Subject: [PATCH 0/3] Detect UDIV/SDIV support from ISAR0
Date: Tue, 12 Mar 2013 18:31:58 -0700 [thread overview]
Message-ID: <1363138321-27849-1-git-send-email-sboyd@codeaurora.org> (raw)
While attempting to upstream a patch to add the IDIV hwcap for
Krait processors, Will suggested we move the code to read the
ISAR0 register. This patchset does that and also works around
the early Krait CPU designs that don't follow the latest ARM ARM
for the ISAR0 register.
Stephen Boyd (3):
ARM: Clear IDIVT hwcap if CONFIG_ARM_THUMB=n
ARM: Detect support for SDIV/UDIV from ISAR0 register
ARM: Work around faulty ISAR0 register in some Krait CPUs
