Update the Kconfig to create configuration options based on which CPUs are supported for the low level serial code. This means that the debug macros can be optimised for the type(s) of CPU that are being used. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

Enable the PM code's memory area checksum over sleep. This option

going to sleep. The blocks are then checked on resume for any

errors.

Note, this can take several seconds depending on memory size

and CPU speed.

Set the chunksize in Kilobytes of the CRC for checking memory

the CRC data block will take more memory, but wil identify any

faults with better precision.
