8 .. just a little something to get people going; contributors welcome!
11 Chip families supported:
25 Architectures supported:
28 - PPC (Motorola Powerstack)
35 At the moment, there are two kernel command line arguments supported:
41 Full support for startup video modes (modedb) will be integrated soon.
45 * Fix memory detection for 512kB case
48 * Hint for AXP: Use -accel false -vyres -1 when changing resolution
53 * Preliminary Laguna support
54 * Overhaul color register routines.
55 * Associated with the above, console colors are now obtained from a LUT
56 called 'palette' instead of from the VGA registers. This code was
57 modelled after that in atyfb and matroxfb.
58 * Code cleanup, add comments.
59 * Overhaul SR07 handling.
65 * Correctly set default startup video mode.
66 * Do not override ram size setting. Define
67 CLGEN_USE_HARDCODED_RAM_SETTINGS if you _do_ want to override the RAM
69 * Compile fixes related to new 2.3.x IORESOURCE_IO[PORT] symbol changes.
70 * Use new 2.3.x resource allocation.
77 * Assertions no longer cause an oops on purpose.
83 * Add compatibility support. Now requires a 2.1.x, 2.2.x or 2.3.x kernel.
88 * Several enhancements, smaller memory footprint, a few bugfixes.
89 * Requires kernel 2.3.14-pre1 or later.
94 * Bundled with kernel 2.3.14-pre1 or later.
