Peter Maydell 50b52b18cd hw/arm/mps2: Update old infocenter.arm.com URLs
Update old infocenter.arm.com URLs to the equivalent developer.arm.com
ones (the old URLs should redirect, but we might as well avoid the
redirection notice, and the new URLs are pleasantly shorter).

This commit covers the links to the MPS2 board TRM, the various
Application Notes, the IoTKit and SSE-200 documents.

Rename ESP_CMDBUF_SZ to ESP_CMDFIFO_SZ and cmdbuf_cdb_offset to cmdfifo_cdb_offset
to indicate that the command buffer type has changed from an array to a Fifo8.

This also enables us to remove the ESPState field cmdlen since the command length
is now simply the number of elements used in cmdfifo.

Mark Cave-Ayland 799d90d818 esp: transition to message out phase after SATN and stop command
The SCSI bus should remain in the message out phase after the SATN and stop
command rather than transitioning to the command phase. A new ESPState variable
cmdbuf_cdb_offset is added which stores the offset of the CDB from the start
of cmdbuf when accumulating extended message out phase data.

Currently any extended message out data is discarded in do_cmd() before the CDB
is processed in do_busid_cmd().

Mark Cave-Ayland 4aaa6ac383 esp: remove old deferred command completion mechanism
Commit ea84a44250 "scsi: esp: Defer command completion until previous interrupts
have been handled" provided a mechanism to delay the command completion interrupt
until ESP_RINTR is read after the command has completed.

With the previous fixes for latching the ESP_RINTR bits and deferring the setting
of the command completion interrupt for incoming data to the SCSI callback, this
workaround is no longer required and can be removed.

Mark Cave-Ayland 4e78f3bf35 esp: defer command completion interrupt on incoming data transfers
The MacOS toolbox ROM issues a command to the ESP controller as part of its
"FAST" SCSI routines and then proceeds to read the incoming data soon after
receiving the command completion interrupt.

Unfortunately due to SCSI block transfers being asynchronous the incoming data
may not yet be present causing an underflow error. Resolve this by waiting for
the SCSI subsystem transfer_data callback before raising the command completion
interrupt.

ESP SCSI commands are already accumulated in cmdbuf and so there is no need to
keep a separate pdma_buf buffer. Accumulate SCSI commands for PDMA transfers in
cmdbuf instead of pdma_buf so update cmdlen accordingly and change pdma_origin

This commit also removes a stray memcpy() from get_cmd() which is a no-op because
cmdlen is always zero at the start of a command.

Mark Cave-Ayland 0bd005be78 esp: add vmstate_esp version to embedded ESPState
The QOM object representing ESPState is currently embedded within both the
SYSBUS_ESP and PCI_ESP devices with migration state handled by embedding
vmstate_esp within each device using VMSTATE_STRUCT.

Since the vmstate_esp fields are embedded directly within the migration
stream, the incoming vmstate_esp version_id is lost. The only version information
available is that from vmstate_sysbus_esp_scsi and vmstate_esp_pci_scsi, but
those versions represent their respective devices and not that of the underlying
ESPState.

Resolve this by adding a new version-dependent field in vmstate_sysbus_esp_scsi
and vmstate_esp_pci_scsi which stores the vmstate_esp version_id field within
ESPState to be used to allow migration from older QEMU versions.

Finally bump the vmstate_esp version to 5 to cover the upcoming ESPState changes
within this patch series.

Each board in this family can have minor differences in the meaning

behaviour conditional on the part-number field of the SCC_ID register
which the board code already passes us.

For the AN524, the differences are:
 * CFG3 is reserved rather than being board switches
 * CFG5 is a new register ("ACLK Frequency in Hz")
 * CFG6 is a new register ("Clock divider for BRAM")

We implement both of the new registers as reads-as-written.

Markus Armbruster d71a243220 error: Fix "Converting to ERRP_GUARD()" doc on "valid at return"
Setting errp = NULL is wrong: the automatic error propagation still
propagates the dangling pointer _auto_errp_prop.local_err.  We need to
set *errp = NULL to clear the dangling pointer.

This adds the QSPI2 controller to the SoC, and connects an SD
card to it. The generation of corresponding device tree source
fragment is also added.

Specify machine property `msel` to 11 to boot the same upstream
U-Boot SPL and payload image for the SiFive HiFive Unleashed board.
Note subsequent payload is stored in the SD card image.

Bin Meng 145b299139 hw/riscv: sifive_u: Add QSPI0 controller and connect a flash
This adds the QSPI0 controller to the SoC, and connects an ISSI
25WP256 flash to it. The generation of corresponding device tree
source fragment is also added.

Since the direct memory-mapped mode is not supported by the SiFive
SPI model, the <reg> property does not populate the second group
which represents the memory mapped address of the SPI flash.

With this commit, upstream U-Boot for the SiFive HiFive Unleashed
board can boot on QEMU 'sifive_u' out of the box. This allows users
to develop and test the recommended RISC-V boot flow with a real
world use case: ZSBL (in QEMU) loads U-Boot SPL from SPI flash to
L2LIM, then U-Boot SPL loads the payload from SPI flash that is
combined with OpenSBI fw_dynamic firmware and U-Boot proper.

Specify machine property `msel` to 6 to allow booting from the SPI
flash. U-Boot spl is directly loaded via `-bios`, and subsequent
payload is stored in the SPI flash image. Example command line:

$ qemu-system-riscv64 -nographic -M sifive_u,msel=6 -smp 5 -m 8G \
    -bios u-boot-spl.bin -drive file=spi-nor.img,if=mtd
