Damian Hobson-Garcia 06c8a6a3e4 fbdev: sh_mobile_meram: Correct pointer check for YCbCr chroma plane 
The check was intended to test if we have a valid pointer to write into,
but it mistakenly checks the pointer contents instead.

Since a valid pointer is mandatory for the chroma data if a YCbCr format
is used, the pointer check has been removed.

Damian 3fedd2ac76 sh_mobile_meram: Add support for NV24 framebuffers 
Since the NV24 framebuffer has a CbCr plane that is twice as wide
as the Y plane, it needs to be handled as a special case.

Damian 7caa4342ca sh_mobile_meram: MERAM framework for LCDC 
Based on the patch by Takanari Hayama <taki@igel.co.jp>

Adds support framework necessary to use Media RAM (MERAM)
caching functionality with the LCDC.  The MERAM is accessed
through up to 4 Interconnect Buffers (ICBs).

ICB numbers and MERAM address ranges to use are specified in
by filling in the .meram_cfg member of the LCDC platform data
