* of: mtd: partition: Use reproducible node names for fixupSascha Hauer2018-02-061-1/+4
| | | | | | | | | | The full names of device nodes are not as stable as we like them to be. Lately the leading zeroes in the i.MX6 device trees were removed which led to the result that we can no longer find the partition nodes in the to be fixed tree. Use reproducible names to overcome this. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* of: Add function to find the same node in another treeSascha Hauer2018-02-062-1/+67
| | | | | | | | | | | | For our device tree fixups we have to find a node corresponding to another node in another device tree. We used to use the full name to match the nodes, but this falls apart when nodes get renamed or for example a new bus hierarchy is introduced. To make this more robust we create reproducible names from device nodes which mostly depend on the address in MMIO space, the reg property and as a last resort the name of the device node.

| | | | | | | | | | | | | | | | | | | | | | | | Currently all upstream boards use the same barebox-environment setup. It is however problematic to add new boards, that have a different setup.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The SWITCH command has two purposes: a) switch the command set b) Write to the EXT_CSD register If the access field (bits [25:24]) in the argument are b00, we're in case a), otherwise in b). As mci_switch() always passes MMC_SWITCH_MODE_WRITE_BYTE (0b3) in the access field, only case b) is relevant here. According to the eMMC specification[1] the command set field is ignored in case b) and so the respective parameter (that is unused already now) can be dropped.

| * | partitions: dos: Treat all extended partition types equallyAndrey Smirnov2018-01-221-7/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Creating logical DOS partitions with fdisk (Fedora 27, fdisk from util-linux 2.30.2) results in extended partition of type 0x05 being created on the device. Partitioned like this, device is succesfully recognized by Linux, but, due to algorithm in dos_partition(), not Barebox. Looking closer at the actual contents of MBR shows that while marked as "Extended partition with CHS addressing" that partition still have all of the LBA adressed fields filled correctly. Given the above and the fact that similar code in Linux kernel (block/partitions/msdos.c) does not make a distinction between types 0x0f and 0x05, port Linux's is_extended_partition() and convert the code to treat types 0x05, 0x0f and 0x85 the same way.

| * | | usb: gadget: fastboot: Add sparse image supportSascha Hauer2018-01-183-23/+232
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sparse images are needed for fastboot to flash images that do not fit into memory. Android fastboot is kind of a dumb protocol. It first sends you a big image and afterwards it tells you where to put this image. This of course limits fastboot to files smaller than the available memory. To bypass this issue fastboot has so called Sparse image support. This is a new image format that can contain holes in the data so a big image can be written in multiple steps with holes in other areas each step. Implementing this for UBI images is kind of tricky since ubiformat normally expects to get a single image. Preparations to ubiformat a device in multiple parts have been done in previous patches. It is however, only for the first part possible to detect if it is a UBI image. The other parts are just binary data and we cannot know if we have to pass this data raw to the flash or use ubiformat. For this reason this patch makes the 'u' flag in the partition description mandatory for proper UBI image flashing on MTD devices. fastboot passes a max_download_size variable to the host. This variable contains the image size fastboot can take in one go. We have to choose a good compromise here. On one hand we do not want to risk that we actually do not have enough memory to hold the transferred image, on the other hand we want images like bootloaders not as sparse images, but in one go instead to make atomic exchange of the bootloader possible. Right now we have chosen 8MiB which should be big enough for all bootloaders. The value is configurable via global.usbgadget.fastboot_max_download_size.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This flag is added to better support flashing UBI image with Android sparse images. Android fastboot splits images which are bigger than the free memory into multiple images which are then transferred in multiple fastboot sessions. In a session which is not the first one we can no longer detect if an image is a UBI image or not, so we need a flag to make this explicit. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

With upcoming Android fastboot sparse image support we can no longer provide a complete image anymore. With this patch we can write an image in multiple chunks after we've formatted a MTD device with ubiformat. ubiformat_write will skip the EC header in both the MTD device we write to and also the image we read from, so we can flash an image on a MTD device containing EC headers already.
