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.)
For config-only components, component.mk should now contain "COMPONENT_CONFIG_ONLY := 1"
Also refactored some of the generation of linker paths, library list. This required cleaning up the way the bootloader
project works, it's now mostly independent from the parent.
Now the tests do not pass
Before we had incorrect code of the error code checking
in build_examples.sh for that case and did nothing in test_build_system.sh.
The CI uses the mirror-submodule-update.sh for non-permanent reassignment
of 3rdparty sub-modules to local mirrors (only for 'non-master' branches).
List of the mirrors in mirror-list.txt
You can use the script locally to speed up data retrieval on network problems
check_submodule_sync job uses 'GIT_STRATEGY: clone' to check the availability of public sources
Implements support for system level traces compatible with SEGGER
SystemView tool on top of ESP32 application tracing module.
That kind of traces can help to analyse program's behaviour.
SystemView can show timeline of tasks/ISRs execution, context switches,
statistics related to the CPUs' load distribution etc.
Also this commit adds useful feature to ESP32 application tracing module:
- Trace data buffering is implemented to handle temporary peaks of events load
Add new "make size_components" and "make size_files" targets for analysing makeup of the ELF file.
Plain "make size" output now looks like this:
Total sizes:
DRAM .data size: 11156 bytes
DRAM .bss size: 22304 bytes
Used static DRAM: 33460 bytes ( 294220 available, 10.2% used)
Used static IRAM: 80480 bytes ( 50592 available, 61.4% used)
Flash code: 421463 bytes
Flash rodata: 103824 bytes
Total image size:~ 616923 bytes (.bin may be padded larger)
Run some unit test cases based (poorly) around sodium's test infrastructure.
Increase in unity test task stack is due to signature tests, load a lot of data onto the stack.
CI: auto generate configs for test jobs
Currently CI test jobs are static configured by several pre-generated config files.
This approach have several disadvantages:
1. not flexible to select test cases to run, which is important feature of @bot
2. difficult to update test as we need to pre-generate quite a lot files
3. need to maintain extra config files in IDF
4. not flexible to support new test apps or chips, can't use some new features of test bench
Therefore we'll add assign_test stage between build and test, to generate configs for test jobs.

CI: save download config in CI build jobs:
IDF built app download config may change with some modification.
save the download configs for built APP in build stage.
then we can use the correct download config in test stage.

FATFS fixes and tests
This MR includes a set of fixes related to FATFS, SDMMC, and wear levelling:
- `esp_vfs_fat_spiflash_mount` uses `FM_SFD` flag when creating the partition. The volume layout (given in `VolToPart` variable) was not compatible with SFD mode, so mkfs was failing. This fixes the volume layout to use "autodetect" for both volumes. Merges https://github.com/espressif/esp-idf/pull/559.
- fix `prepend_drive_to_path`function, which didn't prepend drive to path (while consuming 2k of stack space)
- fix stack overflow in vfs_fat_link function which allocated two 4kbyte `FIL` structures on the stack
- fix support for having two FATFS instances (in flash and SD) mounted at the same time
- unit tests written for FATFS on SDMMC are made common between SDMMC and WL implementations; FATFS unit tests on WL will run during CI
- fix inconsistent definition of PATH_MAX and ARG_MAX (TW12207, TW12104, https://github.com/espressif/esp-idf/issues/289)

IDF built app download config may change with some modification.
save the download configs for built APP in build stage.
then we can use the correct download config in test stage.
wear levelling
This MR adds wear levelling component. It presents an interface similar to the interface of spi_flash and esp_partition. Inside, it stores data inside a partition to in a way that reduces worst case number of erase cycles for any given sector.
Also included are APIs similar to the ones provided for SDMMC to mount FAT filesystem on top of the wear levelling partition. A simple example shows how this API can be used.

- Implements application tracing module which allows to send arbitrary
data to host over JTAG. This feature is useful for analyzing
program modules behavior, dumping run-time application data etc.
- Implements printf-like logging functions on top of apptrace module.
This feature is a kind of semihosted printf functionality with lower
overhead and impact on system behaviour as compared to standard printf.
Windows setup improvements
* Tweak Makefile to significantly reduce startup time on Windows (also reduced on other platforms, but less obvious.)
* Revise windows setup installation script to fix various issues, use latest toolchain.
* Tweak Windows config docs

SPI flash operations lock for shorter periods
Based on bug report here:
https://esp32.com/viewtopic.php?f=13&t=1489&p=6816#p6773
Long SPI flash erase (and possibly write/read) cycles block all tasks on both CPUs for an extended period, and can lead to WiFi dissassociation (and general priority inversion.)
This MR inserts preemption breaks into large operations (all erases, writes every 8KB, reads every 16KB).
Overhead of a single spi_flash_guart_start()/spi_flash_guard_end() cycle measured at approx 67us (assuming no preemption.)
