for passing data between firmware and the operating system, like boot
arguments. Data in the chosen node does not represent the hardware.
+The following properties are recognized:
-stdout-path property
---------------------
+
+kaslr-seed
+-----------
+
+This property is used when booting with CONFIG_RANDOMIZE_BASE as the
+entropy used to randomize the kernel image base address location. Since
+it is used directly, this value is intended only for KASLR, and should
+not be used for other purposes (as it may leak information about KASLR
+offsets). It is parsed as a u64 value, e.g.
+
+/ {
+ chosen {
+ kaslr-seed = <0xfeedbeef 0xc0def00d>;
+ };
+};
+
+Note that if this property is set from UEFI (or a bootloader in EFI
+mode) when EFI_RNG_PROTOCOL is supported, it will be overwritten by
+the Linux EFI stub (which will populate the property itself, using
+EFI_RNG_PROTOCOL).
+
+stdout-path
+-----------
Device trees may specify the device to be used for boot console output
with a stdout-path property under /chosen, as described in the Devicetree

PCI bus bridges have standardized Device Tree bindings:
PCI Bus Binding to: IEEE Std 1275-1994
-http://www.firmware.org/1275/bindings/pci/pci2_1.pdf
+http://www.devicetree.org/open-firmware/bindings/pci/pci2_1.pdf
And for the interrupt mapping part:
Open Firmware Recommended Practice: Interrupt Mapping
-http://www.firmware.org/1275/practice/imap/imap0_9d.pdf
+http://www.devicetree.org/open-firmware/practice/imap/imap0_9d.pdf
