Chuanhong Guo 49c563a829 ramips: mt7621: add support for memory detection ... mt7621 has the following memory map: 0x0-0x1c000000: lower 448m memory 0x1c000000-0x2000000: peripheral registers 0x20000000-0x2400000: higher 64m memory detect_memory_region in arch/mips/kernel/setup.c only add the first memory region and isn't suitable for 512m memory detection because it may accidentally read the memory area for peripheral registers. This commit adds memory detection capability for mt7621: 1. add the highmem area when 512m is detected. 2. guard memcmp from accessing peripheral registers: This only happens when some weird user decided to change kernel load address to 256m or higher address. Since this is a quite unusual case, we just skip 512m testing and return 256m as memory size.
