reserved-memory device tree nodes ================================= OPAL exposes reserved memory through a top-level reserved-memory node, containing subnodes that represent each reserved memory region. This follows the Linux specification for the /reserved-memory node, described in the kernel source tree, in: Documentation/devicetree/bindings/reserved-memory/reserved-memory.txt The top-level /reserved-memory node contains: :: #size-cells = <2> #address-cells = <2> Addresses and sizes are all 64-bits. ``ranges`` the empty ranges node indicates no translation of physical addresses in the subnodes. The sub-nodes under the /reserved-memory node contain: ``reg =
`` the address and size of the reserved memory region. The address and size values are two cells each, as signified by the top-level ``#{address,size}-cells`` ``ibm,prd-label = "string"`` a string token for use by the prd system. Specific ranges may be used by prd - those will be referenced by this label.
