New board, EHL CRB, does not have legacy port IO UART. Even the PCI UART are not work due to BIOS's bug workaround(the BARs on LPSS PCI are reset after BIOS hand over control to OS). For ACRN console usage, expose the debug UART via ACPI PnP device (access by MMIO) and add support in hypervisor debug code. Another special thing is that register width of UART of EHL CRB is 1byte. Introduce reg_width for each struct console_uart. Tracked-On: #4937 Signed-off-by: Yin Fengwei <fengwei.yin@intel.com> Signed-off-by: Shuo A Liu <shuo.a.liu@intel.com> |
