[v3] RISC-V: ACPI: Namespace updates

[PATCH v3 2/9] hw/riscv/virt-acpi-build.c: Update the HID of RISC-V UART

Posted by Sunil V L 4 months, 1 week ago

The requirement ACPI_060 in the RISC-V BRS specification [1], requires
NS16550 compatible UART to have the HID RSCV0003. So, update the HID for
the UART.
