armv8: Enable CPUECTLR.SMPEN for coherency

2016-07-08T21:16:49+00:00

For A53, data coherency is enabled only when the CPUECTLR.SMPEN bit is
set. The SMPEN bit should be set before enabling the data cache.
If not enabled, the cache is not coherent with other cores and
data corruption could occur.

For A57/A72, SMPEN bit enables the processor to receive instruction
cache and TLB maintenance operations broadcast from other processors
in the cluster. This bit should be set before enabling the caches and
MMU, or performing any cache and TLB maintenance operations.

arm: Fix setjmp (again)

2016-07-08T21:16:38+00:00

Commit e677724 (arm: Fix setjmp) added code to fix compilation of the setjmp
code path with thumv1. Unfortunately it missed a constraint that the adr
instruction can only refer to 4 byte aligned offsets.

So this patch adds the required alignment hooks to make compilation
work again even when setjmp doesn't happen to be 4 byte aligned.

video: tegra: Move to using simple-panel and pwm-backlight

2016-07-05T20:19:08+00:00

We have standard drivers for panels and backlights which can do most of the
work for us. Move the tegra20 LCD driver over to use those instead of custom
code.

This patch includes device tree changes for the nvidia boards. I have only
been able to test seaboard. If this patch is applied, these boards will
also need to be synced with the kernel, and updated to use display-timings:

   - colibri
   - medcom-wide
   - paz00
   - tec

Sync everything except the display panel, which will come in a future patch.
One USB port is left disabled since we don't want to support it in U-Boot.

sunxi: Add defconfig and DTS file for Allwinner R16 EVB (Parrot)

2016-07-02T11:53:15+00:00

The Parrot Board is an evaluation board with an Allwinner R16 (assumed
to be close to an Allwinner A33), 4GB of eMMC, 512MB of RAM, USB host
and OTG, a WiFi/Bluetooth combo chip, a micro SD Card reader, 2
controllable buttons, an LVDS port with separated backlight and
capacitive touch panel ports, an audio/microphone jack, a camera CSI
port, 2 sets of 22 GPIOs and an accelerometer.

The DTS file is identical to the one submitted to the upstream kernel.
