#1335421 — [PATCH 0/3] ARM: stm32: Introduce support for STM32F469

Simple set using the STM32F429 infrastructure as a foundation.
There will be more changes to the DTS files and a requirement for
added hierarchical layering as more differences become apparent.

#1335457 — [PATCH 1/3] ARM: stm32: Supply a DTS file for the STM32F469 Discovery board

It's pretty similar to the STM32F429, but there are some
subtle changes required to boot successfully.

Looks good to me. It's the first use of Kconfig fragments we have on ARM,
but it seems justified.

Series applied to my tree for v4.6.
