* dfu, nand, ubi: add partubi alt settings for updating ubi partitionHeiko Schocher2013-08-26-0/+2
| | | | | | | | | | | | | | | | | | | | 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 ↵Lukasz Majewski2013-07-29-0/+2
| | | | | | | | | | | | | | switch 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: make data buffer size configurableHeiko Schocher2013-06-30-1/+3
| | | | | | | | | | | | | | | | Dfu transfer uses a buffer before writing data to the raw storage device. Make the size (in bytes) of this buffer configurable through environment variable "dfu_bufsiz". Defaut value is configurable through CONFIG_SYS_DFU_DATA_BUF_SIZE Signed-off-by: Heiko Schocher <hs@denx.de> Cc: Pantelis Antoniou <panto@antoniou-consulting.com> Cc: Tom Rini <trini@ti.com> Cc: Lukasz Majewski <l.majewski@samsung.com> Cc: Kyungmin Park <kyungmin.park@samsung.com> Cc: Marek Vasut <marex@denx.de> Cc: Wolfgang Denk <wd@denx.de> Acked-by: Tom Rini <trini@ti.com>

* dfu: Support larger than memory transfers.Pantelis Antoniou2013-04-10-2/+22
| | | | | | | | | | | | | | | | | | | 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.

* dfu: DFU backend implementationLukasz Majewski2012-09-01-0/+103
New, separate driver at ./drivers/dfu has been added. It allows platform and storage independent operation of DFU. It has been extended to use new MMC level of command abstraction.
