2014-08-09dfu: add SF backendStephen Warren
This allows SPI Flash to be programmed using DFU. Signed-off-by: Stephen Warren <swarren@nvidia.com>
2014-08-09dfu: add free_entity() to struct dfu_entityStephen Warren
This allows the backend to free any resources allocated during the relevant dfu_fill_entity_*() call. This will soon be used by the SF backend. Signed-off-by: Stephen Warren <swarren@nvidia.com>
2014-08-09dfu: allow backend to specify a maximum buffer sizeStephen Warren
CONFIG_SYS_DFU_DATA_BUF_SIZE may be large to allow for FAT/ext layouts to transfer large files. However, this means that individual write operations will take a long time. Allow backends to specify a maximum buffer size, so that each write operation is limited to a smaller data block. This prevents the DFU protocol from timing out when e.g. writing to SPI flash. I would guess that NAND might benefit from setting this value too, but I can't test that. Signed-off-by: Stephen Warren <swarren@nvidia.com>
2014-08-09dfu: defer parsing of device string to IO backendStephen Warren
Devices are not all identified by a single integer. To support this, defer the parsing of the device string to the IO backed, so that it can apply the appropriate rules. SPI devices are specified as controller:chip_select. SPI/SF support will be added soon. MMC devices can also be specified as controller[.hwpart][:partition] in many commands, although we don't support that syntax in DFU. Signed-off-by: Stephen Warren <swarren@nvidia.com>
2014-08-09dfu: add write error handlingStephen Warren
Fix calls to dfu_write() and dfu_flush() to detect errors in the I/O itself. This could happen due to problems with the storage medium, or simply when trying to write a FAT/ext file that is larger than the buffer dfu_mmc.c maintains for this purpose. Signal the error by switching the DFU state/status. This will be picked up by the DFU client when it sends the next DFU request. Note that errors can't simply be returned from e.g. dnload_request_complete(), since that function has no way to pass errors back to the DFU client; a call to dnload_request_complete() simply means that a USB OUT completed. This error state/status needs to be cleared when the next DFU client connects. While there is a DFU_CLRSTATUS request, no DFU client seems to send this. Hence, clear this when selecting the USB alternate setting on the USB interface. Finally, dfu.c relies on a call to dfu_flush() to clear up the internal state of the write transaction. Now that errors in dfu_write() are detected, dfu_flush() may no longer be called for every transaction. Separate out the cleanup code into a new function, and call it whenever dfu_write() fails, as well as from any call to dfu_flush(). Signed-off-by: Stephen Warren <swarren@nvidia.com>
2014-08-09dfu: fix some issues with reads/uploadsStephen Warren
DFU read support appears to rely upon dfu->read_medium() updating the passed-by-reference len parameter to indicate the remaining size available for reading. dfu_read_medium_mmc() never does this, and the implementation of dfu_read_medium_nand() will only work if called just once; it hard-codes the value to the total size of the NAND device irrespective of read offset. I believe that overloading dfu->read_medium() is confusing. As such, this patch introduces a new function dfu->get_medium_size() which can be used to explicitly find out the medium size, and nothing else. dfu_read() is modified to use this function to set the initial value for dfu->r_left, rather than attempting to use the side-effects of dfu->read_medium() for this purpose. Due to this change, dfu_read() must initially set dfu->b_left to 0, since no data has been read. dfu_read_buffer_fill() must also be modified not to adjust dfu->r_left when simply copying data from dfu->i_buf_start to the upload request buffer. r_left represents the amount of data left to be read from HW. That value is not affected by the memcpy(), but only by calls to dfu->read_medium(). After this change, I can read from either a 4MB or 1.5MB chunk of a 4MB eMMC boot partion with CONFIG_SYS_DFU_DATA_BUF_SIZE==1MB. Without this change, attempting to do that would result in DFU read returning no data at all due to r_left never being set. Signed-off-by: Stephen Warren <swarren@nvidia.com>

Patch (SHA1: bd694244db7bc969954) dfu: Introduction of the "dfu_hash_algo" env variable for checksum method setting already introduced more generic handling of the crc32 calculation.

2014-06-01dfu: Introduction of the "dfu_hash_algo" env variable for checksum method ↵Lukasz Majewski
setting Up till now the CRC32 of received data was calculated unconditionally. The standard crc32 implementation causes long delay when large images were uploaded. The "dfu_hash_algo" environment variable gives the opportunity to disable on demand the hash (crc32) calculation. It can be done without the need to recompile the u-boot binary. By default the crc32 is calculated, which means that legacy behavior has been preserved.

2014-05-15dfu: mmc: Provide support for eMMC boot partition accessLukasz Majewski
Before this patch it was only possible to access the default eMMC HW partition. By partition selection I mean the access to eMMC via the ext_csd[179] register programming. It sometimes happens that it is necessary to write to other partitions. This patch adds extra attribute to "raw" sub type of the dfu_alt_info environment variable (e.g. boot-mmc.bin raw 0x0 0x200 mmcpart 1;) It saves the original boot value and restores it after storing the file.

2014-05-15drivers:dfu: dfu_flush(): add raw data flush to complete dfu writePrzemyslaw Marczak
Before dfu write and flush operations separation, dfu write data was flushed by host download request with len of zero size. Since above change manually calling dfu write with zero size has non sense (e.g. in THOR). This should be done by flush operation. So now dfu_write_buffer_drain() is called in dfu_flush(). If there is any raw data to flush (like it can be in thor) then it will be physically written to medium.

2014-05-05dfu: mmc: raw data write fixMateusz Zalega
When user attempted to perform a raw write using DFU (vide dfu_fill_entity_mmc) with MMC interface not initialized before, get_mmc_blk_size() reported invalid (zero) block size - it wasn't possible to write ie. a new u-boot image. This commit fixes that by initializing MMC device before use in dfu_fill_entity_mmc(). While fixing initialization sequence, I had to change about half of dfu_fill_entity_mmc's body, so I refactored it on the way to make it, IMHO, considerably more comprehensible. Being left as dead code, get_mmc_blk_size() was removed. Tested on Samsung Goni.

2014-03-23usb: dfu: introduce dfuMANIFEST stateHeiko Schocher
on nand flash using ubi, after the download of the new image into the flash, the "rest" of the nand sectors get erased while flushing the medium. With current u-boot version dfu-util may show: Starting download: [##################################################] finished! state(7) = dfuMANIFEST, status(0) = No error condition is present unable to read DFU status as get_status is not answered while erasing sectors, if erasing needs some time. So do the following changes to prevent this: - introduce dfuManifest state According to dfu specification ( http://www.usb.org/developers/devclass_docs/usbdfu10.pdf ) section 7: "the device enters the dfuMANIFEST-SYNC state and awaits the solicitation of the status report by the host. Upon receipt of the anticipated DFU_GETSTATUS, the device enters the dfuMANIFEST state, where it completes its reprogramming operations." - when stepping into dfuManifest state, sending a PollTimeout DFU_MANIFEST_POLL_TIMEOUT in ms, to the host, so the host (dfu-util) waits the PollTimeout before sending a get_status again.

2013-09-24dfu: ram supportAfzal Mohammed
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.

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.
