Description
On x86 EFI, we currently hard-code sSerialBasePort on x86 and use it directly.
To assist in supporting alternative serial ports, we should likely only choose sSerialBasePort / 0x3f8 when no other options are available on x86.
To accomplish this, x86 should likely follow the design used from non-x86 platforms.
- src/system/boot/platform/efi/serial.cpp uses gUART if not NULL
- src/system/boot/platform/efi/dtb.cpp assigns gUART based on the optional dtb
- src/system/boot/platform/efi/acpi.cpp should also assign gUART based on the configured ports?
- src/system/kernel/arch/generic/debug_uart_8250.cpp could be used for x86? (even fixed 0x3f8?)
