BeagleBoard-X15 is the next generation Open Source Hardware
BeagleBoard based on TI's AM5728 SoC featuring dual core 1.5GHz A15

eSATA, 3 USB3.0 ports, integrated HDMI (1920x1080@60), separate LCD
port, video In port, 4GB eMMC, uSD, Analog audio in/out, dual 1G
Ethernet.
For more information, refer to:
BeagleBoard-X15 Wiki:
http://www.elinux.org/Beagleboard:BeagleBoard-X15
AM5728 is part of the Sitara product family whose additional details
will be available: http://www.ti.com/lsds/ti/arm/overview.page
Technical Reference Manual for AM5728 is public domain at:
http://www.ti.com/lit/spruhz6
Just add basic support for the moment, the following updates are needed:
i) Ethernet - depends on SoC dts fixes
ii) USB Client (USB2) - depends on GPIO extcon
ii) HDMI - additional driver fixes pending
iii) Audio - additional driver fixes pending
NOTE:
AM5728 Data Manual (SPRS915L - August 2014) section 4.1.1 states: "All
unused power supply balls must be supplied with the voltages specified
in the Section 5.2, Recommended Operating Conditions". This implies
that all unused voltage rails for AM5728 can never be switched off even
if the hardware blocks inside that voltage domain is unused. Switching
off these unused rails may result in stability issues on other domains
and increased leakage and power-on-hour impacts.

ARM: dts: Use better omap GPMC timings for LAN9220
With the GPMC warnings now enabled, I noticed the LAN9220 timings
can overflow the GPMC registers with 200MHz L3 speed. Earlier we
were just skipping the bad timings and would continue with the
bootloader timings. Now we no longer allow to continue with bad
timings as we have the timings in the .dts files.
We could start using the GPMC clock divider, but let's instead
use the u-boot timings that are known to be working and a bit
faster. These are basically the u-boot NET_GPMC_CONFIG[1-6]
defines deciphered. Except that we don't set gpmc,burst-length
as that's only partially configured and does not seem to work
if fully enabled.

- A regression from 3.16 which was noticed in 3.17. With the
restructuring of the m25p80.c driver and the SPI NOR library
framework, we omitted proper listing of the SPI device IDs. This
means m25p80.c wouldn't auto-load (modprobe) properly when built as
a module. For now, we duplicate the device IDs into both modules.
- The OMAP / ELM modules were depending on an implicit link ordering.
Use deferred probing so that the new link order (in 3.18-rc) can
still allow for successful probing.

KVM: nVMX: Disable preemption while reading from shadow VMCS
In order to access the shadow VMCS, we need to load it. At this point,
vmx->loaded_vmcs->vmcs and the actually loaded one start to differ. If
we now get preempted by Linux, vmx_vcpu_put and, on return, the
vmx_vcpu_load will work against the wrong vmcs. That can cause
copy_shadow_to_vmcs12 to corrupt the vmcs12 state.
Fix the issue by disabling preemption during the copy operation.
copy_vmcs12_to_shadow is safe from this issue as it is executed by
vmx_vcpu_run when preemption is already disabled before vmentry.
This bug is exposed by running Jailhouse within KVM on CPUs with
shadow VMCS support. Jailhouse never expects an interrupt pending
vmexit, but the bug can cause it if, after copy_shadow_to_vmcs12
is preempted, the active VMCS happens to have the virtual interrupt
pending flag set in the CPU-based execution controls.
