This patchset adds a second UART to the ARM virt board, which can be useful in some cases where you'd like a second comms channel but don't want have to deal with PCI to get it.
Patch 3 attempts to add it to the ACPI tables, but this is entirely untested and pure guesswork, since I don't really know anything about ACPI. That patch needs review from somebody who does know ACPI :-) thanks -- PMM Peter Maydell (3): hw/arm/virt: Add virt-2.12 machine type hw/arm/virt: Add another UART to the virt board hw/arm/virt-acpi-build: Add second UART to ACPI tables include/hw/arm/virt.h | 2 ++ include/hw/compat.h | 3 +++ hw/arm/virt-acpi-build.c | 5 +++++ hw/arm/virt.c | 38 +++++++++++++++++++++++++++++++++----- 4 files changed, 43 insertions(+), 5 deletions(-) -- 2.7.4
