[PATCH 1/3] aspeed/g5: Device Tree for ast2500, copied from openbmc/linux (include file), plus minimal device tree configuration for ast2500 eval board.

Wed Sep 28 03:43:32 AEST 2016


From: Maxim Sloyko <maxims at google.com>

Fixed the bug in board initialization, which caused
failures during boot with device tree.
The flags are used to modify malloc behaviour after relocation,
resetting the flag caused it to fail.
