mmc: Separate "mmc swrite" from fastboot

2018-05-30T09:59:21+00:00

Introduce CONFIG_IMAGE_SPARSE and CONFIG_CMD_MMC_SWRITE so the "mmc
swrite" command is separated from the fastboot code.

Move image-sparse from common to lib so it's clear it's library code.

Rename CONFIG_FASTBOOT_FLASH_FILLBUF_SIZE to CONFIG_IMAGE_SPARSE_FILLBUF_SIZE
and migrate it to Kconfig.

fastboot: Refactor fastboot_okay/fail to take response

2018-05-30T09:59:21+00:00

Add the response string as a parameter to fastboot_okay/fail, instead
of modifying a global, to match the contract expected by the AOSP
U-Boot code.

fastboot: sparse: make write_sparse_image useable for non-fastboot

2018-05-08T00:57:51+00:00

write_sparse_image could be useful for non-fastboot users.
For ex a platform, without usb-device/fastboot support, could
get sparse images over tftp and write using the mmc command.
Or non-android systems could also leverage the sparse format.

Towards that, this patch removes anything fastboot specific from
the write_sparse_image implementation. Which includes making the
function return integer as error code and calls for fastboot logging
via an optional callback function 'mssg'.

- 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: 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.
