* Support for sam9 "EMAC" controller.
* Support for rmii interface to phy.
at91.c & at91sam9.c:
* Eliminate separate at91sam9.c file.
* Add new devices to at91sam9_devs table.
at91_machdep.c & at at91sam9_machdep.c:
* Automatic chip type determination.
* Remove compile time chip dependencies.
* Eliminate separate at91sam9_machdep.c file.
at91_pmc.c:
* Corrected support for all of the sam926? and sam9g20 chips.
* Remove compile time chip dependencies.
My apologies to Greg for taking so long to take care of it.
rather than a fixed 512... This fixes the mount root problem on at91.
Prior to the SD card reorg, all data transfers were 512 bytes, so we
didn't notice.
o Only set 4-bit caps on those boards that have 4-bit caps (this means that
because we don't set wire4 yet, this forces us to always use 1-bit bus).
o Don't test wire4 when setting up the bus width, since bad things will
happen if we do.
# This likely won't fix the busted at91 sd card support, but these are
# needful changes for correctness.
sdhci supports up to 65535 blocks transfers, at91_mci - one block.
Enable multiblock operations disabled before to follow at91_mci driver
limitations.

This interface also appears in the AT91SAM9260 and '61 as well as the
AVR32 based micros from Atmel. We don't yet support write protect or
hot-swap in this bridge driver.
