I'am trying to connect simple device (eg latched LED port) to the 8-bit EIM port on the mx53 board under Linux (adapted 3.2.28). By no chance this is working inside Linux kernel although works nice in the u-boot.
I've checked emi_slow_clock, even try to change the logic for ioremap (which is by the way erroneus) without success.
I've tried with 64M_64M coniguration and 32M_32M_32M_32M also without success.
I could not read neither write to that region.
Any hint/advice would be much appreciated.
