The new 'init_platform' function performs the platform-specific component-local low-level initialization. It allows for the differentiation between core and regular components as well as kernel-dependent peculiarities. This patch introduces a consistent notion of a 'Platform'. Within core, the 'Platform' contains the kernel-specific initialization. Outside core, the platform sets up the interplay with the parent component. In all cases, the platform is constructed while running on the initial stack. Issue #4784
This directory contains library-description files. Each _<libname>.mk_ file contains the instructions for building the library _<libname>_. The .mk files are never used directly but they are implicitely processed by the build system. Libraries implementing one interface may have specialized implementations for different CPU architectures. Such architecture-specific _<libname>.mk_ files are located in corresponding _spec/_ subdirectories. For example, the .mk files of ARM-specific library variants reside in the _spec/arm/_ subdirectory. The build system automatically finds the appropriate _<libname>.mk_ file by evaluating the 'SPECS' build-configuration variable. Whenever the 'SPECS' variable contains 'arm', the build system considers the _spec/arm/_ directory.
