4936f38abe target/arm: Convert Neon VQABS, VQNEG to decodetree
Convert the Neon VQABS and VQNEG insns to decodetree.
Since these are the only ones which need cpu_env passing to
the helper, we wrap the helper rather than creating a whole
new do_2misc_env() function.

8ec3de7018 target/arm: Make gen_swap_half() take separate src and dest
Make gen_swap_half() take a source and destination TCGv_i32 rather
than modifying the input TCGv_i32; we're going to want to be able to
use it with the more flexible function signature, and this also
brings it into line with other functions like gen_rev16() and
gen_revsh().

039f4e809a target/arm: Rename NeonGenOneOpFn to NeonGenOne64OpFn
The NeonGenOneOpFn typedef breaks with the pattern of the other
NeonGen*Fn typedefs, because it is a TCGv_i64 -> TCGv_i64 operation
but it does not have '64' in its name. Rename it to NeonGenOne64OpFn,
so that the old name is available for a TCGv_i32 -> TCGv_i32 operation
(which we will need in a subsequent commit).

c7ebab0f16 tests/acceptance: add base class record/replay kernel tests
This patch adds a base for testing kernel boot recording and replaying.
Each test has the phase of recording and phase of replaying.
Virtual machines just boot the kernel and do not interact with
the network.
Structure and image links for the tests are borrowed from boot_linux_console.py
Testing controls the message pattern at the end of the kernel
boot for both record and replay modes. In replay mode QEMU is also
intended to finish the execution automatically.

Acceptance tests can test any piece of the QEMU codebase.
    As such, the directory holding them does not belong to a specific
    subsystem with designated maintainers.

    Each subsystem covered by a test is welcomed to add the test path
    to its section.
    See for example commits 71b290e70, b11785ca2 or 5d480ddde.

Add an entry for to allow reviewers to be notified when acceptance /
integration tests are added or modified.
The designated reviewers are not maintainers, subsystem maintainers
are expected to merge their tests.

06c4cc3660 qht: Fix threshold rate calculation
tests/qht-bench.c:287:29: error: implicit conversion from 'unsigned long'
  to 'double' changes value from 18446744073709551615
  to 18446744073709551616 [-Werror,-Wimplicit-int-float-conversion]
        *threshold = rate * UINT64_MAX;
                          ~ ^~~~~~~~~~

Fix this by splitting the 64-bit constant into two halves,
each of which is individually perfectly representable, the
sum of which produces the correct arithmetic result.

This is very likely just a sticking plaster over some underlying
incorrect code, but it will suppress the warning for the moment.

3eaea6eb4e hw/riscv: sifive_u: Add a dummy DDR memory controller device
It is enough to simply map the SiFive FU540 DDR memory controller
into the MMIO space using create_unimplemented_device(), to make
the upstream U-Boot v2020.07 DDR memory initialization codes happy.

Note we do not generate device tree fragment for the DDR memory
controller. Since the controller data in device tree consumes a
very large space (see fu540-hifive-unleashed-a00-ddr.dtsi in the
U-Boot source), and it is only needed by U-Boot SPL but not any
operating system, we choose not to generate the fragment here.
This also means when testing with U-Boot SPL, the device tree has
to come from U-Boot SPL itself, but not the one generated by QEMU
on the fly. The memory has to be set to 8GiB to match the real
HiFive Unleashed board when invoking QEMU (-m 8G).

With this commit, QEMU can boot U-Boot SPL built for SiFive FU540
all the way up to loading U-Boot proper from MMC:

$ qemu-system-riscv64 -nographic -M sifive_u,msel=6 -m 8G -bios u-boot-spl.bin

U-Boot SPL 2020.07-rc3-00208-g88bd5b1 (Jun 08 2020 - 20:16:10 +0800)
Trying to boot from MMC1
Unhandled exception: Load access fault
EPC: 0000000008009be6 TVAL: 0000000010050014

The above exception is expected because QSPI is unsupported yet.

17aad9f276 hw/riscv: sifive_u: Support different boot source per MSEL pin state
SiFive FU540 SoC supports booting from several sources, which are
controlled using the Mode Select (MSEL[3:0]) pins on the chip.
Typically, the boot process runs through several stages before it
begins execution of user-provided programs.

The SoC supports booting from memory-mapped QSPI flash, which is
how start_in_flash property is used for at present. This matches
MSEL = 1 configuration (QSPI0).

Typical booting flows involve the Zeroth Stage Boot Loader (ZSBL).
It's not necessary for QEMU to implement the full ZSBL ROM codes,
because we know ZSBL downloads the next stage program into the L2
LIM at address 0x8000000 and executes from there. We can bypass
the whole ZSBL execution and use "-bios" to load the next stage
program directly if MSEL indicates a ZSBL booting flow.
