Robust context attempts to perform a rendering that takes too long
whether due to an infinite loop in a shader or even just a rendering
operation that takes too long on the given hardware. This type of
attempts can result into GPU faults. Robust context expect driver
to replay IB instead skip IB and if it fails on replay context has
to be invalidated.
KGSL_CONTEXT_INVALIDATE_ON_FAULT flag allows draw context to execute
only replay policy on GPU fault recovery instead of going to default
recovery policy. User space has to set this flag during the context
creation.

kgsl_ioctl_gpu_sparse_command() is added to for user to
specify list of binds/unbinds for a memory entry
and syncpoints they depend on. If user specifies both
create a sync object for syncpoints and bind object for
binds/unbinds and add them to dispatcher draw queue. Sync
object should be inserted before the bind object in the
draw queue. Once the bind object reaches the head of
draw queue the corresponding binds/unbinds are performed.
kgsl_ioctl_gpu_sparse_command() only accepts commands from
context created with flag KGSL_CONTEXT_SPARSE, commands
from all other context types will return an error.

Add support to allocate/reserve a virtual address range without
physically backing. Add support to allocate physically backing memory
without assigning it a virtual address. Add support to unite
the two forementioned allocations together. Add support to
divorce them from one another. Add support to let their kids
do cache operations as they see fit.
Create a 'dummy' page that is used to back virtual allocations
that are not yet backed by physical memory.

Some test applications intentionally generate a GPU fault for
various reasons. Because a GPU fault generates a snapshot and
snapshots are persistent until they are pulled, running the test
application may take up the snapshot slot and prevent a real fault
from being captured and debugged.
This flag allows the draw context to intentionally avoid generating
a snapshot.

Add the property to determine GPU bitness which
is used by the clients via KGSL ioctl.
Certain clients of KGSL such as Open-CL driver
need to know explicitly about the GPU mode.

On 5XX targets we need to program the bit of the highest DDR bank
into a number of registers, one of which is protected which would
cause problems if the user mode driver tried to write to it.
Specify the high bank bit in the device tree files, set the
problematic register in the kernel and then pass the value up to
the user mode driver as a property and let them program the
other registers. This makes the device tree the authoratative
source of the high bit value which is exactly how it should be.
If the value isn't specified by the device tree for whatever reason
return an error for the property request - that will give the UMD
a clue that the value wasn't specified and they should just set a
default.
