[PATCH 0/3] ArmPlatformPkg: Fix Scripts/Ds5 debugging and Makefile

[Rebecca Cran]

I ran into some problems debugging EDK2 code using Development Studio with
the files under ArmPlatformPkg/Scripts and these patches fix them.

I'm using Arm Development Studio 2021.2 and not DS-5, so I'm not sure if
these changes would break things for people using the older environment.

[PATCH 1/3] ArmPlatformPkg: Fix error message in Scripts/Ds5/edk2_debugger.py

[Rebecca Cran]

An error message in Scripts/Ds5/edk2_debugger.py was missing the word
'not'.

[PATCH 2/3] ArmPlatformPkg: Fix target initialisation in cmd_load_symbols.py

[Rebecca Cran]

The debugger in Arm Development Studio 2021.2 doesn't work with
"ec = debugger.getExecutionContext(0)" because it's subsequently unable
to access memory. Fix it by switching to
"ec = debugger.getCurrentExecutionContext()".

The documentation for waitForStop() says:

"It is not needed after a call to stop() because stop() is blocking."

So, remove the call to waitForStop.

[PATCH 3/3] ArmPlatformPkg: Fix EDK2_DSC check in Scripts/Makefile

[Rebecca Cran]

With GNU Make 4.2.1, ifeq ($(EDK2_DSC),"") doesn't catch the case where
EDK2_DSC isn't defined. So, switch to using ifndef.

Also, I noticed Scripts/Makefile defaults to RVCT. Are people still using that, or has everyone moved to gcc or the newer Arm compilers?

Re: [PATCH 2/3] ArmPlatformPkg: Fix target initialisation in cmd_load_symbols.py

[Rebecca Cran]

Since the documentation was a bit difficult to find, I'll make a note here.

For Development Studio 2021.2 it was in 
/opt/arm/developmentstudio-2021.2/sw/ide/plugins/com.arm.debug.interpreter.jython.api_2021.2.0.20211118_074138/doc/arm_ds.html 
.

RVCT is 32-bit only, as far as I know, so I don't think anyone still
cares about it.

Thanks. If there's agreement I can put together a set of patches to 
remove support from the various places we have it in the tree (e.g. 
here, Conf/tools_def.txt etc.)
