In August 2012, Matthew Gretton-Dann checked a change into binutils labelled "Error on obsolete & warn on deprecated registers", apparently as part of ARMv8 support. Apparently, this was supposed to emit the message "Warning: This coprocessor register access is deprecated in ARMv8" when using certain mcr/mrc instructions and building for ARMv8. Unfortunately, the message that is actually emitted appears to be '(null)', which is less helpful in comparison. Even more unfortunately, this is biting us on every single kernel build with a new gas, because arch/arm/boot/compressed/head.S and some other files in that directory are built with -march=all since kernel commit 80cec14a8 "[ARM] Add -march=all to assembly file build in arch/arm/boot/compressed" back in v2.6.28. This patch reverts Russell's nice solution and instead marks the head.S file to be built for armv7-a, which fortunately lets us build all instructions in that file without warnings even on the broken binutils. Without this patch, building anything results in: arch/arm/boot/compressed/head.S: Assembler messages: arch/arm/boot/compressed/head.S:565: Warning: (null) arch/arm/boot/compressed/head.S:676: Warning: (null) arch/arm/boot/compressed/head.S:698: Warning: (null) arch/arm/boot/compressed/head.S:722: Warning: (null) arch/arm/boot/compressed/head.S:726: Warning: (null) arch/arm/boot/compressed/head.S:957: Warning: (null) arch/arm/boot/compressed/head.S:996: Warning: (null) arch/arm/boot/compressed/head.S:997: Warning: (null) arch/arm/boot/compressed/head.S:1027: Warning: (null) arch/arm/boot/compressed/head.S:1035: Warning: (null) arch/arm/boot/compressed/head.S:1046: Warning: (null) arch/arm/boot/compressed/head.S:1060: Warning: (null) arch/arm/boot/compressed/head.S:1092: Warning: (null) arch/arm/boot/compressed/head.S:1094: Warning: (null) arch/arm/boot/compressed/head.S:1095: Warning: (null) arch/arm/boot/compressed/head.S:1102: Warning: (null) arch/arm/boot/compressed/head.S:1134: Warning: (null) Signed-off-by: Arnd Bergmann <arnd@arndb.de> Cc: Matthew Gretton-Dann <matthew.gretton-dann@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> [bwh: Backported to 3.2: - Adjust context - Remove definition of asflags-y as it is now empty] Signed-off-by: Ben Hutchings <ben@decadent.org.uk> Cc: Yang Yingliang <yangyingliang@huawei.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> 2014-04-14T13:44:19Z Shawn Guo shawn.guo@linaro.org 2012-08-22T13:46:39Z urn:sha1:26b9386b0228d0760b0c9649bd9c952ebcee3fa0 commit a46d2619d7180bda12bad2bf15bbd0731dfc2dcf upstream.

This patch zeroes the SCTLR.TRE bit prior to setting the mapping as cacheable for ARMv7 cores in the decompressor, ensuring that the memory region attributes are obtained from the C and B bits, not from the page tables.

Since commit c7e963f (net/smsc911x: Add regulator support), the lan9220 device tree probe fails on imx53-ard board, because the commit makes VDD33A and VDDVARIO supplies mandatory for the driver. Add a fixed dummy 3V3 supplying lan9220 to fix the regression.

Cardhu's eMMC controller is on sdhci@78000600, not sdhci@78000400. Fix the typo. This roughly doubles the IO performance, since the support-8bit property actually takes effect.

Looking through the complex IRQ definition for the MMCI on the versatile (including an #if 1 statement forcing MMCI IRQ0 to the VIC) this appears to the the correct IRQ number for both models.
