Subject: [Qemu-riscv] [PATCH v3 22/28] riscv: sifive_u: Generate an aliases node in the device tree
Date: Sun, 11 Aug 2019 01:06:55 -0700

The Linux kernel SiFive UART driver expects an aliases node to be
present in the device tree, from which the driver extracts the port
number from "serial#" in the aliases node.
