MPC837XEMDS boards can support PCI-E via "PCI-E riser card". The card provides two PCI-E (x2) ports. Though, only one port can be used in x2 mode. Two ports can function simultaneously in x1 mode. PCI-E x1/x2 modes can be switched via "pex_x2" environment variable. Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: Kim Phillips <kim.phillips@freescale.com>
