I am really sorry, wanted to try this out when RMK returns from vacation
meanwhile forgot :(
The below logic from Rabin works great !!! no issues with this as well.
File arch/arm/mm/init.c
int pfn_valid(unsigned long pfn)
{
struct meminfo *mi = &meminfo;
unsigned int left = 0, right = mi->nr_banks;
while (left < right) {
unsigned int mid = (left + right) / 2;
struct membank *bank = &mi->bank[mid];
if (pfn < bank_pfn_start(bank))
right = mid;
else if (pfn >= bank_pfn_end(bank))
left = mid + 1;
else
return 1;
}
return 0;
}
Thanks for all the help.
Regards,
Khasim
