[U-Boot] [PATCH v5 0/6] Qualcomm SMEM driver

[Ramon Fried]

This patchset introduces Qualcomm's shared memory manager.
In U-boot context, it will allow reading board specific information
(IE. RAM address, RAM size) that was prepopulated by the SBL.

As part of the patchset a new uclass id is introduced, UCLASS_SMEM.

Changes in v5:
(As suggested by Simon Glass)
- Add more documentation to smem.h describing item/host parameters.

Changes in v4:
- Fixed typo in function name.

Changes in v3:
(As suggested by Simon Glass)
- Fixed line wrap
- Fixed smem_get_free_space() interface to match smem_get_free_space()
- Added more documentation to ops.
- Removed license, SPDX is enough.
- Text and grammar fixes.
- Adapt to smem_get_free_space() new interface in series 3.

Changes in v2:
(As suggested by Simon Glass)
- Introduced a new dm class (CLASS_SMEM) instead of CLASS_SOC.
- Added sandbox driver
- Added testing for DM class.
- Applied checkpatch fixes (also sent these to Linux upstream)
- Changed UCLASS_SOC to UCLASS_SMEM
- Removed function exports and registered functionality through .ops
