My kernel is the linux-fsl (linux-2.6.35.3) with some changes made for configure the GPIOs and UARTs in our board (in mx53_loco.c) The bootloader I'm using is U-Boot 2013.10-rc3 Really I don=92t know if the L2 cache is enabled or not. How I can check this?

And I=B4m not sure which u-boot you=B4re = using. It may be anything! But, the only thing that came to my mind is L2 cache enabled or not. Do you know if you have enabled L2 cache?
