Revert "ARM: Make low-level printk work"
This reverts commit 63d454ab530bb3ab5412aabd6be6ee8cd340888e. Per Andy's request, Andy's rational: "I don't think that makes any sense any more and should be removed, unless there's some case on Android side that really needs it. Vanilla has better DEBUG_LL support now since 2005 when that patch was introduced and the Android kernels will inherit it. I've reverted it in my tree since we commonly need DEBUG_LL on (but we don't need printascii garbling all our logging as if there was an echo in there). ...[It] basically forces all printk output down printascii() which is not what we want. earlyprintk=1 earlycon=ttyO2,115200n8 On your commandline will get you going [without this]" Change-Id: I1da455354b4a8ff3bc9c5f66f5a174b13e179ae6 Signed-off-by: John Stultz <john.stultz@linaro.org>
