 Having capability to flash sparse images from mmc subsystem could be useful.
For example, non-android/fastboot platforms could leverage the concept. Or
some platforms that need to 'pull' updates (get images over tftp and flash
using mmc). Or when we want to flash image at some non-zero offset from the
start of a partition. Or simply when USB-Device has issues for fastboot
to work (my itch).

 This patchset first cleans and makes write_sparse_image agnostic of
fastboot and then adds a new 'swrite' command to 'mmc'. 

Jassi Brar (3):
  fastboot: sparse: remove redundant argument to write_sparse_image
  fastboot: sparse: make write_sparse_image useable for non-fastboot
  mmc: support writing sparse images
