hw/gpio: Add basic Aspeed GPIO model for AST2400 and AST2500 GPIO pins are arranged in groups of 8 pins labeled A,B,..,Y,Z,AA,AB,AC. (Note that the ast2400 controller only goes up to group AB). A set has four groups (except set AC which only has one) and is referred to by the groups it is composed of (eg ABCD,EFGH,...,YZAAAB). Each set is accessed and controlled by a bank of 14 registers. These registers operate on a per pin level where each bit in the register corresponds to a pin, except for the command source registers. The command source registers operate on a per group level where bits 24, 16, 8 and 0 correspond to each group in the set. eg. registers for set ABCD: |D7...D0|C7...C0|B7...B0|A7...A0| <- GPIOs |31...24|23...16|15....8|7.....0| <- bit position Note that there are a couple of groups that only have 4 pins. There are two ways that this model deviates from the behaviour of the actual controller: (1) The only control source driving the GPIO pins in the model is the ARM model (as there currently aren't models for the LPC or Coprocessor). (2) None of the registers in the model are reset tolerant (needs integration with the watchdog).

hw/gpio: Add basic Aspeed GPIO model for AST2400 and AST2500 GPIO pins are arranged in groups of 8 pins labeled A,B,..,Y,Z,AA,AB,AC. (Note that the ast2400 controller only goes up to group AB). A set has four groups (except set AC which only has one) and is referred to by the groups it is composed of (eg ABCD,EFGH,...,YZAAAB). Each set is accessed and controlled by a bank of 14 registers. These registers operate on a per pin level where each bit in the register corresponds to a pin, except for the command source registers. The command source registers operate on a per group level where bits 24, 16, 8 and 0 correspond to each group in the set. eg. registers for set ABCD: |D7...D0|C7...C0|B7...B0|A7...A0| <- GPIOs |31...24|23...16|15....8|7.....0| <- bit position Note that there are a couple of groups that only have 4 pins. There are two ways that this model deviates from the behaviour of the actual controller: (1) The only control source driving the GPIO pins in the model is the ARM model (as there currently aren't models for the LPC or Coprocessor). (2) None of the registers in the model are reset tolerant (needs integration with the watchdog).

A set has four groups (except set AC which only has one) and is referred to by the groups it is composed of (eg ABCD,EFGH,...,YZAAAB). Each set is accessed and controlled by a bank of 14 registers. These registers operate on a per pin level where each bit in the register corresponds to a pin, except for the command source registers. The command source registers operate on a per group level where bits 24, 16, 8 and 0 correspond to each group in the set. eg. registers for set ABCD: |D7...D0|C7...C0|B7...B0|A7...A0| <- GPIOs |31...24|23...16|15....8|7.....0| <- bit position Note that there are a couple of groups that only have 4 pins. There are two ways that this model deviates from the behaviour of the actual controller: (1) The only control source driving the GPIO pins in the model is the ARM model (as there currently aren't models for the LPC or Coprocessor). (2) None of the registers in the model are reset tolerant (needs integration with the watchdog).

The "when != lbl:" is necessary to avoid transforming if (fun(args, &err)) { goto out } ... out: error_propagate(errp, err); even though other paths to label out still need the error_propagate(). For an actual example, see sclp_realize(). Without the "when strict", Coccinelle transforms vfio_msix_setup(), incorrectly. I don't know what exactly "when strict" does, only that it helps here. The match of return is narrower than what I want, but I can't figure out how to express "return where the operand doesn't use @err". For an example where it's too narrow, see vfio_intx_enable(). Silently fails to convert hw/arm/armsse.c, because Coccinelle gets confused by ARMSSE being used both as typedef and function-like macro there. Converted manually. Line breaks tidied up manually. One nested declaration of @local_err deleted manually. Preexisting unwanted blank line dropped in hw/riscv/sifive_e.c.

hw/gpio: Add basic Aspeed GPIO model for AST2400 and AST2500 GPIO pins are arranged in groups of 8 pins labeled A,B,..,Y,Z,AA,AB,AC. (Note that the ast2400 controller only goes up to group AB). A set has four groups (except set AC which only has one) and is referred to by the groups it is composed of (eg ABCD,EFGH,...,YZAAAB). Each set is accessed and controlled by a bank of 14 registers. These registers operate on a per pin level where each bit in the register corresponds to a pin, except for the command source registers. The command source registers operate on a per group level where bits 24, 16, 8 and 0 correspond to each group in the set. eg. registers for set ABCD: |D7...D0|C7...C0|B7...B0|A7...A0| <- GPIOs |31...24|23...16|15....8|7.....0| <- bit position Note that there are a couple of groups that only have 4 pins. There are two ways that this model deviates from the behaviour of the actual controller: (1) The only control source driving the GPIO pins in the model is the ARM model (as there currently aren't models for the LPC or Coprocessor). (2) None of the registers in the model are reset tolerant (needs integration with the watchdog).

qom: Drop parameter @errp of object_property_add() & friends The only way object_property_add() can fail is when a property with the same name already exists. Since our property names are all hardcoded, failure is a programming error, and the appropriate way to handle it is passing &error_abort. Same for its variants, except for object_property_add_child(), which additionally fails when the child already has a parent. Parentage is also under program control, so this is a programming error, too. We have a bit over 500 callers. Almost half of them pass &error_abort, slightly fewer ignore errors, one test case handles errors, and the remaining few callers pass them to their own callers. The previous few commits demonstrated once again that ignoring programming errors is a bad idea. Of the few ones that pass on errors, several violate the Error API. The Error ** argument must be NULL, &error_abort, &error_fatal, or a pointer to a variable containing NULL. Passing an argument of the latter kind twice without clearing it in between is wrong: if the first call sets an error, it no longer points to NULL for the second call. ich9_pm_add_properties(), sparc32_ledma_realize(), sparc32_dma_realize(), xilinx_axidma_realize(), xilinx_enet_realize() are wrong that way. When the one appropriate choice of argument is &error_abort, letting users pick the argument is a bad idea. Drop parameter @errp and assert the preconditions instead. There's one exception to "duplicate property name is a programming error": the way object_property_add() implements the magic (and undocumented) "automatic arrayification". Don't drop @errp there. Instead, rename object_property_add() to object_property_try_add(), and add the obvious wrapper object_property_add().
