The first eight GPIOs 0..7 (bank A) are connected to eight output terminals and LEDs, plus two relays on the first two outputs. These output loads are active-high. The next eight GPIOs 8..15 (bank B) are connected to eight input terminals with four on-board switches connecting them to ground. Inputs devices are therefore expected to bridge terminals to ground, so the mcp23s17 pullups are activated for GPIO bank B.

| d218db3 | Phil Elwell | 29 July 2020, 12:47:55 UTC | ARM: proc-v7: Force misalignment of early stmia In an attempt to prevent the problem of CPUn not starting, explicitly misalign the scratch space used to save registers acros the cache invalidation. Notes: At this stage in the boot process the core is running with its cache disabled. Before enabling the cache its contents must be explicitly invalidated, a process that requires quite a few registers that the caller must preserve. Evidence suggests that something is writing a block of zeroes over that space at a time when all other cores should be idle, possibly some kind of write-combiner, and the misalignment is designed to disrupt any write-coalescing. In truth, I don't understand why this patch works, and when the failure is so random it is hard to be certain that this isn't just rolling the dice again. One interesting test would be to change the "addeq r12, #4"s to "addeq r12, #0"s determine see if the offset itself is significant or just the additional code.
