* dfu: mmc: file buffer: remove static allocationPrzemyslaw Marczak2015-03-09-3/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For writing files, DFU implementation requires the file buffer with the len at least of file size. For big files it requires the same big buffer. Previously the file buffer was allocated as a static variable, so it was a part of U-Boot .bss section. For 32MiB len of buffer we have 32MiB of additional space, required for this section. The .bss needs to be cleared after the relocation. This introduces an additional boot delay at every start, but usually the dfu feature is not required at the standard boot, so the buffer should be allocated only if required. This patch removes the static allocation of this buffer, and alloc it with memalign after first call of function: - dfu_fill_entity_mmc() and the buffer is freed on dfu_free_entity() call. This was tested on Trats2. A quick test with trace. Boot time from start to main_loop() entry: - ~888ms - before this change (arch memset enabled for .bss clear) - ~464ms - after this change Signed-off-by: Przemyslaw Marczak <p.marczak@samsung.com> Reviewed-by: Simon Glass <sjg@chromium.org> Cc: Lukasz Majewski <l.majewski@samsung.com> Cc: Stephen Warren <swarren@nvidia.com> Cc: Pantelis Antoniou <panto@antoniou-consulting.com> Cc: Tom Rini <trini@konsulko.com> Cc: Marek Vasut <marek.vasut@gmail.com>

* dfu: dfu_get_buf: check the value of env dfu_bufsiz before usePrzemyslaw Marczak2014-12-18-2/+6
| | | | | | | | | | | | | | | | | | | In function dfu_get_buf(), the size of allocated buffer could be defined by the env variable. The size from this variable was passed for memalign() without checking its value. And the the memalign will return non null pointer for size 0. This could possibly cause data abort, so now the value of var is checked before use. And if this variable is set to 0 then the default size will be used. This commit also changes the base passed to simple_strtoul() to 0. Now decimal and hex values can be used for the variable dfu_bufsiz.

* dfu: Provide means to find difference between dfu-util -e and -RLukasz Majewski2014-09-02-5/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit provides distinction between DFU device detach and reset. The -R behavior is preserved with proper handling of the dfu-util's -e switch, which detach the DFU device. By running dfu-util -e; one can force device to finish the execution of dfu command on target and execute some other scripted commands. Moreover, some naming has been changed - the dfu_reset() method now is known as dfu_detach(). New name better reflects the purpose of the code. It was also necessary to increase the number of usb_gadget_handle_interrupts() calls since we also must wait for detection of the USB reset event. Example usage: 1. -e (detach) switch dfu-util -a0 -D file1.bin;dfu-util -a3 -D uImage;dfu-util -e access to u-boot prompt. 2. -R (reset) switch dfu-util -a0 -D file1.bin;dfu-util -R -a3 -D uImage target board reset Signed-off-by: Lukasz Majewski <l.majewski@samsung.com> Reviewed-by: Stephen Warren <swarren@nvidia.com> Tested-by: Stephen Warren <swarren@nvidia.com>

* dfu: allow backend to specify a maximum buffer sizeStephen Warren2014-08-09-5/+8
| | | | | | | | | | | | 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>

* dfu: add write error handlingStephen Warren2014-08-09-18/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* dfu: fix some issues with reads/uploadsStephen Warren2014-08-09-21/+76
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

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

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