* dfu: ram supportAfzal Mohammed2013-09-24-2/+83
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: <image name> ram <start address> <size> 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 enumAfzal Mohammed2013-09-24-13/+3
| | | | | | | | | | | | | | | 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, nand, ubi: add partubi alt settings for updating ubi partitionHeiko Schocher2013-08-26-2/+36
| | | | | | | | | | | | | | | | | | | | 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:ext4:fix Fix DFU upload functionalityŁukasz Majewski2013-07-03-4/+5
| | | | | | | | | | | | | | | 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.

SHA1: ea2453d56b8860dbd18a3c517531ffc8dcb5c839 The ext4{read|write} command formatting has been changed. It removed a write mandatory [sizebytes] parameter.

* dfu: Support larger than memory transfers.Pantelis Antoniou2013-04-10-89/+262
| | | | | | | | | | | | | | | | | | | Previously we didn't support upload/download larger than available memory. This is pretty bad when you have to update your root filesystem for example. This patch removes that limitation (and the crashes when you transfered any file larger than 4MB) by making raw image writes be done in chunks and making file maximum size be configurable. The sequence number is a 16 bit counter; make sure we handle rollover correctly. This fixes the wrong transfers for large (> 256MB) images. Also utilize a variable to handle initialization, so that we don't rely on just the counter sent by the host.
