misc: aspeed_scu: Update AST2600 silicon id register
hw/arm/aspeed: Add machine properties to define the flash models
hw/arm/aspeed: Map the UART5 device unconditionally
Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
Aspeed have released an updated datasheet (v7) containing the silicon id
for the AST2600 A2. It looks like this:
SCU004 SCU014
AST2600-A0 0x05000303 0x05000303
AST2600-A1 0x05010303 0x05010303
AST2600-A2 0x05010303 0x05020303
AST2620-A1 0x05010203 0x05010203
AST2620-A2 0x05010203 0x05020203
The SCU004 (silicon id 1) value matches SCU014 for A0, but for
subsequent revisions it is hard coded to the A1 value.
Qemu effectively dropped support for the A0 in 7582591ae7 ("aspeed:
Support AST2600A1 silicon revision") as the A0 reset table was removed,
so it makes sense to only support the behaviour of A1 and onwards.

Previous patch introduced a performance warning being logged on host
side if client connected with an 'msize' <= 8192. Disable this
performance warning for the synth driver to prevent that warning from
being printed whenever the 9pfs (qtest) test cases are running.
Introduce a new export flag V9FS_NO_PERF_WARN for that purpose, which
might also be used to disable such warnings from the CLI in future.
We could have also prevented the warning by simply raising P9_MAX_SIZE
in virtio-9p-test.c to any value larger than 8192, however in the
context of test cases it makes sense running for edge cases, which
includes the lowest 'msize' value supported by the server which is
4096, hence we want to preserve an msize of 4096 for the test client.

It is essential to choose a reasonable high value for 'msize' to avoid
severely degraded file I/O performance. This parameter can only be
chosen on client/guest side, and a Linux client defaults to an 'msize'
of only 8192 if the user did not explicitly specify a value for 'msize',
which results in very poor file I/O performance.
Unfortunately many users are not aware that they should specify an
appropriate value for 'msize' to avoid severe performance issues, so
log a performance warning (with a QEMU wiki link explaining this issue
in detail) on host side in that case to make it more clear.
Currently a client cannot automatically pick a reasonable value for
'msize', because a good value for 'msize' depends on the file I/O
potential of the underlying storage on host side, i.e. a feature
invisible to the client, and even then a user would still need to trade
off between performance profit and additional RAM costs, i.e. with
growing 'msize' (RAM occupation), performance still increases, but
performance delta will shrink continuously.

When booting directly into a kernel, bypassing the boot loader, the CPU and
UART clocks are not set up correctly. This makes the system appear very
slow, and causes the initrd boot test to fail when optimization is off.
The UART clock must run at 24 MHz. The default 25 MHz reference clock
cannot achieve this, so switch to PLL2/2 @ 480 MHz, which works
perfectly with the default /20 divider.
The CPU clock should run at 800 MHz, so switch it to PLL1/2. PLL1 runs
at 800 MHz by default, so we need to double the feedback divider as well
to make it run at 1600 MHz (so PLL1/2 runs at 800 MHz).
We don't bother checking for PLL lock because we know our emulated PLLs
lock instantly.

This patch includes little more than the bare minimum needed to boot a
Linux kernel built with NPCM7xx support in direct-kernel mode:
- Two Cortex-A9 CPU cores with built-in periperhals.
- Global Configuration Registers.
- Clock Management.
- 3 Timer Modules with 5 timers each.
- 4 serial ports.
The chips themselves have a lot more features, some of which will be

The NPCM730 and NPCM750 SoCs have three timer modules each holding five
timers and some shared registers (e.g. interrupt status).
Each timer runs at 25 MHz divided by a prescaler, and counts down from a
configurable initial value to zero. When zero is reached, the interrupt
flag for the timer is set, and the timer is disabled (one-shot mode) or
reloaded from its initial value (periodic mode).
This implementation is sufficient to boot a Linux kernel configured for
NPCM750. Note that the kernel does not seem to actually turn on the
interrupts.

Enough functionality to boot the Linux kernel has been implemented. This
includes:
- Correct power-on reset values so the various clock rates can be
accurately calculated.
- Clock enables stick around when written.
In addition, a best effort attempt to implement SECCNT and CNTR25M was
made even though I don't think the kernel needs them.

Implement a device model for the System Global Control Registers in the
NPCM730 and NPCM750 BMC SoCs.
This is primarily used to enable SMP boot (the boot ROM spins reading
the SCRPAD register) and DDR memory initialization; other registers are
best effort for now.
The reset values of the MDLR and PWRON registers are determined by the
SoC variant (730 vs 750) and board straps respectively.

