Subject: Add bootsplash image scaler
Patch-mainline: Never
References: bnc#570082
The initrd most often contains a single fixed size boot image which is of the
size of the VESA framebuffer used for boot. If the size of the framebuffer
changes when KMS is initialized for example the boot splash is turned off.
Takashi Iwai has provided a patch which allows to add multiple images to initrd
so that the kernel can select the appropriate size. This is only feasible for
mobile devices with a build in panel of a fixed resolution in which case one
would have to ship two images at the most: the one of the VESA resolution at
boot time and the one of the panel as used by KMS.
The attached patch adds a boot splash scaler which allows the down scaling of
bootsplash image which is bigger than the screen size. This way by supplying a
single image large enough to accomodate the largest screens possible all
resolutions can be derived from it.
