ARM: S3C2410: move mach-s3c2410/* into mach-s3c24xx/
This patch moves S3C2410 stuff into mach-s3c24xx/ directory so that we can merge the s3c24 series' directories to the just one mach-s3c24xx/ directory. And this patch is including following. - re-ordered alphabetically by option text at Kconfig and Makefile - removed unused option, MACH_N35 - fixed duplcated option name, S3C2410_DMA to S3C24XX_DMA which is in plat-s3c24xx/ Cc: Ben Dooks <ben-linux@fluff.org> Cc: Russell King <rmk+kernel@arm.linux.org.uk> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
