[PATCH 0/6] Allow setting of linux,stdout-path before kexec

[Samuel Mendoza-Jonas]

This series allows setting the linux,stdout-path device-tree property
based on the active console or a saved default. The primary motivation
is to make the boot progress between Petitboot and a booted kernel more
consistent. For example, currently if a user selects a kernel to boot
while on tty1, the selected kernel will boot with hvc0 (often IPMI) as
the primary boot console. Setting linux,stdout-path causes the kernel to
set its primary console to match the one that was used to select it.

If a user manually selects a kernel to boot the current console will be
set. However the user can also select a default console to be used,
which will be set as the primary console when a kernel boots due to an
auto-boot timeout.

The actual updating of the linux,stdout-path property is handled by the
30-add-offb boot hook after setting up the frame buffer.
