Hello, This patch is needed by the sensorhub driver which uses STM32F4xx and Jonathan suggested to factor out these sources (mentioned in: [RFC/PATCH 2/6] misc: sensorhub: Add sensorhub). I feel a bit ashamed because I know a bit STM32F4 controllers but I did not realize that it is generic ST protocol. It helped us a lot because this code really needed some refactoring. So this patch contains SPI protocol used in the STM32 bootloader and is based on AN4286. Generally it can be used to implement handling of other interfaces like UART or I2C because the flow is quite similar and maybe adding proper hw access callbacks will do all work. It supports: - get info frame - get version - firmware write (write, read, write address, erase) >From v2: some typos fixes kfree to devm_kfree in error handling ... generally things advised by Antonio Borneo for v2 TODO (I will not have had time to touch it for few weeks): erase command with sector mode command checking and disabling unimplemented ones Also some Antonio opinion is needed if we are able (or want) to use the same stm32_core layer for this.
