The patch titled
pm3fb: copyarea and partial imageblit suppor
has been removed from the -mm tree. Its filename was
pm3fb-copyarea-and-partial-imageblit-suppor.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: pm3fb: copyarea and partial imageblit suppor
From: Krzysztof Helt <krzysztof.h1@xxxxx>
This patch adds accelerated copyarea and partially accelerated imageblit
functions. There is also fixed one register address in the pm3fb.h file.
