## Add Kernel Address Sanitizer functionality to coreboot
The Kernel Address Sanitizer (KASAN) is a runtime dynamic memory error detector.
The idea is to check every memory access (variables) for its validity
during runtime and find bugs like stack overflow or out-of-bounds accesses.
Implementing this stub into coreboot like "Undefined behavior sanitizer support"
would help to ensure code quality and make the runtime code more robust.
### Requirements
* knowledge in the coreboot build system and the concept of stages
* the KASAN feature can be improved in a way so that the memory space needed
during runtime is not on a fixed address provided during compile time but
determined during runtime. For this to achieve a small patch to the GCC will
be helpful. Therefore minor GCC knowledge would be beneficial.
* Implementation can be initially done in QEMU and improved on different
mainboards and platforms
