Very little additional code overhead, and only works when the user sets an
env var ahead of time, so default to on makes sense.

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.

Adds required definitions for EHCI support in sequoia configuration file.
But still keeps the OHCI as default driver.
Signed-off-by: Chris Zhang <chris@seamicro.com>
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
2 milliseconds". Without termination, a port stays at reset state. This is
observed on ppc4xx(sequoia) boards.

The RX Control/Status register has bits that we want to preserve, so don't
just write out a single bit. Preserve the others bits in the process.
The original code posted to the u-boot list had this behavior, but looks

The caddy2 is a variant of the already supported vme8349. So we just

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.

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.
