I am doing the same,
what is the difference between these command sequence to generate u-boot using 1.1.2 and 1.1.3 without doing any further setting?
# make at91rm9200dk_config
# make
Should be the exactly the same

A quick watch to lowlevel_init.S shows that something low level is done here too ;-)
However CONFIG_SKIP_LOWLEVEL_INIT and/or CONFIG_SKIP_RELOCATE_UBOOT are not set as default for at91-dk,
so why version 1.1.3 (and only this version) doesn't run in ram?
P.S. Manual read ;-)
