Subject: [PATCH] imx21ads : avoid overlapping static i/o mappings
Date: Sun, 26 Aug 2012 23:35:38 +0200 [thread overview]
Message-ID: <1346016938-28175-1-git-send-email-jaccon.bastiaansen@gmail.com> (raw)
The static I/O mappings for the cs89x0 ethernet controller and the
secondary AHB port 1 (SAHB1) overlapped, causing a kernel crash
at startup. This is fixed by mapping the cs89x0 to 0xf6000000 (which
is free to use according to arch/arm/plat-mxc/include/mach/hardware.h).
