hello, I have some problems with an mpc5200b based board. It\'s nearly compatible to the lite5200b board. I connected an samsung k9k8g08u0a nand flash via the lpb bus. This works fine with an self written nand driver. Now I try to use the standard nand driver from linux and configure it via the dts file. But this doesn\'t work and I get the following output: fc000000.flash: Found 1 x16 devices at 0x0 in 16-bit bank Amd/Fujitsu Extended Query Table at 0x0040 Using buffer write method fc000000.flash: CFI does not contain boot bank location.

Is it principle posible to configure a nand flash via the dts file (in combination with mpc5200b)? I read in some forums that the nand flash must be activated in the u-boot before it can be configured via dts. This makes no sense for me, but maybe it\'s true? I hope you can help me with my problem and if i made some style errors for the post, I say sorry.
