- *
- * - will be stored in the "cache" partition
- * - bad blocks will be ignored, like boot.img and recovery.img
- * - the first block will be the image header (described below)
- * - the size is in BYTES, inclusive of the header
- * - offsets are in BYTES from the start of the update header
- * - two raw bitmaps will be included, the "busy" and "fail" bitmaps
- * - for dream, the bitmaps will be 320x480x16bpp RGB565
