Use an existing kernel config symbol to fix devices whose ramstart is not zero. See upstream patch message for more details. Signed-off-by: Ilya Lipnitskiy <ilya.lipnitskiy@gmail.com> Cc: Tobias Wolf <dev-NTEO@vplace.de> Cc: Daniel Golle <daniel@makrotopia.org>

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