From 89f1fa080b5dca259c9779bcf81b95a409fdbf5b Mon Sep 17 00:00:00 2001 From: Ben Dooks Date: Fri, 29 Jan 2010 09:02:17 +0000 Subject: ARM: SAMSUNG: Move plat-s3c Kconfig entries to plat-samsung and plat-s3c24xx Move the Kconfig entries from plat-s3c to plat-samsung and plat-s3c24xx as necessary. The S3C_BOOT entries and the DMA configuration can go to plat-samsung. The low-level UART configurations are currently S3C2XX specific and can go to plat-s3c24xx. Eliminating plat-s3c from the build process will be submitted seperately.
