Plenty of dependency adjustments, printf format specificier updates,
FreeRTOS type and macro name modernisation, not to mention API changes.
Still plenty of legacy/deprecated drivers in use which will need updating.
The following features have been removed due to no longer being available
from the IDF:
- ADC hall effect sensor reading
- Configuration of SD SPI host via sdmmc module (now must be done first
via the spimaster module)
- FAT partition selection on external SD cards; only the first FAT
partition is supported by the IDF now
On the other hand, the eth module now supports the following new chipsets:
- KSZ8001
- KSZ8021
- KSZ8031
- KSZ8051
- KSZ8061
- KSZ8091
- Possibly additional models in the LAN87xx series (the IDF docs aren't
clear on precisely which models are handled)
Further, the sdmmc module is now available on the ESP32-S3 as well.
Search-and-replace considered harmful. I completely missed the need to
explicitly declare "fast" tag functions (__xyz) in the mask field to
LROT_BEGIN()/LROT_END() when I brought over the 5.1+5.3 support.
Without those flags set properly, the LVM doesn't even bother going
looking for those methods, which in this case led to garbage collection
not calling the __gc functions, among other horrible things.
Mea culpa.
Changes have been kept to a minimum, but a serious chunk of work was
needed to move from 8266isms to IDFisms.
Some things got refactored into components/lua/common, in particular
the LFS location awareness.
As part of this work I also evicted our partition table manipulation
code, as with the current IDF it kept breaking checksums and rendering
things unbootable, which is the opposite of helpful (which was the
original intent behind it).
The uart module got relocated from base_nodemcu to the modules component
properly, after I worked out how to force its inclusion using Kconfig alone.
