These definitions have ended up being chip specific. Moving them into
respective soc_memory_layout.c makes the whole picture of memory
regions easier to see, and also makes adding support for new chips
easier.

3. add approximate brownout detector levels for esp32s2
test_mux register doesn't exist in RTCCNTL anymore, remove it from
struct header. Also remove adc_ll_vref_output implementation, which
depends on that register.
1. Clarify THREADPTR calculation in FreeRTOS code, explaining where
the constant 0x10 offset comes from.
2. On the ESP32-S2, .flash.rodata section had different default
alignment (8 bytes instead of 16), which resulted in different offset
of the TLS sections. Unfortunately I haven’t found a way to query
section alignment from C code, or to use a constant value to define
section alignment in the linker script. The linker scripts are
modified to force a fixed 16 byte alignment for .flash.rodata on the
ESP32 and ESP32-S2beta. Note that the base address of .flash.rodata
was already 16 byte aligned, so this has not changed the actual
memory layout of the application.
Full explanation of the calculation below.
Assume we have the TLS template section base address
(tls_section_vma), the address of a TLS variable in the template
(address), and the final relocation value (offset). The linker
calculates:
offset = address - tls_section_vma + align_up(TCB_SIZE, alignment).
At run time, the TLS section gets copied from _thread_local_start
(in .rodata) to task_thread_local_start. Let’s assume that an address
of a variable in the runtime TLS section is runtime_address.
Access to this address will happen by calculating THREADPTR + offset.
So, by a series of substitutions:
THREADPTR + offset = runtime_address THREADPTR = runtime_address - offset
THREADPTR = runtime_address - (address - tls_section_vma + align_up(TCB_SIZE, alignment)) THREADPTR = (runtime_address - address) + tls_section_vma - align_up(TCB_SIZE, alignment)
The difference between runtime_address and address is same as the
difference between task_thread_local_start and _thread_local_start.
And tls_section_vma is the address of .rodata section, i.e.
_rodata_start. So we arrive to
THREADPTR = task_thread_local_start - _thread_local_start + _rodata_start - align_up(TCB_SIZE, alignment).
The idea with TCB_SIZE being added to the THREADPTR when computing
the relocation was to let the OS save TCB pointer in the TREADPTR
register. The location of the run-time TLS section was assumed to be
immediately after the TCB, aligned to whatever the section alignment
was. However in our case the problem is that the run-time TLS section
is stored not next to the TCB, but at the top of the stack. Plus,
even if it was stored next to the TCB, the size of a FreeRTOS TCB is
not equal to 8 bytes (TCB_SIZE hardcoded in the linker). So we have
to calculate THREADPTR in a slightly obscure way, to compensate for
these differences.

The NimBLE host buffers that consume a significant amount of memory are
now allocated dynamically.
The advantage is that, the memory can be reclaimed in cases where BLE
is turned off and not required for the current boot cycle
spin_lock: cleaned-up port files and removed portmux files
components/soc: decoupled compare and set operations from FreeRTOS
soc/spinlock: filled initial implementation of spinlock refactor
It will decouple the spinlocks into separated components with not depencences of freertos
an similar interface was provided focusing the readabillity and maintenance, also
naming to spinlocks were adopted. On FreeRTOS side the legacy portMUX macros
gained a form of wrapper functions that calls the spinlocks component thus
minimizing the impact on RTOS side.
This feature aims to close IDF-967
soc/spinlock: spinlocks passed on unit test, missing test corner cases
components/compare_set: added better function namings plus minor performance optimization on spinlocks
soc/spinlock: code reordering to remove ISC C90 mix error
freertos/portmacro: gor rid of critical sections multiline macros, placed inline functions instead
soc/spinlock: improved spinlock performance from internal RAM
For cases where the spinlock is executed from IRAM, there is no
need to check where the spinlock object is placed on memory,
removing this checks caused a great improvement on performance.
SOMAXCONN is expected to be defined in this header, but for the esp32

Avoid the issue by including the net/if.h header in sys/socket.h so that

this issue is mainly exposed when using larger (4096) client key in TLS mutual auth,
since it uses multiplications > 2048 when mbedtls_mpi_mul_mpi is used in recursion,
which works only if both operands point to different location than result since
mpi_mult_mpi_overlong() called mbedtls_mpi_grow() to reallocate buffers used in previous
pointer arithmetics and thus corrupting it. Fixed by growing the mpi buffer before
calling mpi_mult_mpi_overlong()

For SoftAP provisioning, if we start Wi-Fi connection as soon as the
apply config request is received, it has been observed that the clients
(Phone apps mostly) do not get the response for this as we switch the

Delaying the connection calls helps mitigate the issue.

