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
