[U-Boot-Users] immediate error when jumping to in_ram
Hi all:
We're adding a new board support to u-boot-0.2.0. At start, some relevant informaton has been printed out. But as soon as we jump to in_ram to execute the second half of init, an error/exception ocurred. By looking at ICR, it seems to be a ITLB error. But we don't know what shall be done with it. Thanks in advance.

Well, I haven't initialize the SDRAM properly. Sorry for disturbance.

Fix your RAM initialization. It is broken.
