Functions | |
void | v6_flush_kern_cache_all_L2 (void) |
These functions are for synchronizing processor cache with RAM.

len | ) |
{ \ void *s = (void*)start; \ void *e = s + len; \ dmac_map_area(s, len, DMA_TO_DEVICE); \ outer_clean_range(__pa(s), __pa(e)); \ }
Clean a range of addresses from the cache. That is, write updates back to (RAM, next layer).

len | Number of bytes to flush |

void v6_flush_kern_cache_all_L2 | ( | void | ) |
ARM-routine to flush all cache. Defined here, because it exists in no easy-access header file. ARM-11 with L210 cache only!
