From 9b1b61cd8e31d9beba871333d7a798b3adb89288 Mon Sep 17 00:00:00 2001 From: Lucas Stach Date: Thu, 15 Oct 2015 12:32:21 +0200 Subject: ARM: OMAP2+: remove custom abort handler for t410 This is not needed anymore. Handling a potentially pending imprecise external abort left behind by the bootloader is now done in a slightly safer way inside the common ARM startup code. With the recent changes to abort handling, this issue got fixed by 57df53808534 ("ARM: OMAP2+: Fix imprecise external abort caused by bogus SRAM init").
