2017-12-15dt-bindings: chosen: Document linux,initrd-{start,end}Jonathan Neuschäfer1-0/+15
These properties have been in use for a very long time (at least since 2005), but were never documented in chosen.txt. Signed-off-by: Jonathan Neuschäfer <j.neuschaefer@gmx.net> Signed-off-by: Rob Herring <robh@kernel.org>
2017-07-24dt-bindings: chosen: document kaslr-seed propertyKees Cook1-2/+24
Document the /chosen/kaslr-seed property (and its interaction with the EFI_RNG_PROTOCOL API). Thanks to Ard for clarifications.

2017-06-22of: update ePAPR references to point to Devicetree SpecificationFrank Rowand1-1/+2
The Devicetree Specification has superseded the ePAPR as the base specification for bindings. Update files in Documentation to reference the new document. First reference to ePAPR in Documentation/devicetree/bindings/arm/cci.txt is generic, remove it. Some files are not updated because there is no hypervisor chapter in the Devicetree Specification: Documentation/devicetree/bindings/powerpc/fsl/msi-pic.txt Documenation/virtual/kvm/api.txt Documenation/virtual/kvm/ppc-pv.txt Signed-off-by: Frank Rowand <frank.rowand@sony.com> Signed-off-by: Rob Herring <robh@kernel.org>
2017-04-05Documentation: dt: chosen properties for arm64 kdumpJames Morse1-0/+45
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.

2015-10-28powerpc/book3e-64/kexec: Enable SMP releaseScott Wood1-0/+8
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
2014-12-04of: Add bindings for chosen node, stdout-pathLeif Lindholm1-0/+46
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.
