Does this match the actual data in the FLASH?

On my board, the SPI boot loader is at 0x00000000.
There's also a small unidentified chunk at 0x00040000:

    00040000  00 40 30 e6 5c 3a 03 00  ff ff ff ff ff ff ff ff
|. at 0.\:..........|

u-Boot seems to be at 0x00080000.
u-Boot environment variables are saved at 0x000c0000.
This does match the old "bootenv" partition.

After that it's all-zeroes until 0x00100000, where I did my SPI tests,
based on the old layout.

Do I have a non-standard Koelsch FLASH layout on my board?
