+Subject: [PATCH 3/3] net: phy: aquantia: add firmware load support
+
+Aquantia PHY-s require firmware to be loaded before they start operating.
+It can be automatically loaded in case when there is a SPI-NOR connected
+to Aquantia PHY-s or can be loaded from the host via MDIO.
+
+This patch adds support for loading the firmware via MDIO as in most cases
+there is no SPI-NOR being used to save on cost.
+Firmware loading code itself is ported from mainline U-boot with cleanups.
+
+The firmware has mixed values both in big and little endian.
+PHY core itself is big-endian but it expects values to be in little-endian.
+The firmware is little-endian but CRC-16 value for it is stored at the end
+of firmware in big-endian.
+
+It seems the PHY does the conversion internally from firmware that is
+little-endian to the PHY that is big-endian on using the mailbox
+but mailbox returns a big-endian CRC-16 to verify the written data
+integrity.
