This patch-level release includes Quad SPI flash support for the STM32F746 DISCOVERY board along with a block interface to go along with it, that may be used with the STM32F746 boards (they are not included by default in the builds, in order to keep the default build binaries under 128K), along with fixing an issue with the STM32F746 build that was causing bad non-kernel-only binaries to be generated.
