Re: [openrisc] question about ORP

["Damjan Lampret" <lampret@opencores.org>]

Heya !

uclinux ran on xess xsv800 board and also on a proprietary board. These two
boards had different amount of RAM, xess xsv800 has 2MB. So you can compile
uclinux for 2MB or 8MB. Same with ethernet mac base address. ORP defines
that it should be at 0x92000000, where some other non-ORP system might put
it somewhere else. The thing is we just recently moved to ORP
memory/interrupts map so things might still be out of sync between software
(such as uclinux) and certain ORP hardware (such as orp_soc and xess).

In next few days there will be more updates on the web/cvs regarding ORP,
uclinux, orp_soc etc as things get synced.

regards,
Damjan
