Duplicate code for makefile purposes, how to avoid?

Question

linux

ubrige: 
 make -j5 TARGET=unwired BOARD=$(BOARD)/$(CPU) -f makefiles/Makefile.[email protected]
 ../bootloader/generate-metadata/generate-metadata [email protected].bin 0x0 0x01A00001 1
 srec_cat firmware-metadata.bin -binary [email protected].bin -binary -offset 0x100 -o [email protected]-ota-image.bin -binary
 rm [email protected].hex

ubrige-fb: ubrige-CLEAN
  ../../tools/backdoor-bootloader.py -e -w -v ubrige-firmware.hex

ubrige-f: ubrige-CLEAN
 /Applications/ti/Uniflash/flash_cc1310.sh ubrige-firmware.hex 

ubrige-ota: ubrige
 scp ubrige-ota-image.bin [email protected]:/root/unwired_smarthome

It is easy to see that the name of the target is often repeated there (in this case, ubrige). This is the name of the project. If I create a new project I have to copy these four targets and then replace ubrige with the new project name. It would be a joke with a replacement, but I don’t like that there is a bunch of the same code in the file.
For the first target, I found [email protected], no longer required to replace all project names in commands.
But it does not reduce the amount of code - you still need to copy several targets for each project. In the example above, the contents of ubrige, ubrige-fb, ubrige-f, ubrige-ota will be the same for all projects, only the ubrige name will differ.
How do I get rid of duplicating code that is the same for several targets, but differs in filenames (let the filenames be the same as the target name)?

You can write a macro target generator. Changing parameters can be passed as macro parameters, internally they can be referenced by number. For example like this:

define generate-targets
$(1): 
 make -j5 TARGET=unwired BOARD=$$(BOARD)/$$(CPU) -f makefiles/[email protected]
 ../bootloader/generate-metadata/generate-metadata [email protected] 0x0 0x01A00001 1
 srec_cat firmware-metadata.bin -binary [email protected] -binary -offset 0x100 -o [email protected] -binary
 rm [email protected]

$(1)-fb: $(1)-CLEAN
  ../../tools/backdoor-bootloader.py -e -w -v $(1)-firmware.hex

$(1)-f: $(1)-CLEAN
 /Applications/ti/Uniflash/flash_cc1310.sh $(1)-firmware.hex 

$(1)-ota: $(1)
 scp $(1)-ota-image.bin [email protected]:/root/unwired_smarthome

endef

Inside the macro, you need to escape $ by replacing it with $$.
This macro can be called at the desired location as follows:
The code generated at this location will be equivalent to the code in the question.

Use variables:

PROJECT=ubridge

$(PROJECT)-fb: $(PROJECT)e-CLEAN
  ../../tools/backdoor-bootloader.py -e -w -v $(PROJECT)-firmware.hex

$(PROJECT)-f: $(PROJECT)-CLEAN
 /Applications/ti/Uniflash/flash_cc1310.sh $(PROJECT)-firmware.hex
