This is something that has been on the Raspberry Pi platform TODO list for some time, so your contribution is much appreciated.

Ideally, I would prefer if 1-3 and 2 were submitted as separate patches in a series, as one can consider that the ACPI assigning of the Spcr/Dbg2 tables is independent of the Bluetooth related changes. For instance, regardless of Bluetooth usage, one of course wants the serial ports used by Windows to match the ones defined in config.txt. So I would say that we have at least two separate functional changes in this patch, that should probably be made more explicit by splitting them into separare commits. > Testing Done: > > - Booted to UEFI shell and use acpiview command to check the result of > > the different UART settings in config.txt (enabling either Mini UART > > or PL011) and SPCR, DBG2 tables and device BTH0 are dynamically > > changed as expected. > > - Successfully booted Windows 10 (20279.1) on SD (made by WOR) with > > the RPi-Windows-Drivers release ver 0.5 downloaded from > > https://github.com/worproject/RPi-Windows-Drivers/releases > > and checked that both Bluetooth and serial port (Mini UART) can > > work fine. > > > > Cc: Samer El-Haj-Mahmoud > > Cc: Pete Batard > > Cc: Ard Biesheuvel > > Cc: Leif Lindholm > > Signed-off-by: Sunny Hsuan-Wen Wang > > --- > > .../RaspberryPi/AcpiTables/AcpiTables.inf | 7 +- > > .../RaspberryPi/AcpiTables/Dbg2MiniUart.aslc | 82 ++++++++ > > .../AcpiTables/{Dbg2.aslc => Dbg2Pl011.aslc} | 187 ++++++++--------- > > .../RaspberryPi/AcpiTables/SpcrMiniUart.aslc | 92 +++++++++ > > .../AcpiTables/{Spcr.aslc => SpcrPl011.aslc} | 189 +++++++++--------- > > Platform/RaspberryPi/AcpiTables/Uart.asl | 18 +- > > .../RaspberryPi/Drivers/ConfigDxe/ConfigDxe.c | 123 +++++++++++- > > .../IndustryStandard/RpiDebugPort2Table.h | 33 +++ > > 8 files changed, 516 insertions(+), 215 deletions(-) > > create mode 100644 Platform/RaspberryPi/AcpiTables/Dbg2MiniUart.aslc > > rename Platform/RaspberryPi/AcpiTables/{Dbg2.aslc => Dbg2Pl011.aslc} (73%) > > create mode 100644 Platform/RaspberryPi/AcpiTables/SpcrMiniUart.aslc > > rename Platform/RaspberryPi/AcpiTables/{Spcr.aslc => SpcrPl011.aslc} (88%) > > create mode 100644 Platform/RaspberryPi/Include/IndustryStandard/RpiDebugPort2Table.h > > > > diff --git a/Platform/RaspberryPi/AcpiTables/AcpiTables.inf b/Platform/RaspberryPi/AcpiTables/AcpiTables.inf > > index d2cce074e5..6c08cacbb3 100644 > > --- a/Platform/RaspberryPi/AcpiTables/AcpiTables.inf > > +++ b/Platform/RaspberryPi/AcpiTables/AcpiTables.inf > > @@ -2,6 +2,7 @@ > > # > > # ACPI table data and ASL sources required to boot the platform. > > # > > +# Copyright (c) 2021, Sunny Hsuan-Wen Wang > > # Copyright (c) 2019, ARM Limited.
