Commit 155fa9af95ac5be857a7327e7a968a296e60d4c8 changed the way
to define a GPIO line, which can be used to force CS high
across multiple transactions. In order to fix sf detection
change board code to make use of board_spi_cs_gpio(..).

There are another two board that might be affected:

$ grep --exclude=ot1200.h -r SF_DEFAULT_CS include/configs/ | grep IMX_GPIO_NR
include/configs/aristainetos.h:#define CONFIG_SF_DEFAULT_CS		(0|(IMX_GPIO_NR(3, 20)<<8))
include/configs/tqma6.h:#define CONFIG_SF_DEFAULT_CS	(0 | (IMX_GPIO_NR(3, 19) << 8))

So, I'm CC'ing board maintainers, please test/fix them too. Thanks!

Anatolij

thanks for adding me to cc !

I fix this issue here:

http://git.denx.de/?p=u-boot/u-boot-imx.git;a=commit;h=2f6bb0a9419ec8016524142cb54fef81038b346e

already applied in the u-boot.imx tree ...

bye,
Heiko
