Bf60x support 16K, 64K, 16M and 64M cplb pages, this patch add support for them. So that bf609-ezkit can use it's 128M memory.
Checkpatch issues, please fix.
OK
-#define CPLB_PAGE_SIZE (4 * 1024 * 1024) -#define CPLB_PAGE_MASK (~(CPLB_PAGE_SIZE - 1))
...
uint32_t cplb_page_size;uint32_t cplb_page_mask;...
cplb_page_size = (4 * 1024 * 1024);cplb_page_mask = (~(cplb_page_size - 1));...
mbase &= CPLB_PAGE_MASK;mend &= CPLB_PAGE_MASK;
mbase &= cplb_page_mask;mend &= cplb_page_mask;What exsactly is the reason for replacing a compile-time calculation with a run-time one?
I will check with Bob on this change.
