The size and the name of flash partition are consistent
across use the R-Car Gen2 series.
This patch makes the koelsch board consistent with the lager board.

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
|.@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?

FYI, I have a koelsch board, and the layout out the flash is like:
0x0 0x10000 0x50000
|-- loader.bin --|-- uboot.bin --|-- something else --|
0 64K 320K 16M
But, I have no idea whether this is a standard layout or not.
thanks
