296f5568c6 mfd: intel-m10-bmc: Expose MAC address and count
Create two sysfs entries for exposing the MAC address and count
from the MAX10 BMC register space. The MAC address is the first
in a sequential block of MAC addresses reserved for the FPGA card.
The MAC count is the number of MAC addresses in the reserved block.

876611c493 mfd: intel-m10-bmc: Add Intel MAX 10 BMC chip support for Intel FPGA PAC
This patch implements the basic functions of the BMC chip for some Intel
FPGA PCIe Acceleration Cards (PAC). The BMC is implemented using the
Intel MAX 10 CPLD.

This BMC chip is connected to the FPGA by a SPI bus. To provide direct
register access from the FPGA, the "SPI slave to Avalon Master Bridge"
(spi-avmm) IP is integrated in the chip. It converts encoded streams of
bytes from the host to the internal register read/write on the Avalon
bus. So This driver uses the regmap-spi-avmm for register accessing.
