* ratp: allow building without full console supportAleksander Morgado2018-03-015-6/+8
| | | | | | | | | | | | | Make CONFIG_RATP a selectable config option, so that the user can enable RATP support without explicitly needing to enable the full console support over RATP (e.g. only for RATP FS or built-in command support). The full console can still be explicitly enabled with CONFIG_CONSOLE_RATP. Signed-off-by: Aleksander Morgado <aleksander@aleksander.es> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* ratp: implement generic command supportAleksander Morgado2018-03-0116-18/+171
| | | | | | | | | | | | | | | | | | | The RATP implementation now allows executing generic commands with a binary interface: binary requests are received and binary responses are returned. Each command can define its own RATP request contents (e.g. to specify command-specific options) as well as its own RATP response contents (if any data is to be returned). Each command is associated with a pair of numeric unique request and response IDs, and for easy reference these IDs are maintained in the common ratp_bb header. Modules may override generic implemented commands or include their own new ones (as long as the numeric IDs introduced are unique).

* state: find backend node with its reproducible nameSascha Hauer2018-02-222-1/+6
| | | | | | | | | | | | When fixing up the kernels state nodes we depended on the full node path of the input device tree. This does not work when the kernel device tree has different names. This has happened lately when the i.MX6 device trees got their leading zeroes removed from the node names. Use of_find_node_by_reproducible_name() to find the node corresponding to the storage backend node in the kernel device tree. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* state: remove unused arguments from state_new_from_node()Sascha Hauer2018-02-224-32/+19
| | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Hauer2018-01-252-0/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

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

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>
