Adds a register to the config space for the 460sx. Changes the vc0 detect to a pll detect. maps configuration space to test the link status. changes the setup to enable gen2 devices to operate at gen2 speeds. fixes mapping that was not correct for the 460sx. added bit definitions for the OMRxMSKL registers. Removed reserved bit that was set incorrectly in the OMR2MSKL register. tested on the 460sx eiger and custom board Signed-off-by: Ayman El-Khashab <ayman@elkhashab.com> Signed-off-by: Josh Boyer <jwboyer@gmail.com>
