We are writing a driver to access the memory area of CS2  0x0800_0000.
I'm using the pxa_gpio_mode(GPIO78_nCS_2) to set the gpio mode for CS2 and
for base address PXA_CS2_PHYS.
When I run the a test user program I don't see any activity on the pin with the osciloscop.
According to the intel timing diagram CS is high and should transition low when active.
 
I'm not sure if there is anything else I need to configure to enable this memory range.
