DRM: Armada: Add Armada DRM driver This patch adds support for the pair of LCD controllers on the Marvell Armada 510 SoCs. This driver supports: - multiple contiguous scanout buffers for video and graphics - shm backed cacheable buffer objects for X pixmaps for Vivante GPU acceleration - dual lcd0 and lcd1 crt operation - video overlay on each LCD crt via DRM planes - page flipping of the main scanout buffers - DRM prime for buffer export/import This driver is trivial to extend to other Armada SoCs. Included in this commit is the core driver with no output support; output support is platform and encoder driver dependent.

DRM: Armada: Add support for ARGB 32x64 or 64x32 hardware cursors This patch adds ARGB hardware cursor support to the DRM driver for the Marvell Armada SoCs. ARGB cursors are supported at either 32x64 or 64x32 resolutions.
