The RTL837x firmware images are organized as follows:
The first 2 bytes of the image give the size of the prefetched data at the
start of the CPU power up. The default is 0x4000 (bytes: 0x00 0x40), which
means that the entire shared area of the code memory in all banks,
0x4000 bytes is read immediately into the code RAM.
Common code starts at
0x0002 in the image and has length 0x3ffd, the first bank starts at 0x4000
in the image, is mapped to 0x4000 and has length 0xc000. The second bank
starts at 0x10000, is mapped to 0x4000 and has length 0xc000. The third
