e78f36e229 SAMA5: Update from David Sidrane to last RAM function change: Apparently inline functions need to placed into the same RAM section, or they do not get inlined. From David Sidrane 2014-04-04 08:59:39 -06:00

38e49b48c5 SAMA5: On some hardware, reconfiguring the PLL while executing out of NOR FLASH causes crashes. This was fixed by David Sidrane by implementing RAM functions. The killer code is copied and executed from ISRAM and the crash is avoided. 2014-04-03 16:08:18 -06:00
