[fpc-devel] Public access of FPC features and settings

[Michael Ring]

for this command:

~/fpcupdeluxe-embedded/fpc/bin/aarch64-darwin/fpc -Tembedded -Parm 
-WpDISCOVERYF411VE -ix

it would be good to also get back the controllerunitstr that belongs to 
DISCOVERYF411VE


or, when size does not matter much include the unit already in the more 
generalized call:

~/fpcupdeluxe-embedded/fpc/bin/aarch64-darwin/fpc -Tembedded -Parm -ix

....

<controllertype name="DISCOVERYF411VE" unit="STM32F411XE"/>

<controllertype name="STM32F429VG" unit="STM32F429XX"/>

....
