Hi,
In the u-boot for omap3evm I use, cleanup_before_linux(in cpu/omap3/cpu.c or cpu/arm_cortexa8/cpu.c) turns off L2 cache by mistake, it should not. This causes serious performance problem for me.
The following line "#ifndef CONFIG_L2_OFF" should be "#ifdef CONFIG_L2_OFF".
#ifndef CONFIG_L2_OFF
/* turn off L2 cache */
l2cache_disable();
/* invalidate L2 cache also */
v7_flush_dcache_all(get_device_type());
#endif
Regards
Wending
