I have uploaded my patch to:
http://temp.michael-ring.org/fpc-arm-freertos.patch
I have left out the generated Makefiles to keep the patch (kind of)
readable.
I am able to build the target like this:
make -j clean buildbase CROSSINSTALL=1 OS_TARGET=freertos CPU_TARGET=arm
SUBARCH=armv7em CROSSOPT="-CfFPV4_SP_D16 -XParm-embedded-"
or
make -j clean buildbase CROSSINSTALL=1 OS_TARGET=freertos CPU_TARGET=arm
SUBARCH=armv6m CROSSOPT="-CfSOFT -XParm-embedded-"
make -j clean buildbase CROSSINSTALL=1 OS_TARGET=freertos CPU_TARGET=arm
SUBARCH=armv7m CROSSOPT="-CfSOFT -XParm-embedded-"
Fun Fact: I have to include -CfSOFT in CROSSOPT for armv6m/7m or I will
get this error:
/Library/Developer/CommandLineTools/usr/bin/make -C rtl all
/Library/Developer/CommandLineTools/usr/bin/make -C freertos all

Do you have an idea why? I compared to the embedded target but could not
find something obvious....
The freertos bindings are not included yet as I am still testing &
learning and I need your guidance on how to provide the lib/*.o files
for freertos:
I currently build freertos rtl as three different versions with a
hopefully sane base-set of configuration options, the question is where
to put the matching *.o or *.a files, check them in in fpc or provide
build instructions on the Wiki similar to the buildinstructions for
xtensa target??
I have uploaded a zipfile with everything needed to build a freertos
environment:
http://temp.michael-ring.org/FreeRTOS-Bootstrap.zip
The Build also includes prebuilt .o files.
To build yourself you will first have to manually adjust the
buildFreeRTOS.sh script so that it points to a correct arm-none-eabi-gcc.

Florian, can you please have a look at the patches and apply them if
they are OK?
I have committed the patch with some extensions/adaptions. With
current trunk, I can build a hello world following the wiki
instructions with ESP-IDF 4.0.
Regarding the FreeRTOS binding for ARM: can you provide a patch somewhere?
