[PATCH v4 0/3] hw/misc: Model ASPEED hash and crypto engine

[Joel Stanley]

v4: Rebase on Philippe's memory region cleanup series [1]
    Address feedback from Cédric
    Rework qtest to run on ast2400, ast2500 and ast2600
v3: Rework qtest to not use libqtest-single.h, rebase to avoid LPC
conflicts.
v2: Address review from Andrew and Philippe. Adds a qtest.

[1] 20210312182851.1922972-1-f4bug@amsat.org/">https://lore.kernel.org/qemu-devel/20210312182851.1922972-1-f4bug@amsat.org/

This adds a model for the ASPEED hash and crypto engine (HACE) found on
all supported ASPEED SoCs.

The model uses Qemu's gcrypto API to perform the SHA and MD5 hashing
directly in the machine's emulated memory space, which I found a neat
use of Qemu's features.

It has been tested using u-boot and from Linux userspace, and adds a
qtest for the model running as part of the ast2600-evb, ast2500-evb and
palmetto-bmc (to test ast2400) machines.

Note that the tests will fail without Philippe's series.
