2017-04-05Documentation: dt: chosen properties for arm64 kdumpJames Morse
Add documentation for DT properties: linux,usable-memory-range linux,elfcorehdr used by arm64 kdump. Those are, respectively, a usable memory range allocated to crash dump kernel and the elfcorehdr's location within it.

2015-10-27powerpc/book3e-64/kexec: Enable SMP releaseScott Wood
The SMP release mechanism for FSL book3e is different from when booting with normal hardware. In theory we could simulate the normal spin table mechanism, but not at the addresses U-Boot put in the device tree -- so there'd need to be even more communication between the kernel and kexec to set that up. Instead, kexec-tools will set a boolean property linux,booted-from-kexec in the /chosen node. Signed-off-by: Scott Wood <scottwood@freescale.com> Cc: devicetree@vger.kernel.org
2014-12-03of: Add bindings for chosen node, stdout-pathLeif Lindholm
Add a global binding for the chosen node. Include a description of the stdout-path, and an explicit statement on its extra options in the context of a UART console. Opening description stolen from www.devicetree.org, and part of the remaining text provided by Mark Rutland.
