This patch moves the libgcc Makefile inclusion from the toplevel Makefile to the arch_config.mk files. This is in preparation for the ARM architecture to move away from including libgcc function and only using self-contained U-Boot functions as done in Linux.
why not change the top level Makefile to read: PLATFORM_LIBGCC ?= ...
then any board/arch that doesnt want it can simply do: PLATFORM_LIBGCC = # dont want it
because you need to provide the equivalent functions for standalone application and api and U-Boot ofcourse
so move it to config.mk. this doesnt change the important point: leave PLATFORM_LIBGCC default in the toplevel common files. what i proposed doesnt limit what you want to do with arm in any way.
I think it's better to let it at arch level and force any new arch adding to manage it instead provide a default one
considering most arches want this code, i dont think so. you're proposing we duplicate the same common code in all arches to support one deviating arch -- arm. the defaults should reflect the common state while the deviating ones change the behavior as they like.
This is where I disagree other arch as mips and other will also need to move away from the needs to include libgcc to be really toolchain independant
I do think it's really important for U-Boot be able to have full control to have a functions embedded into.
So stop to have libgcc include by default will really reflect it
