Dario Nieuwenhuis	13328c58d3	examples/stm32wb: do not reserve words at start of RAM. They're used to communicate from the app to ST's OTA bootloader. See AN5247. This bootloader is optional, must be flashed by the user, and requires changing the FLASH start address as well, so the current memory regions still require modifications to use it. Therefore there's no point in reserving these words. Thanks @adamgreig for investigating the purpose.	2023-02-20 01:01:01 +01:00

cortex-m-rt 0.7.2 now enforces the stack is 8-byte aligned. Stack is placed
at `ORIGIN(RAM) + LENGTH(RAM)` by default, which wasn't 8-byte-aligned. See https://github.com/rust-embedded/cortex-m/discussions/469

ST trims 8 bytes from start of RAM, and uses the whole 192kb, so let's just
copy that:
