Sigh.. https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/devicetree/bindings/dts-coding-style.rst#n117
1. "compatible" <- not present
2. "reg" <- present
3. "ranges" <- not present
4. Standard/common properties (defined by common bindings, e.g. without
vendor-prefixes) <- bootph-all and device_type
5. Vendor-specific properties -> not present
6. "status" (if applicable) -> not present
7. Child nodes, where each node is preceded with a blank line -> not
present
So:
/* 16G RAM */
reg = <0x00000000 0x80000000 0x00000000 0x80000000>,
<0x00000008 0x80000000 0x00000003 0x80000000>;
device_type = "memory";
bootph-all;
??
