dfu: Export allocated dfu buffer size

2013-12-18T18:53:19+00:00

The method for exporting size of allocated buffer is provided.
It is afterwards used by USB's dfu function code.

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).

dfu:core: Export dfu_{get|free}_buf functions

2013-10-20T21:42:40+00:00

Define the dfu_get_buf() and dfu_free_buf() as global functions.
They are necessary for zero copy buffer management, when DFU backend is
used for storing data.

dfu:core: Find DFU alt setting number by passing its name

2013-10-20T21:42:40+00:00

New function - dfu_get_alt() - has been added to dfu core. If present, it
returns alt setting's number corresponding to passed name.

usb: new board-specific USB init interface

2013-10-20T21:42:40+00:00

This commit unifies board-specific USB initialization implementations
under one symbol (usb_board_init), declaration of which is available in
usb.h.

New API allows selective initialization of USB controllers whenever needed.

dfu: ram support

2013-09-24T15:51:35+00:00

DFU spec mentions it as a method to upgrade firmware (software stored
in writable non-volatile memory). It also says other potential uses of
DFU is beyond scope of the spec.

Here such a beyond the scope use is being attempted - directly pumping
binary images from host via USB to RAM. This facility is a developer
centric one in that it gives advantage over upgrading non-volatile
memory for testing new images every time during development and/or
testing.

Directly putting image onto RAM would speed up upgrade process. This and
convenience was the initial thoughts that led to doing this, speed
improvement over MMC was only 1 second though - 6 sec on RAM as opposed
to 7 sec on MMC in beagle bone, perhaps enabling cache and/or optimizing
DFU framework to avoid multiple copy for ram (if worth) may help, and
on other platforms and other boot media like NAND maybe improvement
would be higher.

And for a platform that doesn't yet have proper DFU suppport for
non-volatile media's, DFU to RAM can be used.

Another minor advantage would be to increase life of mmc/nand as it
would be less used during development/testing.

usage:  ram  
eg. kernel ram 0x81000000 0x1000000

Downloading images to RAM using DFU is not something new, this is
acheived in openmoko also.

DFU on RAM can be used for extracting RAM contents to host using dfu
upload. Perhaps this can be extended to io for squeezing out register
dump through usb, if it is worth.

dfu: unify mmc/nand read/write ops enum

2013-09-24T15:51:35+00:00

MMC and NAND independently defines same enumerators for read/write.
Unify them by defining enum in dfu header. RAM support that is being
added newly also can make use of it.
