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
* Don't bother checking the chip revision if it looks like the partition
doesn't really contain an app
* Don't print the "info" level about the revision & min revision unless
we're in the bootloader (otherwise it gets printed at random times
during the OTA process)
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
For example, if a renamed option CONFIG_NEW is a bool with value "n", kconfiglib will not generate a define for it in the Kconfig file. The define (#define CONFIG_NEW 1) will only be generated if the option is "y" or "m".
However the compatibility definition was always generated: #define CONFIG_OLD CONFIG_NEW. This broke the #ifdef checks which depended on the old option names.
Using xxx_periph.h in whole IDF instead of xxx_reg.h, xxx_struct.h, xxx_channel.h ... .
Cleaned up header files from unnecessary headers (releated to soc/... headers).
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
1. separate rom include files and linkscript to esp_rom
2. modefiy "include rom/xxx.h" to "include esp32/rom/xxx.h"
3. Forward compatible
4. update mqtt
Added:
* set a secure version in app/bootloader.
* description anti-rollback to ota part
* emulate the secure_version write and read operations
* efuse_em partition.
* a description about a rollback for native_ota_example.
Closes: TW26335
Added a new structure esp_app_desc_t. It has info about firmware:
version, secure_version, project_name, time/date build and IDF version.
Added the ability to add a custom structure with a description of the firmware.
The esp_app_desc_t is located in fixed place in start of ROM secotor. It is located after structures esp_image_header_t and esp_image_segment_header_t.
app_version is filed from PROJECT_VER variable (if set in custom make file) or PROJECT_PATH/version.txt or git repo (git describe).
Add API to get app_desc from 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
components/spi_flash/partition.c: In function 'load_partitions':
components/spi_flash/partition.c:179:66: error: argument to 'sizeof' in 'strncpy' call is the same expression as the source; did you mean to use the size of the destination? [-Werror=sizeof-pointer-memaccess]
strncpy(item->info.label, (const char*) it->label, sizeof(it->label));

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.
TW14125
Added feature:
- reset firmware to Factory app.(by long pressing of the button)
- boot Test app. (by long pressing of the button)
- Added feature erase data partitions from factory reset.
TW10281
TW10280
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(...);
