2023-03-28ARM: stm32: add support for STM32MP151Roan van Dijk1-0/+1
This patch adds initial support of STM32MP151 microprocessor (MPU) based on Arm Cortex-A7. New Cortex-A infrastructure (gic, timer,...) are selected if ARCH_MULTI_V7 is defined.

2022-08-18ARM: remove obsolete Makefile.boot infrastructureArnd Bergmann1-4/+0
There are a number of old Makefile.boot files that remain from the multiplatform conversion, and three that are still in use. These provide the "ZRELADDR", "PARAMS_PHYS" and "INITRD_PHYS" values that are platform specific. It turns out that we can generally just derive this from information that is available elsewhere: - ZRELADDR is normally detected at runtime with the CONFIG_AUTO_ZRELADDR flag, but also needed to be passed to for 'make uImage'. In a multiplatform kernel, one always has to pass this as the $(LOADADDR) variable, but in the StrongARM kernels we can derive it from the sum of $(CONFIG_PHYS_OFFSET) and $(TEXT_OFFSET) that are already known. - PARAMS_PHYS and INITRD_PHYS are only used for bootpImage, which in turn is only used for the pre-ATAGS 'param_struct' based boot interface on StrongARM based machines with old boot loaders. They can both be derived from CONFIG_PHYS_OFFSET and a machine specific offset for the initrd, so all of the logic for these can be part of arch/arm/boot/bootp/Makefile.

2020-10-03ARM: stm32: Replace HTTP links with HTTPS onesAlexander A. Klimov1-1/+1
Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

2018-03-05ARM: stm32: prepare stm32 family to welcome armv7 architectureLudovic Barre2-15/+15
This patch prepares the STM32 machine for the integration of Cortex-A based microprocessor (MPU), on top of the existing Cortex-M microcontroller family (MCU). Since both MCUs and MPUs are sharing common hardware blocks we can keep using ARCH_STM32 flag for most of them. If a hardware block is specific to one family we can use either ARM_SINGLE_ARMV7M or ARCH_MULTI_V7 flag.
