Re: [PATCH v2 0/2] Dynamic ACPI framework for fsl layerscape platforms

["Leif Lindholm" <leif@nuviainc.com>]

Hi Vikas,

Apologies for very slow review.

However, this set doesn't build for me.
It fails with

In file included from /work/git/edk2-platforms/Platform/NXP/ConfigurationManagerPkg/ConfigurationManagerDxe/ConfigurationManager.c:26:
/work/git/edk2-platforms/Platform/NXP/ConfigurationManagerPkg/ConfigurationManagerDxe/ConfigurationManager.h:17:10: fatal error: Platform.h: No such file or directory
 #include <Platform.h>
           ^~~~~~~~~~~~

Since the location of ConfigurationManagerPkg suggests the intent to
use this for additional platforms in the future, this cannot be
resolved by referencing LX2160aRdbPkg.dec from
ConfigurationManagerDxe.inf.

I would suggest doing like the ARM VExpressPkg and add:
[BuildOptions]
  GCC:*_*_AARCH64_PLATFORM_FLAGS == -I$(WORKSPACE)/Platform/NXP/LX2160aRdbPkg/Include
to LX2160aRdbPkg.dsc.

Also, I'm seeing a build failure in edk2 DynamicTablesPkg when
building with NOOPT:
/work/git/edk2/DynamicTablesPkg/Library/Common/AmlLib/NameSpace/AmlNameSpace.c: In function ‘AmlEnumeratePathCallback’:
/work/git/edk2/DynamicTablesPkg/Library/Common/AmlLib/NameSpace/AmlNameSpace.c:1081:31: error: variable ‘CurrNodePath’ set but not used [-Werror=unused-but-set-variable]
   CHAR8                     * CurrNodePath;
                               ^~~~~~~~~~~~
/work/git/edk2/DynamicTablesPkg/Library/Common/AmlLib/NameSpace/AmlNameSpace.c:1078:31: error: variable ‘SearchedPath’ set but not used [-Werror=unused-but-set-variable]
   CHAR8                     * SearchedPath;
                               ^~~~~~~~~~~~

Sami - can you have a look at that?

I'll follow up with a couple of minor comments on the patches.

Best Regards,

Leif
