6091021e83 unity: separate common and IDF specific functionality
New unity component can be used for testing other applications.
Upstream version of Unity is included as a submodule.
Utilities specific to ESP-IDF unit tests (partitions, leak checking
setup/teardown functions, etc) are kept only in unit-test-app.
Kconfig options are added to allow disabling certain Unity features.

f9f2937694 spi_flash: raise priority of the task performing spi_flash operation
The fix is for the situation when cache disabling mechanism causes
a deadlock with user tasks. Situation is as follows:

1. spi_flash operation is started from low-priority task on CPU0
2. It uses IPC to wake up high-priority IPC1 task on CPU1, preventing
   all other tasks on CPU1 from running. This is needed to safely
   disable the cache.
3. While the task which started spi_flash operation is waiting for IPC1
   task to acknowledge that CPU1 is not using cache anymore, it is
   preempted by a higher priority application task ("app0").
4. Task app0 busy-waits for some operation on CPU1 to complete. But
   since application tasks are blocked out by IPC1 task, this never
   happens. Since app0 is busy-waiting, the task doing spi flash
   operation never runs.

The more or less logical soltion to the problem would be to also do
cache disabling on CPU0 and the SPI flash operation itself from IPC0
task. However IPC0 task stack would need to be increased to allow doing
SPI flash operation (and IPC1 stack as well). This would waste some
memory. An alternative approach adopted in this fix is to call FreeRTOS
functions to temporary increase the priority of SPI flash operation task
to the same level as the IPC task.

92436021ab spi_flash: fix race condition in s_flash_op_complete access
Flash operation complete flag was cleared by the core initiating flash
operation. If the other core was running an ISR, then IPC task could
be late to enter the loop to check s_flash_op_complete by the time next
flash operation started. If the flag is cleared on the CPU waiting on
this flag, then the race condition can not happen.

e76c187efb spi_flash: protect esp_intr_noniram_{disable,enable} in 1-core config
MR !441 (7c155ab) has fixed issue with esp_intr_noniram_{disable,enable}
calls not being properly protected by spi_flash_op_{lock,unlock}.
Unit test was added, but the unit test environment tests only dual-core
config. Similar issue was present in the code path for the single-core
config, where esp_intr_noniram_{disable,enable} calls were unprotected.

This change fixes the protection issue and updates the unit test to
run properly in single core config as well.

The issue with running unit tests for single core config will be
addressed in a separate MR.

36ccdee6ec spi_flash: Flush flash cache if flash_mmap()ing a written-to page
Without this, it's possible for stale information to be read from
cache via mmap, even if the MMU table entry had been invalidated
prior to writing flash (if  the same MMU table entry was re-used after
writing flash.)

7c155ab647 Merge branch 'bugfix/flash_op_unpinned_task' into 'master'
fixes for issues observed when using spi_flash

This MR fixes three unrelated issues:

- Race condition in spi_flash_enable_interrupts_caches_and_other_cpu
  when operations on unpinned tasks are performed.
  The issue is reported in https://github.com/espressif/esp-idf/pull/258

- esp_intr_noniram_disable doesn’t disable interrupts when compiled in
  release mode. This issue manifested itself with an illegal instruction
  exception when task WDT ISR was called at the time when flash was
  disabled.
  Fixes https://github.com/espressif/esp-idf/issues/263.

- Tick hooks on CPU1 were not called if CPU0 scheduler was disabled for
  significant amount of time (which could happen when doing flash erase).
  The issue manifested itself as “INT WDT timeout on core 1” error.
  Fixes https://github.com/espressif/esp-idf/issues/219.

4676d159ad spi_flash: fix race condition when doing operations in unpinned tasks
spi_flash_enable_interrupts_caches_and_other_cpu function used to enable
non-IRAM interrupts after giving up flash operation lock, which would
cause problems if another task was waiting on the lock to start a flash
operation. In fact, non-IRAM interrupts should be re-enabled before the
task scheduler is resumed. Otherwise non-pinned task can be moved to the
other CPU due to preemption, causing esp_intr_noniram_enable to be
called on the other CPU, causing an abort to be triggered.

Fixes the issue reported in
https://github.com/espressif/esp-idf/pull/258
