GIT d14b272bc63f35a8f20b4b1df16c080b8d24f8f1 git+ssh://master.kernel.org/home/rmk/linux-2.6-arm.git#devel commit Author: Richard Purdie Date: Wed Sep 20 22:54:21 2006 +0100 [ARM] 3848/1: pxafb: Add option of fixing video modes and spitz QVGA mode support Add the ability to have pxafb use only certain fixed video modes (selected on a per platform basis). This is useful on production hardware such as the Zaurus cxx00 models where the valid modes are known in advance and any other modes could result in hardware damage. Following this, add support for the cxx00 QVGA mode. Mode information is passed to the lcd_power call to allowing the panel drivers to configure the display hardware accordingly (corgi_lcd already contains the functionality for the cxx00 panel). This mirrors the setup already used by w100fb.

When setting up the initial page tables (which is where this 4M limit is hardcoded), it's actually relatively easy to find out the true size of the uncompressed kernel image and create enough page table entries for things to fit, so this patch makes it so. In the decompressor, we also need to know the size of the uncompressed kernel image, to figure out whether there is any chance that uncompressing the kernel might overwrite the compressed kernel image stored elsewhere in memory. We don't have that info at this boot stage, though, so we approximate the size of the uncompressed kernel by taking the compressed kernel image size and allowing for a maximum 4x expansion.
