The patch looks good, but I'm not sure I should apply it.
Indeed, not all the stm32 boards have Ethernet interface, and stm32
internal flash size is rather limited (2MB).
Note that your glue layer can be compiled with COMPILE_TEST, so its
build will be covered anyway.
Arnd, do you think we could use Kconfig fragments to enable features
like USB, Ethernet, MTD, etc...?
Maybe we could have a subdirectory in arch/arm/configs where these stm32
specifics fragments could leave?
For example, we could have:
arch/arm/configs/stm32/eth.config
arch/arm/configs/stm32/usb.config
For configuring the Discovery board we would use:
make stm32_defconfig stm32/usb.config
For the Eval board, we cwould use:
make stm32_defconfig eth.config
It would make easy to be able to boot every boards without multiplying
the defconfigs.
Regards,
Maxime
