[ARM] 4509/1: S3C: Create initial arch/arm/plat-s3c

Browse Source 
Create the initial arch/arm/plat-s3c directory and start
linking it into the arch/arm build heirarchy ready to
receive the generic parts of the S3C24XX support to be
used when adding S3C6400 devices.

will trigger a reset and the system should restart.

help
Say Y here if you want verbose debugging from the PM Suspend and

config S3C2410_PM_CHECK
bool "S3C2410 PM Suspend Memory CRC"
depends on PLAT_S3C && PM && CRC32
help
Enable the PM code's memory area checksum over sleep. This option
will generate CRCs of all blocks of memory, and store them before
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.

depends on PLAT_S3C && PM && S3C2410_PM_CHECK
default 64
help
Set the chunksize in Kilobytes of the CRC for checking memory
corruption over suspend and resume. A smaller value will mean that
the CRC data block will take more memory, but wil identify any
faults with better precision.

config S3C2410_LOWLEVEL_UART_PORT
int "S3C2410 UART to use for low-level messages"
depends on PLAT_S3C
default 0
help
Choice of which UART port to use for the low-level messages,
such as the `Uncompressing...` at start time. The value of
this configuration should be between zero and two. The port
must have been initialised by the boot-loader before use.
