* Note
*************************************************************
* 1. ESP32 chip have 4 SPI slave/master, however, SPI0 is
* used as an SPI master to access Flash and ext-SRAM by
* Cache module. It will support Decryto read for Flash,
* read/write for ext-SRAM. And SPI1 is also used as an
* SPI master for Flash read/write and ext-SRAM read/write.
* It will support Encrypto write for Flash.
* 2. As an SPI master, SPI support Highest clock to 80M,
* however, Flash with 80M Clock should be configured
* for different Flash chips. If you want to use 80M
* clock We should use the SPI that is certified by
* Espressif. However, the certification is not started
* at the time, so please use 40M clock at the moment.
* 3. SPI Flash can use 2 lines or 4 lines mode. If you
* use 2 lines mode, you can save two pad SPIHD and
* SPIWP for gpio. ESP32 support configured SPI pad for
* Flash, the configuration is stored in efuse and flash.
* However, the configurations of pads should be certified
* by Espressif. If you use this function, please use 40M
* clock at the moment.
* 4. ESP32 support to use Common SPI command to configure
* Flash to QIO mode, if you failed to configure with fix
* command. With Common SPI Command, ESP32 can also provide
* a way to use same Common SPI command groups on different
* Flash chips.

Driver for SPI flash read/write/erase operations
In order to perform some flash operations, we need to make sure both CPUs
are not running any code from flash for the duration of the flash operation.
In a single-core setup this is easy: we disable interrupts/scheduler and do
the flash operation. In the dual-core setup this is slightly more complicated.
We need to make sure that the other CPU doesn't run any code from flash.
When SPI flash API is called on CPU A (can be PRO or APP), we start
spi_flash_op_block_func function on CPU B using esp_ipc_call API. This API
wakes up high priority task on CPU B and tells it to execute given function,
in this case spi_flash_op_block_func. This function disables cache on CPU B and
signals that cache is disabled by setting s_flash_op_can_start flag.
Then the task on CPU A disables cache as well, and proceeds to execute flash
operation.
While flash operation is running, interrupts can still run on CPU B.
We assume that all interrupt code is placed into RAM.
Once flash operation is complete, function on CPU A sets another flag,
s_flash_op_complete, to let the task on CPU B know that it can re-enable
cache and release the CPU. Then the function on CPU A re-enables the cache on
CPU A as well and returns control to the calling code.
Additionally, all API functions are protected with a mutex (s_flash_op_mutex).
In a single core environment (CONFIG_FREERTOS_UNICORE enabled), we simply
disable both caches, no inter-CPU communication takes place.
