2020-05-18common: Drop linux/bitops.h from common headerSimon Glass
Move this uncommon header out of the common header. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-05-18Use __ASSEMBLY__ as the assembly macrosSimon Glass
Some places use __ASSEMBLER__ instead which does not work since the Makefile does not define it. Fix them. Signed-off-by: Simon Glass <sjg@chromium.org>

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! This may brick your system. Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com> Acked-by: Patrice Chotard <patrice.chotard@st.com>
2020-02-13stm32mp1: pwr: use the last binding for pwrPatrick Delaunay

2019-08-27stpmic1: program pmic to keep only the debug unit onPatrick Delaunay
Depending on backup register value, we maintain the debug unit powered-on for debugging purpose. Only BUCK1 is required for powering the debug unit, so revert the setting for all the other power lanes, except BUCK3 that has to be always on. Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com>

2018-05-07SPDX: Convert all of our multiple license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have multiple licenses (in these cases, dual license) declared in the SPDX-License-Identifier tag. In this case we change from listing "LICENSE-A LICENSE-B" or "LICENSE-A or LICENSE-B" or "(LICENSE-A OR LICENSE-B)" to "LICENSE-A OR LICENSE-B" as per the Linux Kernel style document. Note that parenthesis are allowed so when they were used before we continue to use them. Reviewed-by: Fabio Estevam <fabio.estevam@nxp.com> Signed-off-by: Tom Rini <trini@konsulko.com>
