Similar to stm32f429_disco, this commit adds a configuration for the Cortex-M4 based STM32F469 platform. It requires a few kernel patches, which have already been submitted upstream, as well as a small OpenOCD patch. Besides that, it re-uses most of what has been added for the STM32F429 platform.

Subject: [PATCH] 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.
