Andre PrzywaraandMaxime Ripard a722359de4 SPL: SPI: select SPL_SPI_FLASH_SUPPORT on SPL_SPI_SUNXI
The Allwinner SPI flash SPL boot support is guarded by the SPL_SPI_SUNXI
symbol. But despite its generic name, the actual only use case for this
is to provide SPI flash support to the SPL, which requires
CONFIG_SPL_SPI_FLASH_SUPPORT to be defined.
Select this symbol from the SPL_SPI_SUNXI Kconfig definition. This
avoids doing this explicitly in the defconfig, and fixes SPI booting on
the Pine64 SoPine (and -LTS version) and the OrangePi Win board (both with
SPI flash).

Bin Meng febdfaabc7 x86: baytrail: Fix unstable ACPI S3 resume
It was observed that when booting a Ubuntu 16.04 kernel, doing ACPI
S3 suspend/resume sometimes causes the Ubuntu kernel hang forever.
The issue is however not reproduced with a kernel built from i386/
x86_64 defconfig configuration.

The unstability is actually caused by unexpected interrupts being
generated during the S3 resume. For some unknown reason, FSP (gold4)
for BayTrail configures the GPIO DFX5 PAD to enable level interrupt
(bit 24 and 25). As this pin keeps generating interrupts during an
S3 resume, and there is no IRQ requester in the kernel to handle it,
the kernel seems to hang and does not continue resuming.

Clear the mysterious interrupt bits for this pin.

Vishal MahaveerandTom Rini 3f3607ded4 arm: dra7xx: Add vendor partition to Android GPT table for eMMC
Add vendor partition to Android GPT table for eMMC.

A Vendor image contains SoC-specific code and configuration.

Prior to Android 8.0, the vendor partition was optional ;
files belonging to these images were placed in boot.img or system.img
with symlinks (such as /vendor >/system/vendor ) when absent.

Android 8.0 makes the vendor partition mandatory

The goal is to modularize Android partitions with standard interface between
the Android Platform (on system.img ) and vendor-provided code(on vendor.img).

This standard interface enables the Android Platform to be updated
without affecting the SoC partitions. This makes it possible to upgrade a
device system.img from Android 8.0 to Android P while other images (such as
vendor.img) remain at Android 8.0. This modularity enables timely
Android platform upgrades (such as monthly security updates )
without requiring SoC/ODM partners to update SoC- and device-specific code.

Praneeth BajjuriandTom Rini d5a42f6634 arm: am57xx: Add vendor partition to Android GPT table for eMMC
Add vendor partition to Android GPT table for eMMC.

A Vendor image contains SoC-specific code and configuration.

Prior to Android 8.0, the vendor partition was optional ;
files belonging to these images were placed in boot.img or system.img
with symlinks (such as /vendor >/system/vendor ) when absent.

Android 8.0 makes the vendor partition mandatory

The goal is to modularize Android partitions with standard interface between
the Android Platform (on system.img ) and vendor-provided code(on vendor.img).

This standard interface enables the Android Platform to be updated
without affecting the SoC partitions. This makes it possible to upgrade a
device system.img from Android 8.0 to Android P while other images (such as
vendor.img) remain at Android 8.0. This modularity enables timely
Android platform upgrades (such as monthly security updates )
without requiring SoC/ODM partners to update SoC- and device-specific code.
