* insmod/rmmod'ing works fine
* all interrupts are gotten etc.
* all basic functionality should be available

* several changes: tlkm_device contains all device data directly
* tlkm_class contains information relevant to a class of devices
  (e.g., pcie/zynq)
* classes are automatically enumerated at start, only access type
  is checked in create (device instances remain until unloaded)
* added micro-API for status core base queries

* tricky to get all refs in place for requesting while staying
  platform-neutral
* need to think about it some more

* independent of platform, using status core base addresses
* generic interrupt mechanism
* not implemented yet: DMA engines do not request interrupts

* libplatform now automatically logs the contents of perf when
  destroying the device
* fixed awkward platform_destroy_device: can be destroyed by
  pointer now, not only id

* building in main dir, like libplatform
* closely mirrored changes in libplatform: tapasco_ctx_t matches
  platform_ctx_t, and tapasco_devctx_t with platform_devctx_t
* this whole change requires a lot of changes all over the place
* tapasco-debug builds, but does not work yet
* tapasco-benchmark does not build yet

* read_mem and write_mem work now, too
* changed a few things, e.g., handing out DMA address now, instead of id
* works with platform-stress-alloc test (mode 1)
* default implementation should now be working

* changed allocation flags from GFP_DMA (obsolete, discouraged) to
  GFP_KERNEL | __GFP_MEMALLOC
* with >256MB CMA areas this should mean that we do not run into
  ENOMEMs soon, which could be confirmed
* however, DMA allocations tend to destabilize the system, sooner
  or later a memory oops will occur (see platform_stress_alloc)
* not sure how/if to fix that; thought leaving an FPGA-exclusive
  space on top of the DDR via mem= bootarg, but kernel does not
  boot below 500M
* will keep this for now

* minor memory leaks fixed
* destroy sequence fixed
* using DEV logging macros

* continued refactoring: some file renames in device/
* changed deactivate compile flag for performance counters to NPERFC
* re-inserted per-device perfc file with default output
* changed performance counter names and implemented counting
* implemented add function for counters to increase by more than 1
* added filename pattern to tlkm_device_ioctl_cmds.h

* fixed some bugs, mmapping works now
* also improved portability of read/write ioctls

* devices can set their mmap field to provide mmap-support
* reduced log chatter
* removed redundant struct tlkm_dev_cmd
* fixed bug in general read/write via ioctls

* libplatform and libtapasco can be built in the same location now
