This is what I got currently (mainline):

U-Boot 2014.01-rc1-00165-ge03c76c (Dec 12 2013 - 09:26:20)

I2C:   ready
DRAM:  128 MiB
Enable d-cache
DFU USB: VID = 0x 908, PID = 0x 2d2
NAND:  256 MiB
MMC:   OMAP SD/MMC: 0, OMAP SD/MMC: 1
Net:   cpsw

So caches seem to be enabled, right? Or is i-cache still missing?

Thanks,
Stefan
