Thanks (I did a quick diff of other nand drivers, but missed the #error...).

I've put the kernel with latest mtd on my board and got the following:

Nand is recognized as 'NAND device: Manufacturer ID: 0x98, Chip ID: 0x75 
(Toshiba NAND 32MiB 3,3V 8-bit)',
should be 'NAND device: Manufacturer ID: 0xec, Chip ID: 0x75 (Samsung 
NAND 32MiB 3,3V 8-bit)'.

No bad blocks are detected at initial nand scan, but when running 
flash_eraseall all blocks are found bad.
