having the CPU device that's a child of atmelarm that does stuff.
o Create a linker_set for the support fucntions for the SoCs.
o Rename soc_data to soc_info.
o Move the delay and reset function pointers to new soc_data struct
o Create elements for all known SoCs
o Add lookup of the SoC we found, and print a warning if it isn't one
we know about.
SoC variants. Fold the AT91SAM9XE chips into the AT91SAM9260
handling, where appropriate. The following SoCs/SoC families are recognized:
at91cap9, at91rm9200, at91sam9260, at91sam9261, at91sam9263,
at91sam9g10, at91sam9g20, at91sam9g45, at91sam9n12, at91sam9rl,
at91sam9x5
and the following variations are also recognized:
at91rm9200_bga, at91rm9200_pqfp, at91sam9xe, at91sam9g45, at91sam9m10,
at91sam9g46, at91sam9m11, at91sam9g15, at91sam9g25, at91sam9g35,
at91sam9x25, at91sam9x35
This is only the identification routine: no additional Atmel devices
are supported at this time.
# With these changes, I'm able to boot to the point of identification
# on a few different Atmel SoCs that we don't yet support using the
# KB920X config file -- someday tht will be an ATMEL config file...
console so initialized will work upon return from cninit. While this
is the very next line, other platforms setup all this stuff before
calling cninit. Also, initialize the SDRAM base register in the inner
block in at91_ramsize().
* 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.
