This isn't needed any more.

This removes the last remaining instance of glamo-kms-fb touching Glamo's
registers directly.

This doesn't work with the current 'standard' DDX, so there's no point trying
to make it work.

This increases the amount of memory exposed via the framebuffer.
This should eventually allow an fbdev-based DDX or a KMS DDX to
run on the same kernel, albeit suboptimally.

Doesn't work yet...

This also alters some debug lines.

That wasn't the right way to go about this. And it didn't compile.
This reverts commit d8e4b9ff4dc8bf57e53fa174f977c8fb00ec4e90.

This makes the GEM "info" ioctl produce an object handle which can be used to refer
to the front buffer (i.e. screen pixmap) in Xorg or otherwise. This is unfortunately
necessary since this memory is allocated in the kernel by the framebuffer driver, and
is not available to DRM until we move to KMS.

Removed the isr and everything interrupt related. IRQ is not
needed for basic operation on the glamo cmdq. This code directly
updates the write pointer of the queue without any waits.

This is the first step towards the irq based update of the write
pointer. With this revision the previous wait, and direct update is
deactivated.

This adds more of the bare bones for KMS, to be fleshed out later.

This implements the GEM 'create' ioctl.

This adds handling of Glamo's ring buffer at the kernel level, to be accessed
via ioctl DRM_GLAMO_CMDBUF.
