[Ovmsdev] Time for 3.2.006?

[Michael Balzer]

I've been building and releasing using the patch already on ovms.dexters-web.de.

Toolkit -98 works perfectly in dual core mode. The last issue I had that let me suspect it still needs unicore mode was actually the CAN hardware flaw I
reported and fixed later on.

To switch to the fix:

 1. Install toolkit -98 and the newlib binaries from here: https://github.com/espressif/esp-idf/issues/2892#issuecomment-525286663

    Linux <https://dl.espressif.com/dl/xtensa-esp32-elf-linux64-1.22.0-98-g4638c4f-5.2.0-20190827.tar.gz>

    MacOS <https://dl.espressif.com/dl/xtensa-esp32-elf-macos-1.22.0-98-g4638c4f-5.2.0-20190827.tar.gz>
    Windows <https://dl.espressif.com/dl/xtensa-esp32-elf-win32-1.22.0-98-g4638c4f-5.2.0-20190827.tar.gz> (note the Windows toolchain probably still has
    symlinks instead of copies)

    Also, a new set of Newlib <https://dl.espressif.com/dl/newlib-psram-fix-ldstld-14aug.zip> binaries, recompiled with the above toolchain and with some manual
    fixes to some assembly routines.

 2. Install the newlib binaries into lib/esp32-psram, make sure they are used by symlinking or replacing the standard files:

    -rw-r--r-- 1 balzer users   986574 13. Aug 13:01 libsupc++.a

 3. Checkout branches "spiram-fix-test" on both OVMS and esp-idf. (The esp-idf branch has the fix from
    https://github.com/espressif/esp-idf/issues/2892#issuecomment-525697255)
 4. Disable sdkconfig:CONFIG_WIFI_LWIP_ALLOCATION_FROM_SPIRAM_FIRST (meant to work around PSRAM issues in the wifi blob, which has no toolkit 98 build yet)
 5. make clean && make

There will be some warnings about the toolkit version not matching the idf version, these can be safely ignored.

Regards,
Michael
