Subject: [PATCH 0/2] ARM: dts: aspeed: Add ASRock Rack B650D4U support
Date: Tue, 12 May 2026 23:20:17 +0530 [thread overview]
Message-ID: <20260512175019.47548-1-prasanth.padarthi10@gmail.com> (raw)
This series adds initial device tree support for the ASRock Rack
B650D4U BMC, which is based on the ASPEED AST2600 SoC.
The B650D4U is a server motherboard for AMD Ryzen processors. Hardware
details were extracted via reverse engineering of vendor firmware.
Hardware features included:
- UART5 Console
- MAC0 (RGMII) for dedicated management LAN
- I2C7 for FRU EEPROM
- FMC/SPI 64MB Flash layout
Validation:
Logic has been verified against the AST2600 v1.5 datasheet. The DTS
successfully compiles and was tested using QEMU (ast2600-evb) to verify
serial console output and board identification.
QEMU Boot Log Snippet:
