds caching of data_crc() results. There
is no significant improvement in speed (because of flash access
caching added in previous patch I think, crc in RAM is really fast)
but this patch impacts memory usage -- every b_node structure uses
12 bytes instead of 8.