Implement a model of the MPS2 with the AN500 firmware. This is
similar to the AN385, with the following differences:
* Cortex-M7 CPU
* PSRAM is at 0x6000_0000
* Ethernet is at 0xa000_0000
* No zbt_boot_ctrl remapping of the low 16K

It is the responsibility of board code for an armv7m system to set
system_clock_scale appropriately for the CPU speed of the core.
If it forgets to do this, then QEMU will hang if the guest tries
to use the systick timer in the "tick at the CPU clock frequency" mode.
We forgot that in a couple of our boards (see commits ce4f70e81e,
e7e5a9595a). Add an assertion in the systick reset method so
we don't let any new boards in with the same bug.

qemu_hexdump()'s pointer to the buffer and length of the
buffer are closely related arguments but are widely separated
in the argument list order (also, the format of <stdio.h>
function prototypes is usually to have the FILE* argument
coming first).
Reorder the arguments as "fp, prefix, buf, size" which is
more logical.

At present the PHY address of the PHY connected to GEM is hard-coded
to either 23 (BOARD_PHY_ADDRESS) or 0. This might not be the case for
all boards. Add a new 'phy-addr' property so that board can specify
the PHY address for each GEM instance.

On the Icicle Kit board, the HSS firmware utilizes the on-chip DMA
controller to move the 2nd stage bootloader in the system memory.
Let's connect a DMA controller to Microchip PolarFire SoC.

Microchip PolarFire SoC integrates a DMA engine that supports:
* Independent concurrent DMA transfers using 4 DMA channels
* Generation of interrupts on various conditions during execution
which is actually an IP reused from the SiFive FU540 chip.
This creates a model to support both polling and interrupt modes.

Microchip PolarFire SoC integrates one Cadence SDHCI controller.
On the Icicle Kit board, one eMMC chip and an external SD card
connect to this controller depending on different configuration.
As QEMU does not support eMMC yet, we just emulate the SD card
configuration. To test this, the Hart Software Services (HSS)
should choose the SD card configuration:
$ cp boards/icicle-kit-es/def_config.sdcard .config
$ make BOARD=icicle-kit-es
The SD card image can be built from the Yocto BSP at:
https://github.com/polarfire-soc/meta-polarfire-soc-yocto-bsp
Note the generated SD card image should be resized before use:
$ qemu-img resize /path/to/sdcard.img 4G
Launch QEMU with the following command:
$ qemu-system-riscv64 -nographic -M microchip-icicle-kit -sd sdcard.img

Cadence SD/SDIO/eMMC Host Controller (SD4HC) is an SDHCI compatible
controller. The SDHCI compatible registers start from offset 0x200,
which are called Slot Register Set (SRS) in its datasheet.
This creates a Cadence SDHCI model built on top of the existing
generic SDHCI model. Cadence specific Host Register Set (HRS) is
implemented to make guest software happy.

This is an initial support for Microchip PolarFire SoC Icicle Kit.
The Icicle Kit board integrates a PolarFire SoC, with one SiFive's
E51 plus four U54 cores and many on-chip peripherals and an FPGA.
For more details about Microchip PolarFire Soc, please see:
https://www.microsemi.com/product-directory/soc-fpgas/5498-polarfire-soc-fpga
Unlike SiFive FU540, the RISC-V core resect vector is at 0x20220000.
The following perepherals are created as an unimplemented device:
- Bus Error Uint 0/1/2/3/4
- L2 cache controller
- SYSREG
- MPUCFG
- IOSCBCFG
More devices will be added later.
The BIOS image used by this machine is hss.bin, aka Hart Software
Services, which can be built from:
https://github.com/polarfire-soc/hart-software-services
To launch this machine:
$ qemu-system-riscv64 -nographic -M microchip-icicle-kit
The memory is set to 1 GiB by default to match the hardware.
A sanity check on ram size is performed in the machine init routine
to prompt user to increase the RAM size to > 1 GiB when less than
1 GiB ram is detected.

Now that we have the newly introduced 'resetvec' property in the
RISC-V CPU and HART, instead of hard-coding the reset vector addr
in the CPU's instance_init(), move that to riscv_cpu_realize()
based on the configured property value from the RISC-V machines.

RISC-V machines do not instantiate RISC-V CPUs directly, instead
they do that via the hart array. Add a new property for the reset
vector address to allow the value to be passed to the CPU, before
CPU is realized.
