| Summary | 0007264: Fix fsimx6 CMA allocation | ||||
| Description | The new kernel allocates CMA always at the end of the DRAM. This leads to problems if the CMA is bigger than the higher part of the DRAM and crosses the boarder between normal RAM and high RAM. For example: i.MX6 Normal RAM goes from 0x10000000 to 0x7FFFFFFF i.MX6 High RAM goes from 0x80000000 to 0xFFFFFFFF If a board has 2GB DRAM and the CMA size is 320MB the CMA will go from 0x7c000000..0x8ffffff. The CMA lies in Normal and High RAM and allocation will fail. To prevent this we set the maximum range of the CMA allocation to 0x6C000000. This has to be adapted if CMA_SIZE > 320MB | ||||
