[U-Boot] [PATCH v2 02/11] S3C24XX: Add core support for Samsung's S3C24XX SoCs
José Miguel Gonçalves

Fri Sep 14 19:28:53 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.
Signed-off-by: José Miguel Gonçalves <jose.goncalves at inov.pt>
---
Changes for v2:
- Added register bit macros to avoid magic numbers
- Removed volatile attribute from register structs
- Added s3c24x0_cpu.h to be able to use drivers from s3c24x0 family
- Fixed EPLL computation in get_PLLCLK for S3C2416
- Added display of UCLK in print_cpu_info
- Use of clrsetbits_le32()
