[PATCH v2 2/2] ACPI: SPCR: Workaround for APM X-Gene 8250 UART 32-alignment errata

2017-07-03 Thread Loc Ho
APM X-Gene verion 1 and 2 have an 8250 UART with its register aligned to 32-bit. In addition, the latest released BIOS encodes the access field as 8-bit access instead 32-bit access. This causes no console with ACPI boot as the console will not match X-Gene UART port due to the lack of mmio32 optio
