2022-10-24aspeed/smc: Cache AspeedSMCClassCédric Le Goater
Store a reference on the AspeedSMC class under the flash object and use it when accessing the flash contents. Avoiding the class cast checkers in these hot paths improves performance by 10% when running the aspeed avocado tests.

2021-10-12aspeed/smc: Add watchdog Control/Status RegistersCédric Le Goater
The Aspeed SoCs have a dual boot function for firmware fail-over recovery. The system auto-reboots from the second flash if the main flash does not boot successfully within a certain amount of time. This function is called alternate boot (ABR) in the FMC controllers. On AST2400/AST2500, ABR is enabled by hardware strapping in SCU70 to enable the 2nd watchdog timer, on AST2600, through register SCU510. If the boot on the the main flash succeeds, the firmware should disable the 2nd watchdog timer. If not, the BMC is reset and the CE0 and CE1 mappings are swapped to restart the BMC from the 2nd flash. On the AST2600, the ABR registers controlling the 2nd watchdog timer were moved from the watchdog register to the FMC controller and the FMC model should be able to control WDT2 through its own register set. This requires more work. For now, add dummy read/write handlers to let the FW disable the 2nd watchdog without error.

2020-06-15ssi: ssi_auto_connect_slaves() never does anything, dropMarkus Armbruster
ssi_auto_connect_slaves(parent, cs_line, bus) iterates over @parent's QOM children @dev of type TYPE_SSI_SLAVE. It puts these on @bus, and sets cs_line[] to qdev_get_gpio_in_named(dev, SSI_GPIO_CS, 0). Suspicious: there is no protection against overrunning cs_line[]. Turns out it's safe because ssi_auto_connect_slaves() never finds any such children. Its called by realize methods of some (but not all) devices providing an SSI bus, and gets passed the device. SSI slave devices are always created with ssi_create_slave_no_init(), optionally via ssi_create_slave(). This adds them to their SSI bus. It doesn't set their QOM parent. ssi_create_slave_no_init() is always immediately followed by qdev_init_nofail(), with no QOM parent assigned, so device_set_realized() puts the device into the /machine/unattached/ orphanage. None become QOM children of a device providing an SSI bus. ssi_auto_connect_slaves() was added in commit b4ae3cfa57 "ssi: Add slave autoconnect helper". I can't see which slaves it was supposed to connect back then.

When the User mode is configured, it selects automatically the SPI slave device until the CE_STOP_ACTIVE bit is set to 1. When any other modes are configured the device is unselected. The HW logic handles the chip select automatically when the flash is accessed through its AHB window.

Errors are only injected when the property "inject_failure" is set to true as suggested by Philippe. The values below are those to expect from the first flash device of the FMC controller of a palmetto-bmc machine.

2019-09-13aspeed/smc: Add DMA calibration settingsCédric Le Goater
When doing calibration, the SPI clock rate in the CE0 Control Register and the read delay cycles in the Read Timing Compensation Register are set using bit[11:4] of the DMA Control Register.

2019-09-13aspeed/smc: Add support for DMAsCédric Le Goater
The FMC controller on the Aspeed SoCs support DMA to access the flash modules. It can operate in a normal mode, to copy to or from the flash module mapping window, or in a checksum calculation mode, to evaluate the best clock settings for reads. The model introduces two custom address spaces for DMAs: one for the AHB window of the FMC flash devices and one for the DRAM. The latter is populated using a "dram" link set from the machine with the RAM container region.

Improve the naming of the different controller models to ease their generation when initializing the SoC. The rename of the SMC types is breaking migration compatibility.

2019-08-16Clean up inclusion of sysemu/sysemu.hMarkus Armbruster
In my "build everything" tree, changing sysemu/sysemu.h triggers a recompile of some 5400 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). Almost a third of its inclusions are actually superfluous. Delete them. Downgrade two more to qapi/qapi-types-run-state.h, and move one from char/serial.h to char/serial.c. hw/semihosting/config.c, monitor/monitor.c, qdev-monitor.c, and stubs/semihost.c define variables declared in sysemu/sysemu.h without including it. The compiler is cool with that, but include it anyway. This doesn't reduce actual use much, as it's still included into widely included headers. The next commit will tackle that.

2019-08-16Include hw/qdev-properties.h lessMarkus Armbruster
In my "build everything" tree, changing hw/qdev-properties.h triggers a recompile of some 2700 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). Many places including hw/qdev-properties.h (directly or via hw/qdev.h) actually need only hw/qdev-core.h. Include hw/qdev-core.h there instead. hw/qdev.h is actually pointless: all it does is include hw/qdev-core.h and hw/qdev-properties.h, which in turn includes hw/qdev-core.h. Replace the remaining uses of hw/qdev.h by hw/qdev-properties.h. While there, delete a few superfluous inclusions of hw/qdev-core.h. Touching hw/qdev-properties.h now recompiles some 1200 objects.
