lib/bootconfig: Add override operator support
Add the value override operator (":=") support to the bootconfig. This value override operator will be useful for the bootloaders which will only update the existing bootconfig according to the bootloader boot options. Without this override operator, the bootloader needs to parse the existing bootconfig and update it. However, with this assignment, it can just append the updated (partial) bootconfig text at the tail of existing one without parsing it. (Of course, it must update the size, checksum and magic, but that will be done easily) Link: https://lkml.kernel.org/r/159482882954.126704.16209517125614438640.stgit@devnote2 Signed-off-by: Masami Hiramatsu <mhiramat@kernel.org> Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org>
