QEMU MMU tracing showed that there might be something wrong with
its Xtensa MMU implementation, which result in access violation
when running samples/userspace/hello_world_user.
Here is the MMU trace from QEMU from failed runs:
get_pte: autorefill(00109020): PTE va = 20000424, pa = 0010c424
get_physical_addr_mmu: autorefill(00109020): 00109000 -> 00109006
xtensa_cpu_tlb_fill(00109020, 1, 0) -> 00109020, ret = 0
xtensa_cpu_tlb_fill(00109028, 1, 0) -> 00109028, ret = 0
xtensa_cpu_tlb_fill(00109014, 0, 2) -> 00103050, ret = 26
The place where it fails is during reading from 0x109014.
From the trace above, the auto-refill maps 0x109000 correctly
with ring 0 and RW access with WB cache (which should be correct
the first time under kernel mode). The page 0x109000 is the libc
partition which needs to be accessible from user thread.
However, when accessing that page, the returned physical address
became 0x103050 (and resulting in load/store access violation).
We always identity map memory pages so it should never return
a different physical address.
After forcing TLB invalidation during page table swaps, the MMU
trace is:
get_pte: autorefill(00109020): PTE va = 20000424, pa = 0010c424
get_physical_addr_mmu: autorefill(00109020): 00109000 -> 00109006
xtensa_cpu_tlb_fill(00109020, 1, 0) -> 00109020, ret = 0
get_pte: autorefill(00109028): PTE va = 21000424, pa = 0010e424
get_physical_addr_mmu: autorefill(00109028): 00109000 -> 00109022
xtensa_cpu_tlb_fill(00109028, 1, 0) -> 00109028, ret = 0
get_pte: autorefill(00109014): PTE va = 21000424, pa = 0010e424
get_physical_addr_mmu: autorefill(00109014): 00109000 -> 00109022
xtensa_cpu_tlb_fill(00109014, 0, 2) -> 00109014, ret = 0
xtensa_cpu_tlb_fill(00109020, 0, 0) -> 00109020, ret = 0
Here, when the same page is accessed, it got the correct PTE
entry, which is ring 2 with RW access mode (but no cache).
Actually accessing the variable via virtual address returns
the correct physical address: 0x109014.
So workaround that by forcing TLB invalidation during page swap.

Add SOC definition for MK22F12 series, larger LQFP-144 K22 series
parts that feature additional peripheral instances.
Additionally, these parts differ from the standard MK22 in the following
ways:
- SYSMPU peripheral is present, so an MPU definition is required
- No external oscillator divider is present
This commit also updates the NXP HAL to include pin control files for
these SOCs.

Supporting Stop1 mode while BLE RF is enabled requires some specific
adaptation and usage of STM32WBA Cube BLE controller scm API.
scm (Secure clock manager) is in charge of switching clock depending
on RF status and should be informed of PM stop modes scheduling.

STM32WBA controller uses a PKA driver to perform cyphering operations
on keys. Since PKA hardware block requires RNG clock to be enabled, a
synchronization with zephyr RNG driver is needed.
Use RNG enable status to check if RNG could be switched off or needs to
be switched on.
Similarly in entropy driver, don't cut RNG clock if PKA is enabled.

This follows the idea to remove any z_ prefix. Since MMU has
a large number of these, separate out these changes into one
commit to ease review effort.
Since these are no longer have z_, these need proper doxygen
doc. So add them too.

Simply to provide some consistencies on file naming under

These are all internally used files and are not public.

This patch enables DSP clock gating for ACE platforms. By default, clock
gating is blocked by the firmware in the hardware configuration. If
CONFIG_ADSP_IDLE_CLOCK_GATING is enabled, this prevent is not active and
clock can be gated when core is in idle state. WIth this option disabled
clock gating will only be enabled in hardware during power gating.

The instruction cache in the STM32F7 and H7 was enabled regardless
of the value assigned via Kconfig to the CONFIG_ICACHE parameter.
This commit adds the missing conditional checks; note that this does
not affect the compiled behavior unless CONFIG_ICACHE is explicitly
disabled by the user.
Remove a redundant low-level check on DCache being already enabled,
since it is also performed inside the SCB_EnableDCache function.
