From: Wolfgang Grandegger Date: Fri, 6 Jun 2008 11:50:05 +0000 (+0200) Subject: powerpc/85xx: support for the TQM8548 module using the big Flash X-Git-Tag: v2.6.27-rc1~1058^2~155 X-Git-Url: https://git.openpandora.org/cgi-bin/gitweb.cgi?p=pandora-kernel.git;a=commitdiff_plain;h=02b8a3d1eb2ae6353cfbce627ded22e299cf1989 powerpc/85xx: support for the TQM8548 module using the big Flash Some TQM85xx boards could be equipped with up to 1 GiB (NOR) flash memory and therefore a modified memory map is required and setup by the board loader. This patch adds an appropriate DTS file.
