This patchset adds basic support for STMicroelectronics STM32 series MCUs.
STM32 MCUs are Cortex-M CPU, used in various applications (consumer
electronics, industrial applications, hobbyists...).
Datasheets, user and programming manuals are publicly available on
STMicroelectronics website.
With this series applied, the STM32F419 Discovery can boot succesfully.
Once this series accepted, next steps will be to add DMA support, as USART,
I2C and SPI IPs don't have any FIFO. Then will come the clock driver, as today
the bootloader has to be patched to enable the needed clocks.
Maxime Coquelin (14):
scripts: link-vmlinux: Don't pass page offset to kallsyms if XIP
Kernel
