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.
