Re: [U-Boot] [U-Boot-Users] [PATCH] ads5121: support for running from memory
Could you rebase it against current HEAD?
Sure. Here it is.
From ba2fc48842d6f866e30f52f457a4c834431e1167 Mon Sep 17 00:00:00 2001 From: Nikita V. Youshchenko yoush@debian.org Date: Tue, 2 Sep 2008 07:51:05 +0400 Subject: [PATCH] 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

You missed some changes in the rebase.
All CFG_ macros have been renamed to CONFIG_SYS_
