* | msm: mdss: Reserve framebuffer memory for the splash screenSiddhartha Agrawal2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | Reserve memory for the framebuffer in the HLOS partition that would be used to display splash screen in the bootloader as well as the initial stages of the kernel bootup. This avoids copying splash screen memory to a local buffer in the kernel. The reserved memory would be freed when the first real update comes in from the userspace.

* | mdss: ppp: Allow for mdp3 to map smmu for buffers used by pppTerence Hampson2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | There is a hw issue with ppp where it reads buffers in 16x16 tiles. If the region of interest (roi) is not divisible by 16 it will read these extra lines but not use them for blitting. Since these extra region is outside the buffer it is necessary to add extra padding on either side of the buffer. This is a sw workaround to avoid smmu reporting page faults.

* | msm: mdss: change MDP burst length to 16 on 8x10Xiaoming Zhou2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Display DMA bus master is a real time client, which means it has strict timing requirement to meet the panel timing. If the data cannot be fetched from memory and sent to the panel fast enough within the panel timing constraint, the MDP DMA engine will be starving and cause under-run. Earlier, we were using burst length 8, this burst length configuration will cause under-run on the 720p panel which has high bandwidth requirement compared to WVGA panel. The burst length is now increased to 16. Change-Id: I1de8e453fa5d99634b6c0ab38ed8568c91516001 Signed-off-by: Xiaoming Zhou <zhoux@codeaurora.org>
