No, I didn't, and I found out that my device is not yet ported to use
"Device Tree Support"
for the moment I will quick add the CONFIG_SRAM and see what happen,
but on the long term I move my code (clone of mach-mx27ads.c)
to DTS which makes absolute sense when I see how nice that code works.
Thanks for the reply!
