This patch is an example how device private CMA area can be activated.
It creates one CMA region and assigns it to the first s5p-fimc device on
Samsung Goni S5PC110 board.

This patch adds support for CMA to dma-mapping subsystem for ARM
architecture. By default a global CMA area is used, but specific devices
are allowed to have their private memory areas if required (they can be
created with dma_declare_contiguous() function during board
initialization).

The Contiguous Memory Allocator is a set of helper functions for DMA
mapping framework that improves allocations of contiguous memory chunks.
CMA grabs memory on system boot, marks it with CMA_MIGRATE_TYPE and
gives back to the system. Kernel is allowed to allocate movable pages
within CMA's

Hello everyone,
This is yet another round of Contiguous Memory Allocator patches. Now I
focused mainly on the integration of CMA to DMA mapping subsystem on ARM
architecture. In this version I've tried to solve the issue of the

Hi,
Siano modules already had sms_dbg flag which is a module parameter which
sets the debug mode so module prints messages to dmesg for debugging.
The variable was static therefore apply only to the file which defines
