Add remoteproc resource handling helpers. These functions are primarily to parse the resource table and to handle different types of resources. Carveout, devmem, trace & vring resources are handled.

* as other entries might request placing other data objects inside
|
|
* these memory regions (e.g. data/code segments, trace resource entries, ...).
|
|
*
|
|
* Allocating memory this way helps utilizing the reserved physical memory
|
|
* (e.g. CMA) more efficiently, and also minimizes the number of TLB entries
|
|
* needed to map it (in case @rproc is using an IOMMU). Reducing the TLB
|
|
* pressure is important; it may have a substantial impact on performance.
|
|
*
|
|
* If the firmware is compiled with static addresses, then @da should specify
|
|
* the expected device address of this memory region. If @da is set to
|
|
* FW_RSC_ADDR_ANY, then the host will dynamically allocate it, and then
|
|
* overwrite @da with the dynamically allocated address.
|
|
*
|
|
* We will always use @da to negotiate the device addresses, even if it
|
|
* isn't using an iommu. In that case, though, it will obviously contain
|
|
* physical addresses.
|
|
*
|
|
* Some remote processors needs to know the allocated physical address
|
|
* even if they do use an iommu. This is needed, e.g., if they control
|
|
* hardware accelerators which access the physical memory directly (this
|
|
* is the case with OMAP4 for instance). In that case, the host will
|
|
* overwrite @pa with the dynamically allocated physical address.
|
|
* Generally we don't want to expose physical addresses if we don't have to
|
|
* (remote processors are generally _not_ trusted), so we might want to
|
|
* change this to happen _only_ when explicitly required by the hardware.
