Somehow my first patch got messed up. Please ignore this.
I will check the problem and send the patches again.
Best Regards,

Subject: [edk2-devel] [PATCH v2 1/2] Platform/RaspberryPi: Dynamically build UARTs info in ACPI
Changes: 1. Add code to ConfigDxe driver and AcpiTables module to dynamically build either Mini UART or PL011 UART info in ACPI. This fixes the issue discussed in https://github.com/pftf/RPi4/issues/118. 2. Cleanup by moving duplicate Debug Port 2 table related defines and structures to a newly created header file (RpiDebugPort2Table.h).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.Cc: Samer El-Haj-Mahmoud <samer.el-haj-mahmoud at arm.com>Cc: Sami Mujawar <sami.mujawar at arm.com>Cc: Jeremy Linton <jeremy.linton at arm.com>Cc: Pete Batard <pete at akeo.ie>Cc: Ard Biesheuvel <ardb+tianocore at kernel.org>Signed-off-by: Sunny Wang <sunny.wang at arm.com>--- .../RaspberryPi/AcpiTables/AcpiTables.inf | 9 +- .../RaspberryPi/AcpiTables/Dbg2MiniUart.aslc | 82 ++++++++ .../AcpiTables/{Dbg2.aslc => Dbg2Pl011.aslc} | 187 ++++++++--------- .../RaspberryPi/AcpiTables/SpcrMiniUart.aslc | 92 +++++++++ .../AcpiTables/{Spcr.aslc => SpcrPl011.aslc} | 188 +++++++++--------- Platform/RaspberryPi/AcpiTables/Uart.asl | 10 +- .../RaspberryPi/Drivers/ConfigDxe/ConfigDxe.c | 107 +++++++++- .../IndustryStandard/RpiDebugPort2Table.h | 34 ++++ 8 files changed, 497 insertions(+), 212 deletions(-) create mode 100644 Platform/RaspberryPi/AcpiTables/Dbg2MiniUart.aslc rename Platform/RaspberryPi/AcpiTables/{Dbg2.aslc => Dbg2Pl011.aslc} (72%) create mode 100644 Platform/RaspberryPi/AcpiTables/SpcrMiniUart.aslc rename Platform/RaspberryPi/AcpiTables/{Spcr.aslc => SpcrPl011.aslc} (87%) create mode 100644 Platform/RaspberryPi/Include/IndustryStandard/RpiDebugPort2Table.hdiff --git a/Platform/RaspberryPi/AcpiTables/AcpiTables.inf b/Platform/RaspberryPi/AcpiTables/AcpiTables.infindex d3363a76a1..fc8e927138 100644--- a/Platform/RaspberryPi/AcpiTables/AcpiTables.inf+++ b/Platform/RaspberryPi/AcpiTables/AcpiTables.inf@@ -2,7 +2,7 @@ # # ACPI table data and ASL sources required to boot the platform. #-# Copyright (c) 2019, ARM Limited.
