net: marvell: prestera: Add PCI interface support
Add PCI interface driver for Prestera Switch ASICs family devices, which
provides:
- Firmware loading mechanism
- Requests & events handling to/from the firmware
- Access to the firmware on the bus level
The firmware has to be loaded each time the device is reset. The driver
is loading it from:
/lib/firmware/mrvl/prestera/mvsw_prestera_fw-v{MAJOR}.{MINOR}.img
The full firmware image version is located within the internal header
and consists of 3 numbers - MAJOR.MINOR.PATCH. Additionally, driver has
hard-coded minimum supported firmware version which it can work with:
MAJOR - reflects the support on ABI level between driver and loaded
firmware, this number should be the same for driver and loaded
firmware.
MINOR - this is the minimum supported version between driver and the
firmware.
PATCH - indicates only fixes, firmware ABI is not changed.
Firmware image file name contains only MAJOR and MINOR numbers to make
driver be compatible with any PATCH version.
