* Add README, improve documentation for `esp-hal-procmacros`
* Improve documentation for `esp-hal-smartled`
* Use esp-rs logo for all packages' documentation
The ROM code _data_ section is loaded into the middle of the DRAM
address space, unlike the other chips where it is loaded at the end.
Therefore subtracting the previously "reserved" section from heap end
could actually corrupt the ROM data section.
For the ESP32, the DRAM block has been split into two individual
segments, with some reserved segments in the middle (addresses taken
from esp-idf). At the moment we don't use the second segment at all in
esp-hal, but we could utilize it in esp-wifi for placing the internal
allocator for example.
* esp32 & esp32s2 sharing scripts
* add wokwi files
* Add fixup section for esp32s2, fix ordering of sectino includes
* Remove debug asm file
* Use shared linker scripts for s3 with fixups
* Add external.x sections back
* Move ld scripts into esp-hal-common
* esp32c3 unified linker scripts
- rework original c3 script to use the xtensa named sections
(e.g, _SECTIONNAME_start)
- Add fixups in esp32c3 specific linker
- Remove useless text section start and end (not required when using any
form of bootloader)
* Add RTC alias'. Move some shared fixups to a file
* comment and cleanup
* unify c2 linker script
* unify c6 linker script
* remove debug configs
* use new esp-riscv-rt
* fmt
* align db symbol names
* fix s3 db
* Add additional `cfg` gates to re-exports in `esp-hal-common`
This leaves only `clock`, `delay`, `peripheral`, `prelude`, `rom`, and `soc` *not* behind `cfg`s
* Simplify the prelude, update its `cfg`s, and re-export some missing traits
* Update various dependencies
* Extract the `esp-hal-smartled` package
This (finally) eliminates the `esp_hal_common::utils` module!
* Remove all references to the old `smartled` feature from CI
* RISCV: Separate PLIC and non-PLIC
* De-duplicate code
* Write 0 to INTR_MAP again to disable peripheral interrupts
* Limit visibility of `get_assigned_cpu_interrupt`
* Move some linker scripts into `esp-hal-common` and update the build script
* Move `EspDefaultHandler` and `DefaultHandler` definitions into `esp-hal-common`
* Re-export everything from `esp-hal-common`
* Add a couple cfg symbols, cleanup/organize some exports/modules
