2c72404687 fastboot: sparse: implement reserve()
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.

9bc34799c8 fastboot: sparse: resync common/image-sparse.c (part 2)
- 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
from
  https://us.codeaurora.org/cgit/quic/la/kernel/lk/plain/app/aboot/aboot.c?h=LE.BR.1.2.1

64ece84854 fastboot: sparse: remove session-id logic
This "session-id" alogrithm is not required, and currently corrupts
the stored image whenever more the one "session" is required.

61717571f2 common: fb_nand: won't compile
Somehow this got overlooked when getting rid of nand_info.

Small patch, won't affect anything else, no reason to wait for the
next cycle.

b616d9b0a7 nand: Embed mtd_info in struct nand_chip
nand_info[] is now an array of pointers, with the actual mtd_info
instance embedded in struct nand_chip.

This is in preparation for syncing the NAND code with Linux 4.6,
which makes the same change to struct nand_chip.  It's in a separate
commit due to the large amount of changes required to accommodate the
change to nand_info[].

This typedef serves no purpose other than causing confusion with
struct nand_chip.

3d4ef38de2 sparse: Rename the file and header
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.

6fb77c48e4 fastboot: nand: Add pre erase and write hooks
Some devices might need to do some per-partition initialization
(ECC/Randomizer settings change for example) before actually accessing it.

Add some hooks before the write and erase operations to let the boards
define what they need to do if needed.

bf8940d35b fastboot: Implement NAND backend
So far the fastboot code was only supporting MMC-backed devices for its
flashing operations (flash and erase).

Add a storage backend for NAND-backed devices.
