Re: [U-Boot] [PATCH v2, RFC] armv7: fixloop: don't fixup if location is invalid on RAM

Need to check that location is valid on RAM before the fixup.

Why this change? The [PATCH RFC] armv7: fixloop: don't fixup if location is NULL should be what you need. You could mention what causes these NULL fixups, here is commit entry for powerpc:

powerpc: do not fixup NULL ptrs

The fixup routine must not fixup NULL pointers. Problem can be seen by char *testfun(void) __attribute__((weak)); char *(*myfun)(void) = testfun;

Then add printf("myfun:%p, &myfun:%p\n", myfun, &myfun); before relocation and after relocation. myfun should be NULL in both cases but it is not.
