This file contains status information for the port of U-Boot to theGalileo Evaluation Board.Author: Josh Huber <huber@mclx.com> Mission Critical Linux, Inc.The support for the Galileo Evaluation board is fairly minimal now.It's sufficient to boot Linux, but doesn't provide too much more thanwhat's required to do this.Both DUART channels are supported (to use the second one, you have tomodify the board -- see the schematics for where to solder on thedevices module). The ethernet ports are supported, and the MPSC issupported as a console driver. (keep in mind that the kernel has nosupport for this yet)There are still occaisonal lockups with the MPSC console driver due to(we think!) overrun problems. If you're looking for something stableto use for Linux development, consider sticking with the DUART consolefor now.Automatic memory sizing mostly works. We've had problems with somecombinations of memory. Please send us email if you're having troublewith respect to the memory detection.Right now, only the 512k boot flash is supported. Support for the16MB flash on the devices module is forthcoming. Right now the flashis stored at the 256k boundry in flash, wasting a whole sector (64k!)for environment data. This isn't really a big deal since we're notusing the 512k for anything else. (Just U-Boot and the environment)Finally, here is a sample output session:U-Boot 1.0.0-pre1 (Jun 6 2001 - 12:45:11)Initializing... CPU: MPC7400 (altivec enabled) v2.9 Board: EVB64260 DRAM: 256 MB FLASH: 512 kB In: serial Out: serial Err: serial=>The default configuration should be correct for the evaluation board,as it's shipped from Galileo. Keep in mind that the default baudrateis set to 38400, 8N1.Good luck, and make sure to send any bugreports to us (or theu-boot-users list).Josh
