2019-10-29	drm/tegra: falcon: Clarify address usage	Thierry Reding	1	-2/+3
	Rename paddr -> iova and vaddr -> virt to make it clearer how these addresses are used. This is important for a subsequent patch that makes a distinction between the physical address (physical address of the system memory from the CPU's point of view) and the IOVA (physical address of the system memory from the device's point of view).

2019-10-29	drm/tegra: Remove memory allocation from Falcon library	Thierry Reding	1	-11/+0
	Having to provide allocator hooks to the Falcon library is somewhat cumbersome and it doesn't give the users of the library a lot of flexibility to deal with allocations. Instead, remove the notion of Falcon "operations" and let drivers deal with the memory allocations themselves. Signed-off-by: Thierry Reding <treding@nvidia.com>

2017-04-05	drm/tegra: Add falcon helper library	Arto Merilainen	1	-0/+127
	Add a set of falcon helper routines for use by the tegradrm client drivers of the various falcon-based engines. The falcon is a microcontroller that acts as a frontend for the rest of a particular Tegra engine. In order to properly utilize these engines, the frontend must be booted before pushing any commands.
