Hello,
this change adds more string functions: memchr, memcmp, memcpy, strcmp and strstr. It implements most of the printk formatting details. It then adds sprintf functions family and the stdio.h header. It then adds a simple serial port driver and registers it as a console when 'console=ttyS0' is seen in the command line.
I've lightly tested it, there still may be issues.
Please review/pull.
