In order to avoid license problem of Cadence header files, these
license files has been wrappered into a library and new interface
has been abstracted to replace the interface of Cadence header
files.So update the mxc_hifi4.h file to provide new interface for
user space to use.Signed-off-by: Weiguang Kong

This change allows userland to create a tee_shm object that refers
to a dmabuf reference.Userland provides a dmabuf file descriptor as buffer reference.
The created tee_shm object exported as a brand new dmabuf reference
used to provide a clean fd to userland. Userland shall closed this new
fd to release the tee_shm object resources. The initial dmabuf resources
are tracked independently through original dmabuf file descriptor.Once the buffer is registered and until it is released, TEE driver
keeps a refcount on the registered dmabuf structure.This change only support dmabuf references that relates to physically
contiguous memory buffers.New tee_shm flag to identify tee_shm objects built from a registered
dmabuf: TEE_SHM_EXT_DMA_BUF. Such tee_shm structures are flagged both
TEE_SHM_DMA_BUF and TEE_SHM_EXT_DMA_BUF.Signed-off-by: Etienne Carriere

Initial patch for generic TEE subsystem.
This subsystem provides:
* Registration/un-registration of TEE drivers.
* Shared memory between normal world and secure world.
* Ioctl interface for interaction with user space.
* Sysfs implementation_id of TEE driverA TEE (Trusted Execution Environment) driver is a driver that interfaces
with a trusted OS running in some secure environment, for example,
TrustZone on ARM cpus, or a separate secure co-processor etc.The TEE subsystem can serve a TEE driver for a Global Platform compliant
TEE, but it's not limited to only Global Platform TEEs.This patch builds on other similar implementations trying to solve
the same problem:
* "optee_linuxdriver" by among others
Jean-michel DELORME and
Emmanuel MICHEL
* "Generic TrustZone Driver" by Javier GonzálezAcked-by: Andreas Dannenberg

In pxp lib, the unit of stride parameter is pixel and stride
is not equal with width parameter of out buffer in some cases.In order to use latest pxp lib in old version rootfs, PXP_DEVICE_LEGACY
macro is used to distinguish pxp drvier version. Because the
new pxp driver define a new variable and pxp lib can know this
through PXP_DEVICE_LEGACY, and determine if use it.Signed-off-by: Guoniu.Zhou

This driver allows rpmsg instances to expose access to rpmsg endpoints
to user space processes. It provides a control interface, allowing
userspace to export endpoints and an endpoint interface for each exposed
endpoint.The implementation is based on prior art by Texas Instrument, Google,
PetaLogix and was derived from a FreeRTOS performance statistics driver
written by Michal Simek.The control interface provides a "create endpoint" ioctl, which is fed a
name, source and destination address. The three values are used to
create the endpoint, in a backend-specific way, and a rpmsg endpoint
device is created - with the three parameters are available in sysfs for
udev usage.E.g. to create an endpoint device for one of the Qualcomm SMD channel
related to DIAG one would issue:struct rpmsg_endpoint_info info = { "DIAG_CNTL", 0, 0 };
int fd = open("/dev/rpmsg_ctrl0", O_RDWR);
ioctl(fd, RPMSG_CREATE_EPT_IOCTL, &info);Each created endpoint device shows up as an individual character device
in /dev, allowing permission to be controlled on a per-endpoint basis.
The rpmsg endpoint will be created and destroyed following the opening
and closing of the endpoint device, allowing rpmsg backends to open and
close the physical channel, if supported by the wire protocol.Cc: Marek Novak

in previous flow, when all LUTs are used, the LUT cleanup operation
need to wait for all the LUT to finish, it will not happen util last LUT
is done. while in new flow, the cleanup operation does not need to wait
for all LUTs to finish, instead it can start when there's LUT's done.
