[U-Boot] Can't boot DaVinci EVM with Green Hills' Integrity OS

[Idan Noti]

Why do you think caches have something to do with the problem?

Also, how do I config the compilation to disable caches? The only
configuration I'm aware about it modifying the header file:
$(uboot_folder)/include/configs/davinci_dvevm.h

Thanks
