Hi,

this is somewhat offtopic, but I know no better place to ask. I'm trying to make the cs8900 ethernet chip on the Cogent CSB226 work with u-boot and Linux. The chip is mapped to 0x08000000 / CS2 and it is connected in I/O mapped mode.

However, I do not see anything usefull in u-boot. This is how the port area looks after power on:

uboot> md.w 0x08000000 10 (1) (2) (3) 08000000: 0000 a1ff 0000 a1ff 0009 a1ff 0000 a1ff ................ 08000010: 0000 a1ff 3136 a1ff 00d6 a1ff 00d6 a1ff ....61..........

This almost looks like accessing a 16bit device with a 32bit CS, and so getting (the same) junk on the first 16bit for every read.
