The function tboot_wait_for_aps is not called in atomic context.
Thus mdelay can be replaced with usleep_range, to reduce busy wait.
And how did you establish that it's not called in atomic context?

It is reported by a static analysis tool written by myself.
This tool finds that mdelay in tboot_wait_for_aps is not called by
holding a spinlock or in an interrupt handler, thus mdelay can be replaced.
