This option is not used by any ppc4xx cpu AFAIK. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Sunday, March 09, 2008 7:12 AM To: Wolfgang Denk; [email protected] Subject: Re: [U-Boot-Users] NAND flash programming via BDI2000 for ppc440epx.

It would be a very elegant solution to have U-Boot run from RAM with an environment in RAM to tell it what and where to flash... You could set up the environment while loading the data and would have a flexible flashing tool. The only thing missing for this is a working CONFIG_MONITOR_IS_IN_RAM as far as I can see.
