1P9 memory hierarchy 2------------------- 3P9 Nimbus supports direct attached DDR memory through 4 DDR ports per side 4of the processor. Device tree contains memory hierarchy so that one can 5traverse from chip to DIMM like below: 6 7 xscom@<addr>/mcbist@<mcbist_id>/mcs@<mcs_id>/mca@<mca_id>/dimm@<resource_id> 8 9Example of dimm node: 10.. code-block:: dts 11 12 dimm@d00e { 13 memory-id = <0xc>; /* DRAM Device Type. 0xc = DDR4 */ 14 product-version = <0x32>; /* Module Revision Code */ 15 device_type = "memory-dimm-ddr4"; 16 serial-number = <0x15d9ad1c>; 17 status = "okay"; 18 size = <0x4000>; 19 phandle = <0xd2>; 20 ibm,loc-code = "UOPWR.0000000-Node0-DIMM14"; 21 part-number = "36ASF2G72PZ-2G6B2 "; 22 reg = <0xd00e>; 23 manufacturer-id = <0x802c>; /* Vendor ID, we can get vendor name from this ID */ 24 }; 25
