[PATCH 0/9] barebox KASan support

[Sascha Hauer]

This series adds KASan support to barebox. We already have ASan support
for sandbox which uses libasan, this time we get KASan for use on real
hardware. The KASan support is based on the Kernel code and contains the
subset of features we need for barebox. KASan is currently supported on
ARM(32/64) only and requires a supported allocator. Currently only the
TLSF allocator is supported.
