[U-Boot] [PATCH V3 1/1] MX5: rename mx51 to mx5

Jason Liu r64343 at freescale.com
Mon Oct 18 04:50:28 CEST 2010


Rename mx51 to mx5 in order to support more mx51
like-style SOCs such as MX53 and the followings.

Signed-off-by: Jason Liu <r64343 at freescale.com>

---
Changes for v2:

Address the comments from Stefano Babic:
- rebase
- remove CONFIG_CPU_TYPE
- remove copyright change
- change vision2 board config

Changes for v3:
Address the comments from Wolfgang Denk:
- Change CONFIG_HCLK_FREQ to CONFIG_SYS_MX5_HCLK
- Change CONFIG_CLK32 to  CONFIG_SYS_MX5_CLK32
- Add "mx5" resp. "MX5" to the new identifier names.
