Hmm, what is this "0xC100" ?
/* turn off L2 cache */

What's about the order of #ifndef CONFIG_L2_OFF?
While we had before
#ifndef CONFIG_L2_OFF /* turn off L2 cache */ l2_cache_disable(); /* invalidate L2 cache also */ v7_flush_dcache_all(get_device_type()); #endif i = 0; /* mem barrier to sync up things */ asm("mcr p15, 0, %0, c7, c10, 4": :"r"(i));
#ifndef CONFIG_L2_OFF l2_cache_enable(); #endif
after this patch we would have
#ifndef CONFIG_L2_OFF if (get_device_type() != 0xC100) { /* turn off L2 cache */ l2_cache_disable(); /* invalidate L2 cache also */ v7_flush_dcache_all(get_device_type()); i = 0; /* mem barrier to sync up things */ asm("mcr p15, 0, %0, c7, c10, 4": :"r"(i));
l2_cache_enable(); } #endif
Is this intended?
Best regards
