2020-09-02hw/block/nvme: verify validity of prp lists in the cmbKlaus Jensen1-1/+13
Before this patch the device already supported PRP lists in the CMB, but it did not check for the validity of it nor announced the support in the Identify Controller data structure LISTS field. If some of the PRPs in a PRP list are in the CMB, then ALL entries must be there. This patch makes sure that requirement is verified as well as properly announcing support for PRP lists in the CMB.

Since the device does not have any persistent state storage, no features are "saveable" and setting the Save (SV) field in any Set Features command will result in a Feature Identifier Not Saveable status code. Similarly, if the Select (SEL) field is set to request saved values, the devices will (as it should) return the default values instead.

Note that the LPA field in the Identify Controller data structure intentionally has bit 0 cleared because there is no namespace specific information in the SMART / Health information log page.

2020-09-01hw/arm/sbsa-ref: add "reg" property to DT cpu nodesLeif Lindholm1-6/+23
The sbsa-ref platform uses a minimal device tree to pass amount of memory as well as number of cpus to the firmware. However, when dumping that minimal dtb (with -M sbsa-virt,dumpdtb=<file>), the resulting blob generates a warning when decompiled by dtc due to lack of reg property. Add a simple reg property per cpu, representing a 64-bit MPIDR_EL1. This also ends up being cleaner than having the firmware calculating its own IDs for generating APCI.
