 6The original Linux support for this product has been provided by
 7Nicolas Pitre <nico@cam.org>. Continued development work by
 8Woojung Huh <whuh@applieddata.net>

10Use 'make graphicsmaster_config' before any 'make config'.
11This will set up defaults for GraphicsMaster support.
12
13The kernel zImage is linked to be loaded and executed at 0xc0400000.
14
15Linux can  be used with the ADS BootLoader that ships with the
16newer rev boards. See their documentation on how to load Linux.

37Notes:
38
39- The flash on board is divided into 3 partitions.  mtd0 is where
40  the zImage is stored.  It's been marked as read-only to keep you
41  from blasting over the bootloader. :)  mtd1 is
42  for the ramdisk.gz image.  mtd2 is user flash space and can be
43  utilized for either JFFS or if you're feeling crazy, running ext2
44  on top of it. If you're not using the ADS bootloader, you're
45  welcome to blast over the mtd1 partition also.
46
47- 16bpp mode requires a different cable than what ships with the board.
48  Contact ADS or look through the manual to wire your own. Currently,
49  if you compile with 16bit mode support and switch into a lower bpp
50  mode, the timing is off so the image is corrupted.  This will be
51  fixed soon.
