b364f23e17 secure boot: Support secure boot signatures without hardware secure boot
Allows OTA updates to be secured via signature checks, without requiring the overhead or complexity
of a full secure boot implementation.

Uses same signing mechanisms (build system and/or espsecure.py as Secure Boot).

Requires:
* [ ] More testing
* [ ] Documentation

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.

spi_flash/sim: Fix error test_host. Add stub for bootloader_common_get_sha256_of_partition in sim/stubs

fb439e48f5 bootloader: Don't verify Partition Table as part of Secure Boot
Partition Tables are still signed for backwards compatibility, but signature is no longer checked as
part of bootloader.

17dac0d273 spi_flash: Fix error unit tests on host
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

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.

86256b3541 bootloader: Refactoring
Need to make the bootloader modular so that users can redefine its functional part.

- refactoring and moving functions to the bootloader_support component
- Changed function to `void` bootloader_utility_load_image(...);

c69af42b96 esp32: Fix backwards compatibility for pre-v2.1 bootloaders
Older bootloaders don't set RTC_XTAL_FREQ_REG or call rtc_clk_init(),
app needs to pick this up.

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.)

7c7edab328 flash encryption/secure boot: Restructure documentation
Also add steps to disable flash encryption, as some people seem to
accidentally enable it.

Explicitly mark the flash encryption and secure boot as "READ DOCS
FIRST" in menuconfig.

d8aae55eeb Flash encryption: Temporary fix for issue with stale cache reads
Seems doing certain kinds of short reads while flash encryption is
enabled will return stale data. This fixes it, but is probably a
little heavy-handed performance wise.
