[PATCH 0/6] simple framebuffer driver with RPi support

[Andre Heider]

This set adds a common simple framebuffer driver for platforms which choose
to support it. RPi support is part of this set.

The driver serves two functions:
* a framebuffer driver for barebox
* pass an active framebuffer configuration to a loaded kernel

For the latter to work the loaded kernel has to be CONFIG_FB_SIMPLE enabled.

Depending on the configured video mode, the RPi video hardware sets up a
framebuffer with noncontiguous horizonal lines. Patch 1, 2 and 3 prepare
common fb and gui code to support that.

Patch 4 is the driver itself, patch 6 adds support for simplefb to RPi.

Patch 5 just adds a missing field on a fb related mbox response.

Thanks,
Andre
