- fix the value of SOC_ROM_STACK_START in soc.h
- Update the memory usage of ROM bootloader appendix in bootloader.ld
- Update the soc_memory_regions table to minimize the number of regions
created after the startup stack is added back as a heap.
This fix ensures that https://nvd.nist.gov/vuln/detail/CVE-2020-27209 is not
reported by the ESP-IDF SBOM tool. Please note that, this CVE was anyways not
applicable for ESP32 platform, as the bootloader (user of micro-ecc library)
do not perform signing on the device, its only verification that happens in
secure-boot-v1 case.
Unlike COMPILE_OPTIONS, COMPILE_DEFINITIONS CMake property assumes
values without the -D prefix, such as NAME or NAME=VAL.
Previously, IDF build system was passing COMPILE_DEFINITIONS build
property to CMake COMPILE_OPTIONS property, so -D prefix was not
a problem.
Now that COMPILE_DEFINITIONS CMake property is used, -D prefix has
to be removed.
(Note that this doesn't affect 'target_compile_definitions' function,
which strips -D prefix before adding the definition to the property.)
The following two functions in bootloader_support are private now:
* esp_secure_boot_verify_sbv2_signature_block()
* esp_secure_boot_verify_rsa_signature_block()
They have been moved into private header files
inside bootloader_private/
* Removed bootloader_reset_reason.h and
bootloader_common_get_reset_reason() completely.
Alternative in ROM component is available.
* made esp_efuse.h independent of target-specific rom header
Adding prop and lit sections to the ELF will let the debugger and the disassembler
have more info about data bytes present in the middle of the Xtensa
instructions, usually used for padding.
The change fixes thread-local-storage size by removing .srodata section
from it. It initially was included in TLS section by mistake.
The issue was found when stack size increased after building applications
with GCC-11.1 compiler. Stack size became bigger because some new data
appeared in .srodata. See more details here:
