[PATCH 0/7] drm/ast: Various changes for video memory

[Thomas Zimmermann]

Various changes to detecting and organizing video memory on Aspeed
hardware. Resolves code duplication and cruft.

Patches 1 to 3 do a number of cleanups to the code for detecting
the size of the video memory. Patches 4 to 7 provide helpers for
calculating framebuffer and cursor locations within the video
memory.

Tested on AST2600 hardware.

  drm/ast: Replace AST_VIDMEM_SIZE_ with Linux SZ_ constants
  drm/ast: Add VGACRAA register constants
  drm/ast: Add VGACR99 register constants
  drm/ast: cursor: Add helpers for computing location in video memory
  drm/ast: Add helper for computing framebuffer location in video memory
  drm/ast: Remove vram_fb_available from struct ast_device
  drm/ast: cursor: Drop page alignment
