Hi Stefan,

I am Balaji.  am using IMX6 base custom board. In my board am using S29GL01G 
NOR Flash to srore u-boot and kernel. I understand from the data sheet this 
NOR Flash is CFI based on. So i have added Configurations for CFI Flash driver.

Currently am loading the U-boot into DDR3 and able to excute U-boot test 
commands. When i put flinfo , am getting "missing or unknow flash type" and 
while loading the u-boot it is printing as " Unknown flash on BANK 1 - Size - 
0MB". So am not sure what am missing here or i have to add anything extra in 
teh config file. Please request you to check and provide your suggestion.

Balaji S
