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.

Merge changes in edk2-platforms-raspberrypi-pl011-bth-noflow.diff in
https://github.com/worproject/RPi-Bluetooth-Testing/ for enabling
Bluetooth and serial port (Mini UART) in Windows OS.
Testing Done:
- 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.

Hi Sunny,
I understand that you are going to re-send these patches due to e-mail
mangling, but let me add a few of notes that might help you as you are
doing that.
First of all, your patch series was missing a cover letter (there should
have been a [PATCH v2 0/2]), that doesn't get applied, but that
describes the series or the changes applied between 2 revisions.
This isn't a big deal for a series that has only 2 patches, but it seems
to indicate that you missed some steps from Laszlo's helpful guide on
how to configure your environment to send patches to EDK2, which you can
find at:
https://github.com/tianocore/tianocore.github.io/wiki/Laszlo%27s-unkempt-git-guide-for-edk2-contributors-and-maintainers
Especially, you should have run the command:
git config format.coverletter true
Now, with regards to patch mangling, as you may be able to see, what I
got is not as bad as what you seem to have been getting. In fact,
barring a few issues (which I am pointing out below) your patch is
almost usable, even with the double line feeds I am seeing from my
e-mail client (because that's actually how I currently receive about
half the patches that are posted on this list anyway, so much so that I
have had to craft a quick script to remove them).
There are however some issues, that actually prevent your patch from
applying properly, and, while I'm at it, I also added a few comments
about some extra lines you added, that you should be able to fix for
your next submission:

Same here, and for about 4-5 more instances further down, that I'm not
going to document.
If using 'git format-patch' and 'git send-email' as documented in
Laszlo's guide, I would expect these to go away.

This doesn't have to do with patch mangling, but you are adding an
unwarranted extra line here. Can you please remove it from your next

So, IMHO its better to extend the existing table driven nameop
replacement scheme than create a compeltely custom function here. Part
of that is because we will want to potentially apply some further user
configuration to the DSDT (say customizing the _PSV value), and some of
it is my own bias to keep this generic.
I think there are at least two ways to pull this off, the first is to
use a new NameOp integer tied to mUse???Uart to select the correct
string (similarly to how the emmc is selecting a differing Package()) in
AML. The other choice is to extend the existing UpdateSsdtNameOps to
suport strings. I personally would pick the first choice since it seems
easier.

This else/return, return is odd since the second return should be
redundant yet has a differing return.

Same here:
So that said, it might be worth considering if the DBG2/SPCR OemId's are
diffrent that these table could be handled by the same logic handing
enabling/disabling the SSDT's since each table is enabled by a single
true/false value.

Is there a case where we don't want at least one of these set?

Having come to this a bit late, its always made me a bit uncomfortable
that some of these tables are doing blanket power/etc configuration in
_CRS, is there are reason for continuing this rather than doing this via
power states?

This line should be completely removed.
BT_ON is configured by the firmware, and the Windows driver doesn't touch it.

This always assumes that PL011 is used for Bluetooth. The pin muxing could be done in ConfigDxe depending on which UART is unused.
Also, pin 31 should be set as a LOW output pin rather than relying on the default configuration of BCM_ALT2.
