Alex Albino 80d37d936c esp32: Add support for ESP32-D2WD with 2MiB internal flash. 
This patch adds a partitions file for the D2WD and a new board GENERIC_D2WD
which runs on these chip variants.

Resolves issue #4986.

Damien George e9af6f5f88 esp32/boards/TINYPICO: Switch to use QIO and 80MHz for SPI interface. 2019-09-10 11:10:19 +10:00
Jim Mussared 8db517f26d esp32: Add per-board configs, following other ports. 
Replaces the `SDKCONFIG` makefile variable with `BOARD`.  Defaults to
BOARD=GENERIC.  spiram can be enabled with `BOARD=GENERIC_SPIRAM`

Add example definition for TINYPICO, currently identical to GENERIC_SPIRAM
but with custom board/SoC names for the uPy banner.

Damien George 69cb24a21d esp32/boards/sdkconfig: Disable WDT check of idle task on CPU1. 
With dual-core enabled it's possible that the uPy task has full utilisation
of CPU1.  Fixes issue #4673.

Damien George 92149c8a79 esp32/boards: Enable dual core support by default. 
Single core is still supported, just by adding CONFIG_FREERTOS_UNICORE=y to
a custom sdkconfig file.

Damien George c33f538066 esp32/modmachine: Add support for changing the CPU frequency. 2019-02-07 22:51:55 +11:00
Damien George 6a95e74387 esp32: Use SPIRAM in mem-map mode so all of it can be used for uPy heap. 
Also enable CONFIG_SPIRAM_IGNORE_NOTFOUND to allow boards with faulty or
missing SPIRAM to still boot.

Damien George f431795caf esp32/boards: Use auto xtal freq config instead of default 40MHz. 
Auto-detection of the crystal frequency is convenient and allows for a
single binary for many different boards.  But it can be unreliable in
certain situations so in production, for a given board, it's recommended to
configure the correct fixed frequency.

Damien George 3d49b157b8 esp32: Update to latest ESP IDF using sdkconfig and new ldgen procedure. 
Configuration for the build is now specified using sdkconfig rather than
sdkconfig.h, which allows for much easier configuration with defaults from
the ESP IDF automatically applied.  sdkconfig.h is generated using the new
ESP IDF kconfig_new tool written in Python.  Custom configuration for a
particular ESP32 board can be specified via the make variable SDKCONFIG.

The esp32.common.ld file is also now generated using the standard ESP IDF
ldgen.py tool.
