Hi,

Just an update on the discussion that we had yesterday in the Cougar
meeting.  Broadcom has the SiByte 1125H processor that provides the
following:

- 1 CPU core
- 32-bit PCI bus
- 2 * GE interfaces
- DDR memory controller
- 2 UARTs

I am going to look at using the 1125 as a standalone processor, and as
we discussed yesterday, this will largely be a function of board space
and cost.  If we move forward with the 1125, then I would propose
eliminating the BCM5715 dual MAC and using the native GE interfaces of
the 1125.  I would also look at using soldered-down DDR1 SDRAM that is
fixed at 512MB if that helps with the layout.


Brian
