4b7e3d045c Blackfin: move default boot SPI CS to common code
Move the default SPI CS that we boot from into common code so that it can
be used in other SPI drivers and environment settings.

f790ef6ff1 Blackfin: dynamically update UART speed when initializing
Previously, booting over the UART required the baud rate to be known ahead
of time.  Using a bit of tricky simple math, we can calculate the new board
rate based on the old divisors.

just the slow one.  If the functionality is available, then use it.

09dc6b0bbd Blackfin: use on-chip syscontrol() rom function when available
Newer Blackfin's have an on-chip rom with a syscontrol() function that needs
to be used to properly program the memory and voltage settings as it will
include (possibly critical) factory tested bias values.

28745db969 jedec_flash: Only use manufacturer defines from common flash.h
This patch removes the double defined manufacturer defines from
jedec_flash.c. Since the common defines in flash.h are 32bit
we now need the (16) cast. This patch also removes the compilation
warning (e.g. seen on hcu5):

09ce9921a7 flash/cfi_flash: Use virtual sector start address, not phys
include/flash.h was commented to say that the address in
flash_info->start was a physical address.  However, from u-boot's
point of view, and looking at most flash code, it makes more
sense for this to be a virtual address.  So I corrected the
comment to indicate that this was a virtual address.

The only flash driver that was actually treating the address
as physical was the mtd/cfi_flash driver.  However, this code
was using it inconsistently as it actually directly dereferenced
the "start" element, while it used map_physmem to get a
virtual address in other places.  I changed this driver so
that the code which initializes the info->start field calls
map_physmem to get a virtual address, eliminating the need for
further map_physmem calls.  The code is now consistent.

The *only* place a physical address should be used is when defining the
flash banks list that is used to initialize the flash_info struct,
usually found in the board config file.
