[U-Boot] [PATCH 2/7] S3C24XX: Add core support for Samsung's S3C24XX SoCs

José Miguel Gonçalves jose.goncalves at inov.pt
Wed Sep 12 13:15:18 CEST 2012


This patch adds the support for Samsung's S3C24XX SoCs that have an ARM926EJS core.
Currently it supports S3C2412, S3C2413, S3C2416 and S3C2450.
Tested on an S3C2416 platform.
