define: lock_bits = (lock->status & LOCK_MASK) >> LOCK_SHIFT; This `lock_bits` is the Bit 29-20 of the lock->status
1. spi_hdl_1:
acquire_end_core():
uint32_t status = lock_status_clear(lock, dev_handle->mask & LOCK_MASK);
Becuase this is the first `spi_hdl_1`, so after this , lock_bits == 0`b0. status == 0
2. spi_hdl_2:
acquire_core:
uint32_t status = lock_status_fetch_set(lock, dev_handle->mask & LOCK_MASK);
Then here status is 0`b0, but lock_bits == 0`b10. Because this is the `spi_hdl_2`
3. spi_hdl_2:
`acquire_core` return true, because status == 0. `spi_bus_lock_acquire_start(spi_hdl_2)` then won't block.
4. spi_hdl_2:
spi_device_polling_end(spi_hdl_2).
5. spi_hdl_1:
acquire_end_core:
status is 0, so it cleas the lock->acquiring_dev
6. spi_hdl_2:
spi_device_polling_end:
assert(handle == get_acquiring_dev(host)); Fail

Wrap the ledc, i2c source files with the new caps in CMakeLists and linker.lf.
This could avoid potential source file not found warning during linking time.
For usb_serial_jtag REPL only, xTaskCreate was passing a pointer to
esp_console_repl_com_t, while esp_console_repl_task was expecting
a pointer to esp_console_repl_universal_t.
The way the two structures are defined, this makes no difference, and
the pointer values are the same. Still, this could potentially break
in the future.
(I am not sure what is the distinction between repl_com (common?) and
repl_universal; it seems that `int uart_channel` could just as well
be part of esp_console_repl_com_t; alternatively, as suggested in the
previous commit, this structure could contain a callback function
pointer, which would allow `esp_console_new_repl_*` functions to
specify how stdin/stdout should be initialized by the REPL task.)
The crash occurred when calling setvbuf(stdin,...) with stdin==NULL.
This happened because esp_console_repl_task started running before
its args->uart_channel was initialized; then esp_console_repl_task
went into the code path 'uart_channel != CONFIG_ESP_CONSOLE_UART_NUM',
and tried to 'fopen("/dev/uart/0");`
Since the UART VFS is not registered when ESP_CONSOLE_USB_SERIAL_JTAG
option is enabled, fopen failed and 'stdin' was NULL.
Fix by moving the initialization of repl task arguments before the
start of the task, same as it is done for the usb_cdcacm case.
The crash started happening after the commit 287ab7566b. I haven’t
verified this, but I guess the reason why it wasn’t happening before
was that xTaskCreate was not correctly yielding to the newly created
higher-priority 'repl' task, therefore the code which was setting
the repl task arguments after xTaskCreate had time to execute.
It should be noted that the 'uart_channel' argument is a bit hacky,
in the first place. The code should be refactored to pass a callback
function to the repl task, and let this callback initialize stdin and
stdout based on the chosen console channel. Then esp_console_repl_task
does not require assumptions about the specific interface used.

essl_spi: fix wrong dummy cycle under quad spi mode ant add a test to verify spi quad mod
Closes IDF-5182 and IDF-5181

There are multiple changes in this commit:
1. Unify the RISC-V and ULP-FSM code paths in esp32ulp_mapgen.py.
It seems that these were originally introduced because `nm` output
for the RISC-V case contained symbol sizes, while for the ULP-FSM
no symbol sizes were reported. This makes sense, because the
ULP-FSM object files are produced from assembly source, symbol
sizes have to be added manually using the .size directive.
In the case of RISC-V, the object files are built from C sources
and the sizes are automatically added by the compiler.
Now 'posix' output format is used for both RISC-V and ULP-FSM.
2. Move BASE_ADDR out of esp32ulp_mapgen.py. This now has to be passed
from CMake, which should make it easier to modify if a new chip
with a different RTC RAM base address is added.
3. Add C++ guards to the generated header file.
4. Switch from optparse to argparse for similarity with other IDF
tools.
5. Add type annotations.
* "dummy loop to force pre-processed linker file generation" seems to
be unnecessary. It looks like the idea was copied from the
dependency of ULP-FSM preprocessed source files on the LD script.
* Can use add_dependencies instead of
set_target_properties(...LINK_DEPENDS...) which is more readable
* Use target_link_options instead of target_link_libraries, which is
supported starting from CMake 3.13. Unlike target_link_libraries,
it doesn't require manually quoting the pats.
This commit gives basic mmu driver framework. Now it is able to maintain
mmu virtual address usage on esp32, esp32s2 and esp32s3. Usage to
external virtual address should rely on mmu functions to know which
address range is available, instead of hardcoded.
This commit also improves psram memory that is added to the heap
allocator. Now it's added to the heap, according to the memory
alignment.
Closes https://github.com/espressif/esp-idf/issues/8295
This commit extends the heap test set by adding a test to check corruption
detection in free memory block.
For each byte of the free block memory, the test changes the value of the byte,
call multi_heap_check(), make sure that the function returns 'corruption detected'
only when comprehensive poisoning is set, restore the good value of the byte, calls
multi_heap_check() again and make sure that it returns 'OK'.
