imx6dl external asynchronous SRAM

Hi All,

I have one doubt  on imx6dl platform

do we have  EIM_LBA polarity configurable ?

Note:

as EIM_LBA pin is connected to external SRAM latch pin which is a active high signal, 

Ideally we should have put a NOT gate between EIM_LBA  and Latch Enable pin of ext SRAM , as this EIM_LBA is active low, make ADDR to get latch this pin will be ZERO, but our ext SRAM latch pin is active HIGH, which does not work at all, 

guys any input on work around on software without making hardware change.

Hi shashikant
