For supporting the SD controller selection (alternate function of GPIOs 48-53), the bcm2835_gpio now exposes an sdbus. It also has a link to both the sdbus of sdhci and sdhost controllers, and the card is reparented from one bus to another when the alternate function of GPIOs 48-53 is modified.

Use direct memory operations, since the pointers are aligned. While BS=2 (16 bytes, 1 tag) is a legal setting, that requires an atomic store of one nibble. This is not difficult, but there is also no point in supporting it until required. Note that cortex-a710 sets GM blocksize to match its cacheline size of 64 bytes. I expect many implementations will also match the cacheline, which makes 16 bytes very unlikely.

When running Linux directly, QEMU is emulating a PSCI interface that UBOOT is installing at boot time and therefore the fact that the SRC device is unimplemented is hidden as Qemu respond directly to PSCI requets without using the SRC device. But if you try to run a more bare metal application (maybe uboot itself), then it is not possible to start the secondary CPU as the SRC is an unimplemented device. This patch adds the ability to start the secondary CPU through the SRC device so that you can use this feature in bare metal applications.

Currently we do this in two places -- we set a few flags in arm_cpu_post_init() because we need them to decide which properties to create on the CPU object, and then we do the rest in arm_cpu_realizefn(). However, this is fragile, because it's easy to add a new property and not notice that this means that an X-implies-Y check now has to move from realize to post-init. As a specific example, the pmsav7-dregion property is conditional on ARM_FEATURE_PMSA && ARM_FEATURE_V7, which means it won't appear on the Cortex-M33 and -M55, because they set ARM_FEATURE_V8 and rely on V8-implies-V7, which doesn't happen until the realizefn. Move all of these X-implies-Y checks into a new function, which we call at the top of arm_cpu_post_init(), so the feature bits are available at that point. This does now give us the reverse issue, that if there's a feature bit which is enabled or disabled by the setting of a property then then X-implies-Y features that are dependent on that property need to be in realize, not in this new function. But the only one of those is the "EL3 implies VBAR" which is already in the right place, so putting things this way round seems better to me.

Add properties mpu-ns-regions and mpu-s-regions to the ARMV7M object, matching the ability of hardware to configure the number of Secure and NonSecure regions separately. Our actual CPU implementation doesn't currently support that, and it happens that none of the MPS boards we model set the number of regions differently for Secure vs NonSecure, so we provide an interface to the boards and SoCs that won't need to change if we ever do add that functionality in future, but make it an error to configure the two properties to different values. (The property name on the CPU is the somewhat misnamed-for-M-profile "pmsav7-dregion", so we don't follow that naming convention for the properties here. The TRM doesn't say what the CPU configuration variable names are, so we pick something, and follow the lowercase convention we already have for properties here.)

The MPS2/MPS3 FPGA images don't override these except in the case of AN547, which uses 16 MPU regions. Define properties on the ARMSSE object for the MPU regions (using the same names as the documented RTL configuration settings, and following the pattern we already have for this device of using all-caps names as the RTL does), and set them in the board code. We don't actually need to override the default except on AN547, but it's simpler code to have the board code set them always rather than tracking which board subtypes want to set them to a non-default value separately from what that value is. Tho overall effect is that for mps2-an505, mps2-an521 and mps3-an524 we now correctly use 8 MPU regions, while mps3-an547 stays at its current 16 regions. It's possible some guest code wrongly depended on the previous incorrectly modeled number of memory regions. (Such guest code should ideally check the number of regions via the MPU_TYPE register.) The old behaviour can be obtained with additional -global arguments to QEMU: For mps2-an521 and mps2-an524: -global sse-200.CPU0_MPU_NS=16 -global sse-200.CPU0_MPU_S=16 -global sse-200.CPU1_MPU_NS=16 -global sse-200.CPU1_MPU_S=16 For mps2-an505: -global sse-200.CPU0_MPU_NS=16 -global sse-200.CPU0_MPU_S=16 NB that the way the implementation allows this use of -global is slightly fragile: if the board code explicitly sets the properties on the sse-200 object, this overrides the -global command line option. So we rely on: - the boards that need fixing all happen to use the SSE defaults - we can write the board code to only set the property if it is different from the default, rather than having all boards explicitly set the property - the board that does need to use a non-default value happens to need to set it to the same value (16) we previously used This works, but there are some kinds of refactoring of the mps2-tz.c code that would break the support for -global here.
