Suggest to split the imr_del() into 2 functions:-
(1) by address + size
(2) by IMR index
At current implementation, it does not support (2) only because it fails at
imr_check_range().
Hi Boon Leong.
I'll have a think about that :)
Just on imr_del() though, it does support removal by way of index.
+static void __init intel_galileo_imr_init(void)
+{
+ unsigned long base = virt_to_phys(&_text);
+ unsigned long size = virt_to_phys(&_sinittext) - base - IMR_ALIGN;
+ int i, ret;
+
+ /* Tear down all existing unlocked IMRs */
+ for (i = 0; i <= QUARK_X1000_IMR_NUM; i++)
+ imr_del(i, 0, 0);
That's what the platform code has to do for every unlocked IMR, to make
sure there are no stale IMRs left that could conflict with the EFI
memory map !
