Finally the rules for compiling the test have to change because it is possible not to have CONFIG_STELLARIS (required for the lm3s811evb machine) while still having CONFIG_CMSDK_APB_WATCHDOG and the test will fail. Due to the addition of the MPS2 machine CONFIG_MPS2 becomes also a dependency for the test compilation.

As described in: https://developer.arm.com/documentation/ddi0479/d/apb-components/apb-watchd= og/programmers-model The new tests have to target an MPS2 machine because the original machine used by the test (stellaris) has a variation of the cmsdk_apb_watchdog that locks INTEN when it is programmed to 1. The stellaris machine also does not reproduce the problem of the counter running out of cold reset due to the way the clocks are initialized.

This means that we forgot to update it to handle some newer architectural features, including: * handling of SCTLR.{UWXN,WXN} * handling of SCR.SIF Make the short-format descriptor code call the same get_S1prot() that we already use for the LPAE descriptor format. This makes the code simpler and means it now correctly honours the WXN/UWXN and SIF bits.

However (largely because they originally came from the Linux kernel) the bit array storage is an array of 'unsigned long'. This is OK for the kernel and even for parts of QEMU where we don't really care about the underlying storage format, but it is not good for devices, where we often want to expose the storage to the guest and so need a type that is not variably-sized between host OSes. We already have a workaround for this in the GICv3 model: arm_gicv3_common.h defines equivalents of the bit operations that work on uint32_t. It turns out that we should also be using something similar in hw/intc/loongarch_extioi.c, which currently casts a pointer to a uint32_t array to 'unsigned long *' in extio_setirq(), which is both undefined behaviour and not correct on a big-endian host. Define equivalents of the set_bit() function family which work with a uint32_t array. (Cc stable because we're about to provide a bugfix to loongarch_extioi which will depend on this commit.)

When we added the trace events in target/arm/hvf/ we forgot to create this file and instead hvf.c directly includes trace/trace-target_arm_hvf.h. Create the standard trace.h file to bring this into line with the convention.
