Some boards need to set things up before the debug UART can be used. On
these boards a call to debug_uart_init() is insufficient. When this option
is enabled, the function board_debug_uart_init() will be called when
debug_uart_init() is called. You can put any code here that is needed to
set up the UART ready for use, such as set pin multiplexing or enable
clocks.

We want to be able to add other common code to this function. So change the

Currently struct fmap_entry is used to describe a mrc region.
However this structure contains some other fields that are not
related to mrc cache and causes confusion. Besides, it does not
include a base address field to store SPI flash's base address.
Instead in the mrccache.c it tries to use CONFIG_ROM_SIZE to
calculate the SPI flash base address, which unfortunately is
not 100% correct as CONFIG_ROM_SIZE may not match the whole
SPI flash size.
Define a new struct mrc_region and use it instead.

This adds mrccache_reserve(), mrccache_get_region() and
mrccache_save() APIs to the mrccache codes. They are ported
from the ivybridge implementation, but with some changes.
For example, in the mrccache_reserve(), ivybridge version
only reserves the pure MRC data, which causes additional
malloc() when saving the cache as the save API needs some
meta data. Now we change it to save the whole MRC date plus
the meta data to elinimate the need for the malloc() later.

So far VxWorks bootline can be contructed from various environment
variables, but when these variables do not exist we get these from
corresponding config macros. This is not helpful as it requires
rebuilding U-Boot, and to make sure these config macros take effect
we should not have these environment variables. This is a little
bit complex and confusing.
Now we change the logic to always contruct the bootline from
environments (the only single source), by adding two new variables
"bootdev" and "othbootargs", and adding some comments about network
related settings mentioning they are optional. The doc about the
bootline handling is also updated.
