fastboot: sparse: improve CHUNK_TYPE_FILL write performance

2016-06-27T20:37:39+00:00

- increase the size of the fill buffer
- testing has shown a 10x improvement when the sparse image
  has large CHUNK_TYPE_FILL chunks

fastboot: sparse: implement reserve()

2016-06-27T20:37:39+00:00

In order to process the CHUNK_TYPE_DONT_CARE properly, there is
a requirement to be able to 'reserve' a specified number of blocks
in the storage media. Because of the special handling of "bad blocks"
in NAND devices, this is implemented in a storage abstraction function.

fastboot: sparse: resync common/image-sparse.c (part 2)

2016-06-27T20:37:38+00:00

- update fastboot_okay() and fastboot_fail()

This file originally came from upstream code.

While retaining the storage abstraction feature, this is the second
set of the changes required to resync with the
  cmd_flash_mmc_sparse_img()
in the file
  aboot.c

fastboot: sparse: remove session-id logic

2016-06-27T20:36:33+00:00

This "session-id" alogrithm is not required, and currently corrupts
the stored image whenever more the one "session" is required.

fastboot: sparse: fix block addressing for don't care chunk type

2016-04-12T00:48:29+00:00

When 7bfc3b1 (sparse: Refactor chunk parsing function) was implemented,
it dropped 9981945 (aboot: fix block addressing for don't care chunk type).

This re-implements the required fix for the "don't care chunk type"...

fastboot: sparse: fix sparse blocks calculation

2016-04-11T16:44:37+00:00

It may overflow in sparse_block_size_to_storage, use uint64_t instead in
the calculation.

sparse: Rename the file and header

2015-11-12T18:18:59+00:00

The Android sparse image format is currently supported through a file
called aboot, which isn't really such a great name, since the sparse image
format is only used for transferring data with fastboot.

Rename the file and header to a file called "sparse", which also makes it
consistent with the header defining the image structures.
