ARM: remove obsolete Makefile.boot infrastructure

2022-08-18T14:44:59Z

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. Signed-off-by: Arnd Bergmann

ARM: stm32: Replace HTTP links with HTTPS ones

2020-10-03T19:38:54Z

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.
