In commit 7a908832ac ("spi: imx: add fallback feature") the last
user of the struct spi_imx_devtype_data::disable_dma callback was
removed. However the disable_dma member of struct spi_imx_devtype_data
and the callback itself was not removed.
Remove struct spi_imx_devtype_data::disable_dma and mx51_disable_dma()
as they are unused.

When a console stack dump is initiated with CONFIG_GCOV_PROFILE_ALL

This happens when the compiled code for show_stack() has a single word
on the stack, and doesn't use a tail call to show_stack_log_lvl().
(CONFIG_GCOV_PROFILE_ALL=y is the only known case of this.) Then the
__unwind_start() skip logic hits an off-by-one bug and fails to unwind
all the way to the intended starting frame.
Fix it by reverting the following commit:
f1d9a2abff ("x86/unwind/orc: Don't skip the first frame for inactive tasks")
The original justification for that commit no longer exists. That
original issue was later fixed in a different way, with the following
commit:

Variables hw_ctrl_s1 and sw_ctrl_s1 are not being initialized and
potentially can contain any garbage value. Currently there is an if
statement that sets one or the other of these variables, followed
by an if statement that checks if any of these variables have been
set to a non-zero value. In the case where they may contain
uninitialized non-zero values, the latter if statement may be
taken as true when it was not expected to.
Fix this by ensuring hw_ctrl_s1 and sw_ctrl_s1 are initialized.

Dynamic loading of external libraries should not be done if the firmware
was booted from IMR since in that case the libraries will be restored along
with the basefw.
The booted_from_imr flag is introduced and set to true if the IMR boot was
successful and to false if cold booting is executed.
The reason for the new flag is that guessing from existing flags, used to
decide if we should try booting from IMR or not is not going to be robust
as the IMR boot itself can fail and in that case a full, cold boot is
executed.

With IPC4 each DSP loadable binary is a library, which contains
ext_manifest section and loadable modules.
The basefw is no exception, it is always library 0 and it can contain
several modules, depending on the firmware build.
The current code assumes only one binary, which is the basefw and has no
concept of libraries.
This patch introduces the library+modules abstraction and represents the
basefw as library for the IPC4 loader codebase.
The basefw loading and handling is not changing, it is still done by the
generic code, but it's information is cloned under the library
representation.
The libraries are managed via XArray to offload the list and ID management.

qmi_elem_info") allows QMI message encoding/decoding rules to be
const, so do that for IPA.

The stm32_rng_read() function samples TRNG by 4 bytes until at
least 5 bytes are free in the input buffer. The last four bytes
are never read. For example, 60 bytes are returned in case the
input buffer size is 64 bytes.
Read until at least 4 bytes are free in the input buffer. Fill
the buffer entirely in case the buffer size is divisible by 4.

The stm32_rng_read() function uses `retval` variable as a counter of
generated random bytes. However, the same variable is used to store
a result of the polling function in case the driver is waiting until
the TRNG is ready. The TRNG generates random numbers by 16B. One
loop read 4B. So, the function calls the polling every 16B, i.e.
every 4th loop. The `retval` counter is reset on poll call and only
number of bytes read after the last poll call is returned to the
caller. The remaining sampled random bytes (for example 48 out of
64 in case 64 bytes are read) are not used.
Use different variable to store the polling function result and
do not overwrite `retval` counter.

Add missing statesize to hash templates.
This is mandatory otherwise no algorithms can be registered as the core
requires statesize to be set.

When a test mode invokes multiple tests (e.g., mode 0 invokes modes
1 through 199, and mode 3 tests three block cipher modes with des),
don't keep accumulating the return values with ret += tcrypt_test(),
which results in a bogus value if more than one report a nonzero
value (e.g., two reporting -2 (-ENOENT) end up reporting -4 (-EINTR)).
Instead, keep track of the minimum return value reported by any
subtest.

Adding RNG NPCM8XX support to NPCM RNG driver.
RNG NPCM8XX uses a different clock prescaler.
As part of adding NPCM8XX support:
- Add NPCM8XX specific compatible string.
- Add data to handle architecture specific clock prescaler.
