hw/misc: Introduce AMD/Xilix Versal TRNG device
This adds a non-cryptographic grade implementation of the
model for the True Random Number Generator (TRNG) component
in AMD/Xilinx Versal device family.
This implements all 3 modes defined by the actual hardware
specs, all of which selectable by guest software at will
at anytime:
1) PRNG mode, in which the generated sequence is required to
be reproducible after reseeded by the same 384-bit value
as supplied by guest software.
2) Test mode, in which the generated sequence is required to
be reproducible ater reseeded by the same 128-bit test
seed supplied by guest software.
3) TRNG mode, in which non-reproducible sequence is generated
based on periodic reseed by a suitable entropy source.
This model is only intended for non-real world testing of
guest software, where cryptographically strong PRNG or TRNG
is not needed.
This model supports versions 1 & 2 of the device, with
default to be version 2; the 'hw-version' uint32 property
can be set to 0x0100 to override the default.
Other implemented properties:
- 'forced-prng', uint64
When set to non-zero, mode 3's entropy source is implemented
as a deterministic sequence based on the given value and other
deterministic parameters.
This option allows the emulation to test guest software using
mode 3 and to reproduce data-dependent defects.
- 'fips-fault-events', uint32, bit-mask
bit 3: Triggers the SP800-90B entropy health test fault irq
bit 1: Triggers the FIPS 140-2 continuous test fault irq
