* dfu: add write error handlingStephen Warren2014-08-09-22/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | 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>

This patch adds opportunity to write Keystone U-boot image to NAND device using appropriate RBL ECC layout. This is needed only if RBL boots U-boot from NAND device and that's supposed that raw u-boot partition is used only for writing image. The main problem is that default Davinci ECC layout is different from Keystone RBL layout. To read U-boot image the RBL needs that image was written using RBL ECC layout. The BBT table is written using default Davinci layout and has to be updated using one. The BBT can be updated only while erasing chip or by forced bad block assigning, so erase function has to use native ecc layout in order to be able to write BBT correctly. So if we're writing to NAND U-boot address we use RBL layout for others we use default ECC layout. Also remove definition for CONFIG_CMD_NAND_ECCLAYOUT as there is no reasons to use ECC layout commands. It was added by mistake. Signed-off-by: Ivan Khoronzhuk <ivan.khoronzhuk@ti.com>

| | |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The DMA code in sunxi_mmc.c is broken. mmc_trans_data_by_dma() allocates the dma descriptors on the stack, and then exits while the dma transfer is in progress, so the dma engine is reading stack memory which at that point may be re-used. So far we've gotten away with this by luck, but recent u-boot changes have shifted the stack start address by 16 bytes, which combined with dma alignment now exposes this problem. Since we end up just busy waiting for the dma engine anyway, this commit fixes things by simply removing the dma code, resulting in smaller bug-free code.

Add functions to access a child in each of these ways. The index is typically used as a fallback when the sequence number is not available. For example we may use a serial UART with sequence number 0 as the console, but if no UART has sequence number 0, then we can fall back to just using the first UART (index 0). The device tree offset function is useful for buses, where they want to locate one of their children. The device tree can be scanned to find the offset of each child, and that offset can then find the device. Signed-off-by: Simon Glass <sjg@chromium.org>
