* dfu: defer parsing of device string to IO backendStephen Warren2014-08-09-9/+12
| | | | | | | | | | | | | | 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>
* dfu: fix some issues with reads/uploadsStephen Warren2014-08-09-9/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* dfu: mmc: Provide support for eMMC boot partition accessLukasz Majewski2014-05-15-0/+46
| | | | | | | | | | | | | | 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.

* dfu: mmc: change offset base handlingMateusz Zalega2014-05-05-2/+6
| | | | | | | | | | | | Previously offsets handled by dfu_fill_entity_mmc(), defined in boards' CONFIG_DFU_ALT were treated as hexadecimal regardless of their prefix, which sometimes led to confusion. This patch forces usage of explicit numerical base prefixes.

* dfu: mmc: raw data write fixMateusz Zalega2014-05-05-40/+65
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* dfu: mmc: Replace calls to u-boot commands with native mmc APIŁukasz Majewski2014-03-23-7/+24
| | | | | | | | | | | | | For some time we have been using the run_command() with properly crafted string. Such approach turned to be unreliable and error prone. Switch to "native" mmc subsystem API would allow better type checking and shall improve speed. Also, it seems that this API is changing less often than u-boot commands. The approach similar to env operations on the eMMC has been reused. Signed-off-by: Lukasz Majewski <l.majewski@samsung.com>

* dfu: unify mmc/nand read/write ops enumAfzal Mohammed2013-09-24-7/+2
| | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | 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.

* dfu: Support larger than memory transfers.Pantelis Antoniou2013-04-10-36/+72
| | | | | | | | | | | | | | | | | | | 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.
