   4 Subject: [PATCH] MIPS: ralink: rt288x: select MIPS_AUTO_PFN_OFFSET
   5
   6 RT288X systems may have a non-zero ramstart causing problems with memory
   7 reservations and boot hangs, as well as messages like:
   8   Wasting 1048576 bytes for tracking 32768 unused pages
   9
  10 Both are alleviated by selecting MIPS_AUTO_PFN_OFFSET for such
  11 platforms.
  12
  13 Tested on a Belkin F5D8235 v1 RT2880 device.
