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.
