28 * Noteworthy Issues
29 * -----------------
30 *
31 * This driver is complicated by the fact that this is a 16-bit chip
32 * and, on at least one platform (ceiva), we can only do 16-bit reads
33 * and writes to the framebuffer. We hide this from user space
34 * except in the case of mmap().
35 *
36 *
37 * To Do
38 * -----
39 *
40 * - Test 8-bit pseudocolor mode
41 * - Allow setting bpp, virtual resolution
42 * - Implement horizontal panning
43 * - (maybe) Implement hardware cursor
