This patch results in boot stalls with several qemu aspeed emulations (quanta-q71l-bmc, palmetto-bmc, witherspoon-bmc, ast2500-evb, romulus-bmc, g220a-bmc). Reverting this patch together with "clocksource/drivers/fttmr010: Clear also overflow bit on AST2600" fixes the problem. Bisect log is attached.
