fa45bd498a Blackfin: kill off useless initdram() usage
While the initdram() function makes sense on some arches, it doesn't for
Blackfin systems as it's always implemented the same way.

fd04a05b89 Blackfin: update tiny board settings (voltage/default env)
The tinyboards like to run at a little lower voltage than the default, and
they prefer to boot over the network.  For the latter, extend the common
code a little to make this easier.

Also fix the cm-bf527 env sector size while we're in here to reflect the
flash that is actually in use.

b416191a14 Fix EHCI port reset.
In USB ehci driver, the port reset is not terminated. EHCI spec says "A host
 controller must terminate the reset and stabilize the state of the port within

 observed on ppc4xx(sequoia) boards.

7693640acd mpc83xx: spd_sdram.c: Disable memory controller before initializing
The memory controller could already be enabled, when spd_sdram() is
called. This could be the case for example, when the SDRAM is initialized
by the JTAG debugger.

The "sync" after the register access via the accessor function is
still needed, because the macro uses the sync before the real write
is done. So until not all accesses are converted to using accessor
functions, this sync still needs to be made "manually" here.

2e95004deb mpc83xx: Add NAND boot support for MPC8315E-RDB boards
The core support for NAND booting is there already, so this patch
is pretty straightforward.

There is one trick though: top level Makefile expects nand_spl to
be in nand_spl/board/$(BOARDDIR), but we can fully reuse the code
from mpc8313erdb boards, and so to not duplicate the code we just
symlink nand_spl/board/freescale/mpc8315erdb to mpc8313erdb.
