The current implementation uses the `r12` register as temporary storage
for r4. However, `r12` is a call-clobbered register, meaning its
contents are not preserved across function calls. This becomes
problematic when we later call the `zeromem` function, as any
information stored in `r12` will be lost. To address this issue, we
should avoid using `r12` to store boot parameters.
