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.

dfu: Extract common DFU code to handle "dfu_alt_info" environment variable

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

New dfu_init_env_entities() function has been extracted from cmd_dfu.c and
stored at dfu core.

This is a dfu centric code, so it shall be processed in the core.

dfu, nand, ubi: add partubi alt settings for updating ubi partition

2013-08-26T19:56:34+00:00

updating an ubi partition needs a completely erased mtd partition,
see:
http://lists.infradead.org/pipermail/linux-mtd/2011-May/035416.html

So, add partubi alt setting for the dfu_alt_info environment
variable to mark this partition as an ubi partition. In case we
update an ubi partition, we erase after flashing the image into the
partition, the remaining sektors.

dfu: Implementation of target reset after communication with dfu-util's -R switch

2013-07-29T21:01:33+00:00

This patch extends dfu code to support transmission with -R switch
specified at dfu-util.

When -R is specified, the extra USB_REQ_DFU_DETACH request is sent after
successful data transmission. Then dfu resources are released and reset
command is issued.

dfu:ext4:fix Fix DFU upload functionality

2013-07-03T12:41:23+00:00

For the first eMMC read of data for upload, use the "large" dfu_buf (now
configurable) instead of usb request buffer allocated at composite layer
(which is 4KiB) [*].

For eMMC the whole file is read, which usually is larger than the buffer [*]
provided with usb request.

dfu:ext4:fix Fix ext4{read|write} command formatting

2013-07-03T12:41:23+00:00

In the following commit:
"dfu: Support larger than memory transfers."
SHA1: ea2453d56b8860dbd18a3c517531ffc8dcb5c839

The ext4{read|write} command formatting has been changed. It removed
a write mandatory [sizebytes] parameter.

It extents DFU_FS_EXT4 case at mmc_file_op to provide mandatory
parameter for DFU write.
