dfu: mmc: Replace calls to u-boot commands with native mmc API

2014-03-23T01:20:10+00:00

For some time we have been using the run_command() with properly crafted
string. Such approach turned to be unreliable and error prone.

Switch to "native" mmc subsystem API would allow better type checking and
shall improve speed.

Also, it seems that this API is changing less often than u-boot commands.
The approach similar to env operations on the eMMC has been reused.

usb: dfu: introduce dfuMANIFEST state

2014-03-23T01:20:09+00:00

on nand flash using ubi, after the download of the new image into
the flash, the "rest" of the nand sectors get erased while flushing
the medium. With current u-boot version dfu-util may show:

Starting download: [##################################################] finished!
state(7) = dfuMANIFEST, status(0) = No error condition is present
unable to read DFU status

as get_status is not answered while erasing sectors, if erasing
needs some time.

So do the following changes to prevent this:

- introduce dfuManifest state
  According to dfu specification
  ( http://www.usb.org/developers/devclass_docs/usbdfu10.pdf ) section 7:
  "the device enters the dfuMANIFEST-SYNC state and awaits the solicitation
   of the status report by the host. Upon receipt of the anticipated
   DFU_GETSTATUS, the device enters the dfuMANIFEST state, where it
   completes its reprogramming operations."

- when stepping into dfuManifest state, sending a PollTimeout
  DFU_MANIFEST_POLL_TIMEOUT in ms, to the host, so the host
  (dfu-util) waits the PollTimeout before sending a get_status again.

usb, dfu: extract flush code into seperate function

move the flushing code into an extra function dfu_flush(),
so it can be used from other code.

usb: dfu: add static alt num count in dfu_config_entities()

2014-03-13T01:30:56+00:00

Thanks to this multiple call of function dfu_config_entities()
gives continuous dfu alt numbering until call dfu_free_entities().

This allows to store dfu entities in multiple variables.

The commit:

"EXT4: Fix number base handling of "ext4write" command"
 SHA1: f7740f7712b8638f08b83a7e5d00bc1d6bb086a9

Cleaned up the ext4write command format.

This commit shall be regarded as a follow up, since the DFU subsystem is

usb: dfu: make nand upload working

2013-11-08T19:46:20+00:00

Nowhere pass a value to len, which always 0, make no transfer which
cause uploading failed.

This patch make nand upload working. However it needs enough malloc
buffer to store read data, that means the buffer at least equal to
the upload partition size, or else it doesn't work.

usb: dfu: correct dfu buffer inited value

2013-11-08T19:46:20+00:00

After dfu buffer is initialized, the buffer should be all available,
while not 0. Initialize its value to min(dfu_buf_size, dfu->r_left).
