instead of reading the registers everytime
the current implementation respect the following constrain:
- allow 1 to n soc to be enabled
- allow to have a virtual cpu type and subtype
- always detect the cpu type and subtype and report it
- detect if the soc support is enabled
- prepare for sysfs export support
- drop soc specific code via compiler when the soc not enabled
(via cpu_is_xxx)
Today if we read the exid we will have the same value for 9g35 and 9m11
and we will need to check the cidr too
with the new implementation we just need to check the soc subtype
this will also allow to have specific virtual subtype for rm9200 which the
board will have to specify via at91rm9200_set_type(int) as we have no way to
detect it.
this implementation is inspired by the SH cpu detection support

On all at91 except rm9200 and x40 have the System Controller starts
at address 0xffffc000 and has a size of 16KiB.
On rm9200 it's start at 0xfffe4000 of 111KiB with non reserved data starting
at 0xfffff000
This patch removes the individual definitions of AT91_BASE_SYS and
replaces them with a common version at base 0xfffffc000 and size 16KiB
and map the same memory space

The recently modified nand buswitth configuration is not aligned with
board reality: the double footprint on boards is always populated with 8bits
buswidth nand flashes.
So we have to consider that without particular configuration the 8bits
buswidth is selected by default.
Moreover, the previous logic was always using !board_have_nand_8bit(), we
change it to a simpler: board_have_nand_16bit().

Hello,
I am not 100% sure this is the right thing to do, but it makes the
atmel-ssc driver happy on my at91rm9200 board.
This unifies the con_id across all at91 machines.
The atmel-ssc driver expects the con_id to be "pclk" or it will fail probing.

Needed to update to apply fixes for which the old branch was too
outdated.
The AT91 MCI has special SDIO transfer types: SDIO block and SDIO byte
transfers, but at91_mci driver doesn't use them and handles all SDIO
transfers as ordinary MMC block transfers. This causes problems for
multiple-block SDIO transfers (in particular for 256-bytes blocks).
Fix this situation by checking the opcode for SDIO CMD53 and setting
the transfer type in the AT91_MCI_CMDR register properly.
This patch was tested with libertas SDIO driver: problem with TX
timeouts on big packets was eliminated.
