net: mvneta: driver for Marvell Armada 370/XP network unit ...
This patch contains a new network driver for the network unit of the
ARM Marvell Armada 370 and the Armada XP. Both SoCs use the PJ4B
processor, a Marvell-developed ARM core that implements the ARMv7
instruction set.
Compared to previous ARM Marvell SoCs (Kirkwood, Orion, Discovery),
the network unit in Armada 370 and Armada XP is highly different. This
is the reason why this new 'mvneta' driver is needed, while the older
ARM Marvell SoCs use the 'mv643xx_eth' driver.
Here is an overview of the most important hardware changes that
require a new, specific, driver for the network unit of Armada 370/XP:
- The new network unit has a completely different design and layout
for the RX and TX descriptors. They are now organized as a simple
array (each RX and TX queue has base address and size of this
array) rather than a linked list as in the old SoCs.
- The new network unit has a different RXQ and TXQ management: this
management is done using special read/write counter registers,
while in the Old SocS, it was done using the Ownership bit in RX
and TX descriptors.
- The new network unit has different interrupt registers
- The new network unit way of cleaning of interrupts is not done by
writing to the cause register, but by updating per-queue counters
- The new network unit has different GMAC registers (link, speed,
duplex configuration) and different WRR registers.
- The new network unit has lots of new units like PnC (Parser and
Classifier), PMT, BM (Memory Buffer Management), xPON, and more.
The driver proposed in the current patch only handles the basic
features. Additional hardware features will progressively be supported
as needed.
