ESP32 V1 and V2 - protection bits.
ESP32xx V2: revoke bits, protection bits
- refactor efuse component
- adds some APIs for esp32 chips as well as for esp32xx chips
Summary of changes:
- bootloader_clock split into *_clock_init and *_clock_loader.
Only esp_clk_apb_freq is in *_clock_loader.
- bootloader_common moved out of loader; functions needed in loader
(or, referenced from bootloader_utility) were moved into
bootloader_common_loader.c.
- assert and abort moved into bootloader_panic, made part of the
loader
- rtc_clk and rtc_time made part of loader
flash_enctryption: enabled flash encryption example on esp32s2
bootloader: raise WDT overflow value providing sufficient interval to encrypt app partition
flash_ encrypt: Fixed the TODOs on flash encryption key generation for esp32s2
flash_encryption: added secure boot features to flash enctryption for esp32s2
bootloader: leave only esp32s2 compatible potentially insecure options on menuconfig.
flash_encryption: removed secure boot version 1 from esp32s2 encryption code
flash_encryption: added CONFIG_SECURE_FLASH_REQUIRE_ALREADY_ENABLED option for esp32s2
flash_encryption: fixed the count of left plaintext flash
flash_encryption: disable dcache and icache download when using encryption in release mode
flash_encryption: add cache potentally insecure options for s2 chips
flash_encryption: fixed bug which bricked some chips in relase mode
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
Do not include bootloader in flash target when secure boot is enabled.
Emit signing warning on all cases where signed apps are enabled (secure
boot and signed images)
Follow convention of capital letters for SECURE_BOOT_SIGNING_KEY variable, since it is
relevant to other components, not just bootloader.
Pass signing key and verification key via config, not requiring
bootloader to know parent app dir.
Misc. variables name corrections
Bootloader build requires verification key to be embedded in the binary.
Under specific configs, this key is generated during build time from the
signing key. Move the key generation to after the component
registration, since non scriptable commands are used in the process
(during early expansion)
This MR improves existing flash encryption document to provide simplified steps
Adds two new modes for user: Development & Release
Adds a simple example
Supports encrypted write through make command

!4452 and !4897 made some ill-advised corrections to dependency info;
revert those in this MR. Handling pre-built binaries as imported
libraries is retained, however.
This MR removes the common dependency from every IDF components to the SOC component.
Currently, in the ``idf_functions.cmake`` script, we include the header path of SOC component by default for all components.
But for better code organization (or maybe also benifits to the compiling speed), we may remove the dependency to SOC components for most components except the driver and kernel related components.
In CMAKE, we have two kinds of header visibilities (set by include path visibility):
(Assume component A --(depends on)--> B, B is the current component)
1. public (``COMPONENT_ADD_INCLUDEDIRS``): means this path is visible to other depending components (A) (visible to A and B)
2. private (``COMPONENT_PRIV_INCLUDEDIRS``): means this path is only visible to source files inside the component (visible to B only)
and we have two kinds of depending ways:
(Assume component A --(depends on)--> B --(depends on)--> C, B is the current component)
1. public (```COMPONENT_REQUIRES```): means B can access to public include path of C. All other components rely on you (A) will also be available for the public headers. (visible to A, B)
2. private (``COMPONENT_PRIV_REQUIRES``): means B can access to public include path of C, but don't propagate this relation to other components (A). (visible to B)
1. remove the common requirement in ``idf_functions.cmake``, this makes the SOC components invisible to all other components by default.
2. if a component (for example, DRIVER) really needs the dependency to SOC, add a private dependency to SOC for it.
3. some other components that don't really depends on the SOC may still meet some errors saying "can't find header soc/...", this is because it's depended component (DRIVER) incorrectly include the header of SOC in its public headers. Moving all this kind of #include into source files, or private headers
4. Fix the include requirements for some file which miss sufficient #include directives. (Previously they include some headers by the long long long header include link)
This is a breaking change. Previous code may depends on the long include chain.
You may need to include the following headers for some files after this commit:
- soc/soc.h
- soc/soc_memory_layout.h
- driver/gpio.h
- esp_sleep.h
The major broken include chain includes:
1. esp_system.h no longer includes esp_sleep.h. The latter includes driver/gpio.h and driver/touch_pad.h.
2. ets_sys.h no longer includes soc/soc.h
3. freertos/portmacro.h no longer includes soc/soc_memory_layout.h
some peripheral headers no longer includes their hw related headers, e.g. rom/gpio.h no longer includes soc/gpio_pins.h and soc/gpio_reg.h
BREAKING CHANGE
* Philosophical: "explicit is better than implicit".
* Practical: Allows useful errors if invalid directories given in components as the defaults aren't
always used. Also trims the -I path from a number of components that have no actual include
directory.
* Simplifies knowing which components will be header-only and which won't
