An alternative approach was suggested by adamgreig in matrix chat:
A default feature, that when enabled makes the BSPs link rp2040_boot2::BOOT_LOADER for you.
Pros:
- No extra boilerplate in every project, completely invisible to the user.
Cons:
- Being invisible means that if it stops working for whatever reason, it's more painful to fix
- Default features do not spark joy
from rp-hal.
One possible disadvantage (of both approaches):
The build tools necessary to build the bootloader (arm-none-eabi-gcc) may not be easily available everywhere. (Windows?)
In that case, one can easily include a precompiled boot2, instead:
#[link_section = ".boot2"]
#[used]
pub static BOOT2: [u8; 256] = *include_bytes!("boot2.bin");
But if rp2040-boot2-rs
is a dependency of the BSP, one also needs to fork the BSP and remove that dependency.
(Please note that there is already a suggestion to change the boot2 crate so the assembler does not run automatically at build time: rp-rs/rp2040-boot2#2. With that change, my point would be void.)

Nearly there!
