* 0xffffd760: size 0x100-bytes: First 0x80-bytes is for retail, the remaining 0x80-bytes at 0xffffd7e0 is for devunit. This 0x80-byte block is copied to 0x07ffcd00 by a Boot9 function, however that code actually does the copy in two 0x40-bytes chunks.

* 0xffffd860(end-addr of the above area) size 0x400-bytes: This is the bootrom_dataptr passed to the aes-keyinit function for retail.
* 0xffffd860(end-addr of the above area) size 0x400-bytes: This is the bootrom_dataptr passed to the aes-keyinit function for retail. See the below Tools section for how this is processed.
* 0xffffdc60(end-addr of the above area) size 0x400-bytes: This is the bootrom_dataptr passed to the aes-keyinit function for devunit. This is very last chunk of data in the boot9 data-section key-area: end addr for this area is 0xffffe060.
* 0xffffdc60(end-addr of the above area) size 0x400-bytes: This is the devunit version of the above the 0x400-byte chunk. This is very last chunk of data in the boot9 data-section key-area: end addr for this area is 0xffffe060.
