- * Noteworthy Issues
- * -----------------
- *
- * This driver is complicated by the fact that this is a 16-bit chip
- * and, on at least one platform (ceiva), we can only do 16-bit reads
- * and writes to the framebuffer.  We hide this from user space
- * except in the case of mmap().
- *
- *
- * To Do
- * -----
- *
- * - Test 8-bit pseudocolor mode
- * - Allow setting bpp, virtual resolution
- * - Implement horizontal panning
- * - (maybe) Implement hardware cursor