The upper transport layer is using big endian ordering. The
PreviousAddress field of a Friend Request message should therefore
be converted to native endianess using sys_cpu_to_be16().
If the duration to publish is roughly the same as the period, we might
end up with elapsed == period, which returns 0 and cancel the periodic
publication. Instead 1 should be returned, just like when the elapsed
time is greater than the period.
Previously the FastPeriodDivisor value was introduced to the model
publication struct. Based on the way it was grouped it seems the
intention was to fit it within the same octet as other bit fields,
but it actually makes the octet overflow by one bit. This ends up
creating another u8_t variable which in turn adds 24 bits of padding
after it.
To keep the size of the struct as compact as possible, group the flag
together with the key index, since that only requires 12 bits. Some
care is needed here, since the mesh stack does have special internal
key index values that require more than 12 bits such as
BLE_MESH_KEY_UNUSED and BLE_MESH_KEY_DEV. In this case restricting
ourselves to 12 bits is fine since the value in the model publication
struct follows 1:1 the value received in the Config Model Publication
Set message, and there the parameter is defined to be exactly 12 bits.
For Low Power node and Proxy Server, the two features
depend on BLE_MESH_NODE in Kconfig.in, here in the
stack there is no need to judge if CONFIG_BLE_MESH_NODE
is enabled.
According to Mesh Spec 3.4.5.3, a node shall implement a local
network interface. And here we limit the situation just based
on the spec, and Provisioner directly sending the msg without
passing through the local network interface.
The 16-bit format group addresses will be stored,
but we don't store (or restore) the virtual label UUIDs,
i.e. after a power cycle the 16-bit group addresses
would be meaningless.
Creates macros for determining model message lengths based on opcode,
payload length and MIC size. Also adds macro wrapping
NET_BUF_SIMPLE_DEFINE to serve the most common use case.
Re-encrypts single-segment application messages when the network seqnum
has changed, to avoid encrypting messages with different seqnums in
network and transport. This operation is only required for unsegmented
messages, as segmented messages don't need to use the same seqnum in
network.
Reinstates the special adv data for friend messages to store the app key
index.
Stores friend queue packets unencrypted, removing any out-of-order
issues caused by seqnum allocation. Also moves as much of the metadata
storage as possible into the packet, allowing us to free up some bytes
of net_buf user data for friend packets.

On Xtensa, backtrace can not recover the two most significant bits of
the address, as the window call size is encoded in these bits.
Because of this, __builtin_return_address modifies these MSBs to
match those of the callee, "fixing" the address. An unfortunate side
effect is that the zero return address, which usually terminates the
backtrace, gets converted to 0x40000000. While there is a valid
instruction at this address, its occurrence in the backtrace is
highly unlikely: this is the first instruction of WindowOverflow4
vector, and IDF apps switch VECBASE to an IRAM location very early at
startup.
Even if frame->exccause != PANIC_RSN_CACHEERR, it is possible that
the cache error interrupt status is set. For example, this may happen
due to an invalid cache access in the panic handler itself.
Check cache error interrupt status instead of frame->exccause to
decide whether to do CPU reset or digital reset.
Also remove unnecessary esp_dport_access_int_pause from
esp_cache_err_get_cpuid, since the panic handler already calls
esp_dport_access_int_abort on entry.
* Don't bother checking the chip revision if it looks like the partition
doesn't really contain an app
* Don't print the "info" level about the revision & min revision unless
we're in the bootloader (otherwise it gets printed at random times
during the OTA process)
When node is being reset, the init functions of each sig-defined
models will be invoked again, this will cause memory leak because
some model internal data will be allocated again.
Hence before trying to allocate memory for them, we add some check
to make sure no memory has been allocated previously.
And for client model, when the init functions are invoked again,
we will clear the list items.
Since in b0491307, which has introduced the optimized window spill
procedure, _xt_context_save did not work correctly when called from
_xt_syscall_exc. This was because unlike _xt_lowint1, _xt_syscall_exc
does not save PS and EPC1. The new version of _xt_context_save
modified PS (on purpose) and EPC1 (accidentally, due to window
overflow exceptions), which resulted in a crash upon 'rfi' from the
syscall.
This commit adds restoring of PS and EPC1 in _xt_context_save. It also
slightly reduces the number of instructions used to prepare PS for
window spill.
Unit test for setjmp/longjmp (which were broken by this regression)
is added.
