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
1. use spi functions in rom
2. remove unnecessary GPIO configurations.
3. remove unnecessary dummy settings.
4. enable dummy out function
5. flash and psram have independent timing setting registers.
6. no need to set 1.9v for LDO in 80Mhz
7. set IO driver ability to 1 by default.
8. no need to use GPIO matrix on esp32s2, IO MUX is recommended
9. enable spi clock mode and IO mode settings
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
When config flash mode as QIO mode, the error that esp_rom_spiflash_wait_idle
and esp_rom_spiflash_config_readmode are undefined happens when compile, so
add these two APIs to fix the error.
!4452 used setting LINK_LIBRARIES and INTERFACE_LINK_LIBRARIES to link
components built under ESP-IDF build system. However, LINK_LIBRARIES does
not produce behavior same as linking PRIVATE. This MR uses the new
signature for target_link_libraries directly instead. This also moves
setting dependencies during component registration rather than after all
components have been processed.
The consequence is that internally, components have to use the new
signature form as well. This does not affect linking the components to
external targets, such as with idf_as_lib example. This only affects
linking additional libraries to ESP-IDF libraries outside component processing (after
idf_build_process), which is not even possible for CMake<v3.13 as
target_link_libraries is not valid for targets not created in current
directory. See https://cmake.org/cmake/help/v3.13/policy/CMP0079.html#policy:CMP0079
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).
* Linker was choosing ROM symbols for these, which use integer soft-float
operations and are much slower.
* _divsf3() moved to IRAM to avoid regressions with any code that does
integer float division in IRAM interrupt handlers (+88 bytes IRAM)
* Thanks to michal for reporting:

When flash work in DIO Mode, in order to ensure the fast read mode of flash
is a fixed value, we merged the mode bits into address part, and the fast
read mode value is 0 (the default value).
Removes the need to know/guess the paths to these libraries. Once we are gcc 8 only, we
can remove -nostdlib and no additional arguments are needed for system libraries.
The catch is: any time IDF overrides a symbol in the toolchain sysroot, we need
an undefined linker marker to make sure this symbol is seen by linker.
