Subject: [PATCH] arm: update ARM_ERRATA_430973 Kconfig
Date: Mon, 18 Feb 2013 18:15:04 +0100 [thread overview]
Message-ID: <1361207704-11609-1-git-send-email-tim.niemeyer@corscience.de> (raw)
We had strange problems with some illegal instructions and segmentation
faults. It turns out that the OMAP3503D (Cortex A8 r1p3) suffers from
erratum 430973.

This option enables the workaround for the 430973 Cortex-A8

+ (r1p*) erratum. If a code sequence containing an ARM/Thumb
interworking branch is replaced with another code sequence at the
same virtual address, whether due to self-modifying code or virtual
to physical address re-mapping, Cortex-A8 does not recover from the
