[Minios-devel] [UNIKRAFT PATCH 0/8] Process linker script and library specific Makefile.rules

[Sharan Santhanam <sharan.santhanam@xxxxxxxxx>]

The patch series provides the following features:
1. Each Unikraft library can extend the Unikraft build system providing a
   library specific Makefile.rules. The library Makefile.rules provides
   build rules specific to a library.

2. Unikraft current build system allows us to add extra linker script from
   a library as well as add a default linker script for a specific platform.
   The patch series from 2-8 allows the library developer to add the linker
   script as a source file and the linker scripts are automatically added to
   the platform specific linker command.

3. To differentiate the platform specific library from the common library a 
   PLATLIBNAME_PLATS is introduced to generate library rule specific to a
   platform.

3. For each platform the default linker script is defined using the variable
   UK_PLAT_*_DEF. 

4. An additional print-lds rule to print the linker scripts processed during
   the build.

This patch is based on the patch "build: Include Makefile.rules after .config 
is loaded".


Sharan Santhanam (8):
  build: Support Makefile.rules for each library
  build: Introduce PLATS variable for platform lib
  build: Introduce default linker script variable
  build: Use UK_PLAT_*_DEF_LDS in linker flag
  build: Automatically preprocess *.ldS
  build: Print linker script files
  build: Use linker script source to add the LDFLAGS
  build: Add *.ld files as source to library
