7755015f4f secure boot: Fix enabling secure boot on first bootloader boot
Bootloader would accidentally check its own image for a secure boot signature,
but bootloader is unsigned (protected by secure boot digest).

5eef5e7a5d bootloader: Fallback if OTA data is invalid

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.)

26a3cb93c7 component/soc : move dport access header files to soc
1. move dport access header files to soc
2. reduce dport register write protection. Only protect read operation

f7e8856520 component/esp32 : fix dualcore bug
1. When dual core cpu run access DPORT register, must do protection.
2. If access DPORT register, must use DPORT_REG_READ/DPORT_REG_WRITE and DPORT_XXX register operation macro.

3b583c150f bootloader: disconnect VRTC from SAR input in bootloader_random_disable
Bootloader enables SAR ADC in test mode to get some entropy for the RNG.
The bits which control the ADC test mux were not disabled, which caused
extra ~24uA current to be drawn from VRTC, increasing deep sleep current
consumption. This change disables relevant test mode bits in
bootloader_random_disable.

c48612e516 mbedTLS SHA acceleration: Allow concurrent digest calculation, works with TLS
SHA hardware allows each of SHA1, SHA256, SHA384&SHA512 to calculate digests
concurrently.

Currently incompatible with AES acceleration due to a hardware reset problem.

60f29236f6 Build system: Raise warning level
Default esp-idf builds now show -Wextra warnings (except for a few:
signed/unsigned comparison, unused parameters, old-style C declarations.)

CI building of examples runs with that level raised to -Werror, to catch
those changes going into the main repo.
