2020-03-24arm: stm32mp: bsec: add permanent lock support in bsec driverPatrick Delaunay
Add BSEC lock access (read / write) at 0xC0000000 offset of misc driver. The write access only available for Trusted boot mode, based on new SMC STM32_SMC_WRLOCK_OTP. With the fuse command, the permanent lock status is accessed with 0x10000000 offset (0xC0000000 - 0x8000000 for OTP sense/program divided by u32 size), for example: Read lock status of fuse 57 (0x39) STM32MP> fuse sense 0 0x10000039 1 Sensing bank 0: Word 0x10000039: 00000000 Set permanent lock of fuse 57 (0x39) STM32MP> fuse prog 0 0x10000039 1 Sensing bank 0: Word 0x10000039: 00000000 WARNING: the OTP lock is updated only after reboot WARING: Programming lock or fuses is an irreversible operation!

2020-02-05dm: core: Create a new header file for 'compat' featuresSimon Glass
At present dm/device.h includes the linux-compatible features. This requires including linux/compat.h which in turn includes a lot of headers. One of these is malloc.h which we thus end up including in every file in U-Boot. Apart from the inefficiency of this, it is problematic for sandbox which needs to use the system malloc() in some files. Move the compatibility features into a separate header file. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-02-05dm: core: Require users of devres to include the headerSimon Glass
At present devres.h is included in all files that include dm.h but few make use of it. Also this pulls in linux/compat which adds several more headers. Drop the automatic inclusion and require files to include devres themselves. This provides a good indication of which files use devres.
