The log mechanism, even in immediate mode, adds somewhere between 1K-2K of footprint to applications that use it. We want to standardize the logging APIs for all logging within the kernel, but need to not let platforms with very constrained RAM/ROM in the dust. This patch introduces CONFIG_LOG_MINIMAL, which is a very thin wrapper to printk(). It supports the APIs expressed in logging/log.h. This will be the new default for test cases.
