[PATCH v7 0/2] ARM: dts: aspeed: Add ASRock Rack B650D4U BMC support

Add support for the ASRock Rack B650D4U BMC, based on the ASPEED AST2600 SoC.

The series adds the board compatible string and describes the BMC memory, SPI NOR flash layout, UART console, GPIO line names, graphics reserved memory, I2C EEPROM, and MAC0 connected to an RTL8211F Ethernet PHY.

MAC0 obtains its MAC address from the EEPROM on I2C7 and uses RGMII-ID mode.

Changes in v7:

* Correct the GPIOP bank line names for the reset, power and NMI button/control signals according to the confirmed board mapping.
* Remove the obsolete GPIOF5 reset-button line name.
* Leave the binding patch unchanged.

The B650D4U DTB builds successfully using aspeed_g5_defconfig.
