You are running on a board which actually is no mx28-evk, so it's no wonder
it doesn't work. Please mention that next time, because that changes the
question from "What is broken with the mx28-evk" to "What is different on
your board". This is a very important detail to answer questions.
Anyway, you say your board only has 64MiB of RAM, so you must at least
change:
ENTRY_FUNCTION(start_barebox_freescale_mx28evk, r0, r1, r2) {
barebox_arm_entry(IMX_MEMORY_BASE, SZ_128M, NULL); }
to SZ_64M. Other differences might include the pinmux and the UART port
number which is used for console output.
