Until properly solved, let's just remove the section in the device tree

…dation-v8 **not for mainline**

All the platforms that reserve memory for OP-TEE statically via the
DT (i.e., not those that reserve it via UEFI or that patch the DT
dynamically thanks to OP-TEE's CFG_DT option) have to mark it 'no-map'
so that only the TEE driver may map it.

This change fixes EV1 configuration which lacked OP-TEE
reserved memory. This change also makes ED1 board ready
the host OP-TEE by enabling OP-TEE node and defining the

these resources in ED1 DTS file which is included in EV1 DTS

This patch provides infrastructure for deferring buffer frees.

This is a feature ION provided which when used with some form
of a page pool, provides a nice performance boost in an
allocation microbenchmark. The reason it helps is it allows the
page-zeroing to be done out of the normal allocation/free path,
and pushed off to a kthread.

As not all heaps will find this useful, its implemented as
a optional helper library that heaps can utilize.

Bug: 168742043

This patch adds a simple shrinker controlled page pool to the
dmabuf heaps subsystem.

This replaces the use of the networking page_pool, over concerns
that the lack of a shrinker for that implementation may cause
additional low-memory kills

TODO: Take another pass at trying to unify this w/ the ttm pool

Thoughts and feedback would be greatly appreciated!

Bug: 168742043

add Linaro secure heap bindings: linaro,secure-heap
use genalloc to allocate/free buffer from buffer pool.
buffer pool info is from dts.
use sg_table instore the allocated memory info, the length of sg_table is 1.
implement secure_heap_buf_ops to implement buffer share in difference device:
1. Userspace passes this fd to all drivers it wants this buffer
to share with: First the filedescriptor is converted to a &dma_buf using
dma_buf_get(). Then the buffer is attached to the device using dma_buf_attach().
2. Once the buffer is attached to all devices userspace can initiate DMA
access to the shared buffer. In the kernel this is done by calling dma_buf_map_attachment()
3. get sg_table with dma_buf_map_attachment in difference device.

Add DMABUF_HEAPS_SECURE in defconfig

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.
