Attached is a patch to enable the GPIO on the 523x so that all 3

but the GPIO configuration is missing.
The change in mcfserial.c:

Needs to have "#ifdef CONFIG_M523x" around it.
And one style issue. Comments in the kernel should not be
c89/c++ style, don't use "//". See linux-2.6.x/Documentation/CodingStyle.
