This version fixes pointed issues. Is it better? commit 03f4cf26950e498d83c21fd040977db9633d77e2 Author: Nikita V. Youshchenko <[EMAIL PROTECTED]> Date: Tue Sep 2 07:51:05 2008 +0400
ads5121: support for running from RAM
This patch makes it possible to start u-boot from RAM on ads5121 board.
It does two simple things:
- skips initialization of RAM controller if already running from RAM,
- makes CONFIG_ENV_ADDR absolute, not relative to CFG_MONITOR_BASE
