When we import code from Linux, with regular re-sync planned, we want to use printk() and pr_*(). U-Boot does not support them in a clean way. So, people end up with local macros, or compat headers here and there, then we occasionally see build errors of definition conflicts. We have include/linux/compat.h, but putting all sorts of unrelated things into a single header is just a temporal workaround. Hence this patch, to find the best home for all printk variants. If you want to use printk() and friends, please include <linux/printk.h>. This header is self-contained, and pulls in only a few headers. When I was testing this clean-up, I noticed the image size exceeded its platform limit on some boards. This is because all pr_*() that were previously defined as no-op in include/linux/mtd/mtd.h (unless CONFIG_MTD_DEBUG is set), are now enabled. To make such boards happy, this commit also implements CONFIG_LOGLEVEL. The concept is similar to the kernel parameter "loglevel". (Actually, the Kconfig help message was taken from kernel-paremeter.txt of Linux) Messages with a loglevel smaller than console loglevel will be printed. The difference is the loglevel is build-time determined. To save the image size, lower priority pr_*() are compiled out. I set the default of CONFIG_LOGLEVEL to 6, i.e. pr_notice and higher priority messages are compiled in. I adjusted CONFIG_LOGLEVEL to avoid build error for some boards.
