Sascha,
in your last NAND driver rework, you removed the RESET command.
The reset commant is necessary in order to get Micron Nand running as
they need a RESET command before being able to get any command.
All my test done this weekend were fine as I did boot the board with the
previous uboot which once resetted the NAND ... but today after a
powercycle, I wasn't able to read the ID of the flash ...
Here is the patch which fix this behaviour.
Eric
nand_imx driver must support the RESET Command in order to support
Micron NAND.
