[U-Boot-Users] [Pacth]Some fixes on RPXlite DW

[Sam Song]

Hi,

I got a nudge from some folk chatting with Wolfgang 
about RESET and did this patch. All for RPXlite_DW
board.

* Patch by Sam Song, 21 August 2004:
  - Add RESET support for RPXlite_DW board
  - Adjust CPU:BUS frequency rato 1:1 when core
frequency less than 50MHz

Best regards,

Sam
