Ok, I guess there is not much that anyone can really complain about here.
What about the arch/arm/mach-stmp37xx/stmp37xx_devb.c file? You don't seem
to have a replacement for that machine.

Also, I noticed that the same series that added support for the platform
also added a few device drivers:
 * drivers/rtc/rtc-stmp3xxx.c
 * drivers/spi/spi_stmp.c
 * drivers/watchdog/stmp3xxx_wdt.c

Are these still used by the new code, and shared with the other i.MX23
code, or is there more duplication?

Finally, there are defconfig files:
 * arch/arm/configs/stmp378x_defconfig
 * arch/arm/configs/stmp37xx_defconfig

I would guess that these need to be updated.
