This is certainly an OK fix since we use a row of inline nop at
other places.
However after Russell explained the other nops I didn't understand I located
these in boot/compressed/head.S as this in __start:
.rept 7
__nop
.endr
#ifndef CONFIG_THUMB2_KERNEL
mov r0, r0
#else
And certainly this gets compiled, right?
So does .rept/.endr work better than .rep/.endr, is it simply mis-spelled?
I.e. s/.rep/.rept/g
?
In that case we should explain in the commit that .rep doesn't work
but .rept does.
