GPMC interface of C6A816x for NOR driver

Hi,

Where can I find GPMC based NOR driver for Integra in ezsdk's psp release ?
I want to use GPMC interface to work with HPI slave interface of other device.

This interface will be very much similar to NOR like device. I'll highly appreciate if any one can can help me to locate the NOR driver within kernel.

Thanks,
Sweta

    Hi Sweta,

    GPMC is initialized by U-Boot and used in Linux for NOR access. Linux only does pin-mux initialization and GPIO setup.

    Also, there is no separate NOR driver. The Linux PHYSMAP driver will use CFI to access NOR via GPMC address space.

    For GPMC initialization in U-Boot, please refer file arch/arm/cpu/arm_cortexa8/ti81xx/lowlevel_init.S in U-Boot source directory (in the same package).

    Regards
