The following patches implement basic support for the ARMv7-M microcontroller architecture. Additionally, stm32f429-discovery board support is added with tested ability to boot uClinux from the embedded Flash memory.
Kamil Lulko (4): ARM: Add ARMv7-M support ARMv7M: Add STM32F4 support stm32f4: Add serial driver stm32f4: Add support for stm32f429-discovery board
