When flash work in DIO Mode, in order to ensure the fast read mode of flash
is a fixed value, we merged the mode bits into address part, and the fast
read mode value is 0 (the default value).
Routine `spi_flash_cache2phys` sometimes return incorrect value,
resulting in failure in getting currently running ota partition.
This in turn aborts firmware update process.This issue was more
prominent with SPIRAM enabled cases.
Fix ensures proper cache guards during `spi_flash_cache2phys`, and
also for few other similar APIs.
In addition, `esp_ota_get_running_partition` has also been optimized
to save currently running partition for subsequent invocations.

* spi_flash_mmap_pages needs pages array to be in internal memory.
Document and check this.
* Fix a bug that spi_flash_mmap did not allocate pages array in
internal memory.
* Minor style fixes: const-ify pages argument of spi_flash_mmap, add
spaces around operators, mark output arguments with [out].
Closes https://github.com/espressif/esp-idf/issues/2229.
IDF had two defines ESP_PARTITION_TABLE_OFFSET and ESP_PARTITION_TABLE_ADDR. They were the same and equal by 0x8000.
A define ESP_PARTITION_TABLE_ADDR was removed from IDF.
A define ESP_PARTITION_TABLE_OFFSET depends on option CONFIG_PARTITION_TABLE_OFFSET in Kconfig.
Now using only #define ESP_PARTITION_TABLE_OFFSET CONFIG_PARTITION_TABLE_OFFSET
Allows you to move the partition table, it gives more space for the bootloader.
Added a new utility - parttool.py. This utility can search for the offset and/or size of the partitions by name and type/subtype. Use for getting APP_OFFSET and PHY_DATA_OFFSET.
The linker(esp32.bootloader.ld) made changes that allow you to write a custom bootloader code more.

Makes spiffs component runnable on host. Depends on the host library build
of flash emulator. Includes a basic sanity test of
mounting a volume, opening a file, writing to the file, reading the file,
closing the file and unmounting volume.
Makes fatfs component runnable on host. Depends on the host library build
of wear levelling and flash emulator. Includes a basic sanity test of
mounting a volume, opening a file, writing to the file, reading the file,
closing the file and unmounting volume.
Makes the entirety of the wl API runnable on host. Flash emulator
is separated into spi_flash component directory to be reused by
other storage components.
When two CPUs read the area of the DPORT and the area of the APB, the result is corrupted for the CPU that read the APB area.
And another CPU has valid data.
The method of eliminating this error.
Before reading the registers of the DPORT, make a preliminary reading of the APB register.
In this case, the joint access of the two CPUs to the registers of the APB and the DPORT is successful.
