[Skiboot] [PATCH v2 0/7] set the kernel command line from nvram

[Oliver O'Halloran]

This series allows the kernel command line of the payload kernel to be
set from nvram. To do this it adds (partial) support for the configuration
string format used by the nvram utility provided by powerpc-utils.

Example usage:

nvram -p ibm,skiboot --update-config="bootargs=console=tty0 console=hvc0"

Changes from v1:
	Added tests
	Reworked some of the parsing logic
