- This file contains status information for the port of U-Boot to the
- Galileo Evaluation Board.

- The support for the Galileo Evaluation board is fairly minimal now.
- It's sufficient to boot Linux, but doesn't provide too much more than
- what's required to do this.
- Both DUART channels are supported (to use the second one, you have to
- modify the board -- see the schematics for where to solder on the
- devices module). The ethernet ports are supported, and the MPSC is
- supported as a console driver. (keep in mind that the kernel has no
- support 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 stable
- to use for Linux development, consider sticking with the DUART console
- for now.
- Automatic memory sizing mostly works. We've had problems with some
- combinations of memory. Please send us email if you're having trouble
- with respect to the memory detection.
- Right now, only the 512k boot flash is supported. Support for the
- 16MB flash on the devices module is forthcoming. Right now the flash
- is 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 not
- using 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 baudrate
- is set to 38400, 8N1.
- Good luck, and make sure to send any bugreports to us (or the
- u-boot-users list).
