b3aff63db4 app_update: fix intermittent failure with firmware updates
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.

117c79eae5 app_update: Add API for getting sha256_of_partition
Added bootloader_common_get_sha256_of_partition() and esp_partition_get_sha256() - get or calculate SHA-256
digest for app and data partitions.
Added bootloader_sha256_hex_to_str() - helps to print SHA-256 digest
Added esp_partition_check_identity() - compares two partitions by SHA-256 digest

Refactoring a function esp_image_load() in bootloader space to esp_image_verify() and
bootloader_load_image(). Old name function esp_image_load is deprecated
and will remove in V4.0 version.

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.

3e0ac4db79 partition_table: Expanding the space under the bootloader
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.

8f80cc733d soc: Change DPORT access
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.

17adb40ca8 bootloader: Calculate SHA256 hash of image on every boot
Makes app image booting more reliable (256-bit rather than 8-bit verification.)

Some measurements, time to boot a 655KB app.bin file and run to app_main() execution.

(All for rev 1 silicon, ie no 340ms spurious WDT delay.)

80MHz QIO mode:
before = 300ms
after = 140ms

40MHz DIO mode:
before = 712ms
after = 577ms

40MHz DIO mode, secure boot enabled
before = 1380ms
after = 934ms

(Secure boot involves two ECC signature verifications (partition table, app) that take approx 300ms each with 80MHz CPU.)

85e76a7cfc spiflash ROM functions: Remove Quad I/O mode enable/disable code from flash ROM functions
Confusion here is that original ROM has two functions:

* SPIReadModeCnfig() - sets mode, calls enable_qio_mode/disable_qio_mode
* SPIMasterReadModeCnfig() - As above, but doesn't set QIO mode in status register

However we never want to use the ROM method to set/clear QIO mode flag, as not all flash chips work this way. Instead we
do it in flash_qio_mode.c in bootloader.

So in both cases (ROM or "patched ROM") we now call SPIMasterReadModeCnfig(), which is now named
esp_rom_spiflash_config_readmode().

cbb71baca9 spi_flash: protect spi_flash_unlock
spi_flash_unlock was missing spi_flash_guard_start, which caused cache
to be enabled during unlock operation, causing hard-to-trace crashes
and cache data corruption.

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.
