* 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.

* dfu:ext4:fix: Change ext4write command order of parametersŁukasz Majewski2013-04-08-2/+2
| | | | | | | | | | | | | | Following commit: "cmd_ext4: BREAK and correct ext4write parameter order" SHA1:0171d52c410cbaa9290b1b214e695697c835bfe5 introduced cleanup of ext4write semantics to be consistent with other filesystem's writing commands (e.g. fatwrite). This commit provides correct ext4write command generation at DFU eMMC code. Signed-off-by: Lukasz Majewski <l.majewski@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com>

* dfu: DFU backend implementationLukasz Majewski2012-09-01-0/+281
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.
