[U-Boot-Users] u-boot environment variable setting: "console=ttyCPM0"

Hi,

I was recommended to use u-boot environment variable setting: "console=ttyCPM0" for loading linux-2.6.8-rc2 uImage (by u-boot) on to PQ2 ADS (with MPC 8270 on it). Could anyone knowledgeable ellaborate on usage of it for above described configuration ? What version of u-boot supports this setting ? What baud rate value I should add to this setting, if I want to use Hyperterminal serial connection ( over USB) to the board ?

TIA, Alex
