Ard Biesheuvel 95731b8ee6 ARM: 9059/1: cache-v7: get rid of mini-stack ... Now that we have reduced the number of registers that we need to preserve when calling v7_invalidate_l1 from the boot code, we can use scratch registers to preserve the remaining ones, and get rid of the mini stack entirely. This works around any issues regarding cache behavior in relation to the uncached accesses to this memory, which is hard to get right in the general case (i.e., both bare metal and under virtualization) While at it, switch v7_invalidate_l1 to using ip as a scratch register instead of r4. This makes the function AAPCS compliant, and removes the need to stash r4 in ip across the call.
