* state: remove unused arguments from state_new_from_node()Sascha Hauer2018-02-221-2/+1
| | | | | | | | state_new_from_node() has arguments describing the backend path. These are never used in barebox, the backend path is always derived from the device nodes backend description. Remove these arguments. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * | libfile: implement a function to cache a fileSascha Hauer2018-01-251-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to the nature of TFTP which can't lseek and due to the silliness of our filesystem implementation which can't cache accesses we have to manually cache files on TFTP filesystems sometimes. Make it easier for them by providing a cache_file() function which copies the file from TFTP to RAM. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * | libfile: implement make_tempSascha Hauer2018-01-251-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Create a make_temp() function which creates a name for a temporary file. Since we do not have any concurrency in barebox we do not need to create the file right away and can leave that to the caller. Unlike unix mktemp the resulting filename is dynamically allocated and must be freed by the caller. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * | fs: implement is_tftp_fs()Sascha Hauer2018-01-251-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some commands need files in which they can lseek backwards which is particularly not possible on TFTP. Instead of hiding this behind can_lseek_backward() create a function for it which tests if the file is on TFTP directly rather than using different lseek operations.

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for const properties. We add a const void *value_const to struct property which will not be modified. The value of a property should no longer be used directly, but with the of_property_get_value() accessor which picks the right value. With this we can unflatten dtbs and use the property values directly from the dtb instead of copying them. This is useful for device trees which (ab)use properties to store huge data files, aka FIT images. To create a property whose value is not copied but used from the original input data we introduce of_new_property_const(). Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

They can be either opened directly based on their names in the images/ node or as part of a configuration based on their names in the corresponding /configuration/ node.

| |/ |/| | | | | | | | | | | | | | | | | | | | | 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.

| * mci: drop unused parameter from mci_switch()Uwe Kleine-König2018-01-221-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Android fastboot splits images which are bigger than the free memory into multiple images which are then transferred in multiple fastboot sessions.
