2023-02-07hw/arm/aspeed_ast10x0: Add TODO comment to use Cortex-M4FPhilippe Mathieu-Daudé
This SoC uses a Cortex-M4F. QEMU only implements a M4, which is good enough. Add a TODO note in case the M4F is added.

Avoid confusing two different things: - the WDT I/O region size ('iosize') - at which offset the SoC map the WDT ('offset') While it is often the same, we can map smaller region sizes at larger offsets. Here we are interested in the I/O region size, so rename as 'iosize'.

2022-07-14aspeed: Refactor UART init for multi-SoC machinesPeter Delevoryas
This change moves the code that connects the SoC UART's to serial_hd's to the machine. It makes each UART a proper child member of the SoC, and then allows the machine to selectively initialize the chardev for each UART with a serial_hd. This should preserve backwards compatibility, but also allow multi-SoC boards to completely change the wiring of serial devices from the command line to specific SoC UART's. This also removes the uart-default property from the SoC, since the SoC doesn't need to know what UART is the "default" on the machine anymore. I tested this using the images and commands from the previous refactoring, and another test image for the ast1030: wget https://github.com/facebook/openbmc/releases/download/v2021.49.0/fuji.mtd wget https://github.com/facebook/openbmc/releases/download/v2021.49.0/wedge100.mtd wget https://github.com/peterdelevoryas/OpenBIC/releases/download/oby35-cl-2022.13.01/Y35BCL.elf Fuji uses UART1: qemu-system-arm -machine fuji-bmc \ -drive file=fuji.mtd,format=raw,if=mtd \ -nographic ast2600-evb uses uart-default=UART5: qemu-system-arm -machine ast2600-evb \ -drive file=fuji.mtd,format=raw,if=mtd \ -serial null -serial mon:stdio -display none Wedge100 uses UART3: qemu-system-arm -machine palmetto-bmc \ -drive file=wedge100.mtd,format=raw,if=mtd \ -serial null -serial null -serial null \ -serial mon:stdio -display none AST1030 EVB uses UART5: qemu-system-arm -machine ast1030-evb \ -kernel Y35BCL.elf -nographic Fixes: 6827ff20b2975 ("hw: aspeed: Init all UART's with serial devices") Signed-off-by: Peter Delevoryas <peter@pjd.dev> Reviewed-by: Cédric Le Goater <clg@kaod.org> Message-Id: <20220705191400.41632-4-peter@pjd.dev> Signed-off-by: Cédric Le Goater <clg@kaod.org>
2022-07-14aspeed: Create SRAM name from first CPU indexPeter Delevoryas
To support multiple SoC's running simultaneously, we need a unique name for each RAM region. DRAM is created by the machine, but SRAM is created by the SoC, since in hardware it is part of the SoC's internals. We need a way to uniquely identify each SRAM region though, for VM migration. Since each of the SoC's CPU's has an index which identifies it uniquely from other CPU's in the machine, we can use the index of any of the CPU's in the SoC to uniquely identify differentiate the SRAM name from other SoC SRAM's. In this change, I just elected to use the index of the first CPU in each SoC.

2022-06-30hw/misc/aspeed: Add PECI controllerPeter Delevoryas
This introduces a really basic PECI controller that responses to commands by always setting the response code to success and then raising an interrupt to indicate the command is done. This helps avoid getting hit with constant errors if the driver continuously attempts to send a command and keeps timing out. The AST2400 and AST2500 only included registers up to 0x5C, not 0xFC. They supported PECI 1.1, 2.0, and 3.0. The AST2600 and AST1030 support PECI 4.0, which includes more read/write buffer registers from 0x80 to 0xFC to support 64-byte mode. This patch doesn't attempt to handle that, or to create a different version of the controller for the different generations, since it's only implementing functionality that is common to all generations. The basic sequence of events is that the firmware will read and write to various registers and then trigger a command by setting the FIRE bit in the command register (similar to the I2C controller). Then the firmware waits for an interrupt from the PECI controller, expecting the interrupt status register to be filled in with info on what happened. If the command was transmitted and received successfully, then response codes from the host CPU will be found in the data buffer registers.
