fastboot: sparse: improve CHUNK_TYPE_FILL write performance

2016-06-27T20:37:39Z

- increase the size of the fill buffer - testing has shown a 10x improvement when the sparse image has large CHUNK_TYPE_FILL chunks Signed-off-by: Steve Rae

fastboot: sparse: implement reserve()

2016-06-27T20:37:39Z

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. Signed-off-by: Steve Rae Reviewed-by: Maxime Ripard

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

2016-06-27T20:37:38Z

- 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 Signed-off-by: Steve Rae

fastboot: sparse: remove session-id logic

2016-06-27T20:36:33Z

This "session-id" alogrithm is not required, and currently corrupts the stored image whenever more the one "session" is required. Signed-off-by: Steve Rae

fastboot: sparse: remove unnecessary logging

remove logging of the 'skipped' blocks Signed-off-by: Steve Rae Acked-by: Maxime Ripard

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

2016-04-12T00:48:29Z

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"... Signed-off-by: Steve Rae Acked-by: Maxime Ripard

fastboot: sparse: fix sparse blocks calculation

2016-04-11T16:44:37Z

It may overflow in sparse_block_size_to_storage, use uint64_t instead in the calculation. Signed-off-by: Jeffy Chen

sparse: Rename the file and header

2015-11-12T18:18:59Z

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. Signed-off-by: Maxime Ripard Reviewed-by: Tom Rini
