It seems that the flash memory is mapped to block devices by the kernel:

root at tirpitz:~> dmesg|grep -i flash
[    1.592000] physmap-flash physmap-flash.0: physmap platform flash device: [mem 0x00000000-0x03ffffff]
[    1.604000] physmap-flash.0: Found 2 x16 devices at 0x0 in 32-bit bank. Manufacturer ID 0x000001 Chip ID 0x002201
[    1.632000] Creating 4 MTD partitions on "physmap-flash.0":
root at tirpitz:~> ls -l /dev/mtdblock*
brw-rw---- 1 root disk 31, 0 Sep 30 12:35 /dev/mtdblock0
brw-rw---- 1 root disk 31, 1 Sep 30 12:35 /dev/mtdblock1
brw-rw---- 1 root disk 31, 2 Sep 30 12:35 /dev/mtdblock2
brw-rw---- 1 root disk 31, 3 Sep 30 12:35 /dev/mtdblock3
root at tirpitz:~>

So, I assume, I should just be able to write u-boot.bin to /dev/mtdblock0?
