Enhance the Atmel SoC chip identification routines to account for more
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...
