d709631393 secure boot: Add boot check for SBV2 "check app signature on update"
As this mode uses the public keys attached to the existing app's signatures to
verify the next app, checking that a signature block is found on boot prevents
the possibility of deploying a non-updatable device from the factory.

37423083bb spi_flash: add config option to override flash size in bootloader header
Sometimes the flash size read from bootloader is not correct. This may
forbid SPI Flash driver from reading the the area larger than the size
in bootloader header.

When the new config option is enabled, the latest configured
ESPTOOLPY_FLAHSIZE in the app header will be used to override the value
read from bootloader header.

d40c69375c bootloader: Add fault injection resistance to Secure Boot bootloader verification
Goal is that multiple faults would be required to bypass a boot-time signature check.

- Also strengthens some address range checks for safe app memory addresses
- Change pre-enable logic to also check the bootloader signature before enabling SBV2 on ESP32

Add some additional checks for invalid sections:

- Sections only partially in DRAM or IRAM are invalid
- If a section is in D/IRAM, allow the possibility only some is in D/IRAM
- Only pass sections that are entirely in the same type of RTC memory region

43393cf4d1 bootloader: Support for skipping validation upon wake from deep sleep
This saves time when waking up from deep sleep, but potentially decreases
the security of the system.  If the application able to modify itself
(especially areas that are loaded into RAM) in flash while running
without crashing or is modifies the cached bits of information about
what was last booted from the bootloader, this could cause security
issues if the user does a "deep sleep reset" since the full validation
is skipped.

d77c74770a bugfix(flash): add flash config in app startup
We fixed some flash bugs in bootloader, but for the users used the old
vrsion bootloader, they can not fix these bugs via OTA, the solution is
add these updates in app startup.

These updates include:
1. SPI flash gpio matrix and drive strength configuration
2. SPI flash clock configuration
3. SPI flash read dummy configuration
4. SPI flash cs timing configuration
5. Update flash id of g_rom_flashchip

62b0d51c02 Enable secure boot only after encrypting flash
This prevents a device from being bricked in case when both secure boot & flash encryption are enabled and encryption gets interrupted during first boot. After interruption, all partitions on the device need to be reflashed (including the bootloader).

List of changes:
* Secure boot key generation and bootloader digest generation logic, implemented inside function esp_secure_boot_permanently_enable(), has been pulled out into new API esp_secure_boot_generate_digest(). The enabling of R/W protection of secure boot key on EFUSE still happens inside esp_secure_boot_permanently_enable()
* Now esp_secure_boot_permanently_enable() is called only after flash encryption process completes
* esp_secure_boot_generate_digest() is called before flash encryption process starts

app_version is filed from PROJECT_VER variable (if set in custom make file) or PROJECT_PATH/version.txt or git repo (git describe).

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.)
