| * ratp: new md and mw commandsAleksander Morgado2018-03-011-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit introduces support for running the md and mw commands using the binary interface provided by RATP. This allows clients to read and write memory files without needing to do custom string parsing on the data returned by the console 'md' and 'mw' operations. The request and response messages used for these new operations are structured in the same way: * An initial fixed-sized section includes the fixed-sized variables (e.g. integers), as well as the size and offset of the variable-length variables. * After the initial fixed-sized section, the buffer is given, which contains the variable-length variables in the offsets previously defined and with the size previously defined. The message also defines separately the offset of the buffer w.r.t. the start of the message. The endpoint reading the message will use this information to decide where the buffer starts. This allows to extend the message format in the future without needing to break the message API, as new fields can be appended to the fixed-sized section as long as the buffer offset is also updated to report the new position of the buffer. E.g.: $ ./bbremote --port /dev/ttyUSB2 md /dev/pic_eeprom_rdu 0x107 5 0000000000 $ ./bbremote --port /dev/ttyUSB2 mw /dev/pic_eeprom_rdu 0x107 0102030405 5 bytes written $ ./bbremote --port /dev/ttyUSB2 md /dev/pic_eeprom_rdu 0x107 5 0102030405 $ ./bbremote --port /dev/ttyUSB2 mw /dev/pic_eeprom_rdu 0x107 0000000000 5 bytes written $ ./bbremote --port /dev/ttyUSB2 md /dev/pic_eeprom_rdu 0x107 5 0000000000 Signed-off-by: Aleksander Morgado <aleksander@aleksander.es> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * ratp: implement generic command supportAleksander Morgado2018-03-012-0/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

| * | usb: gadget: fastboot: Add external command execution supportSascha Hauer2018-02-091-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Custom projects may need vendor specific expansions to the fastboot command execution. Allow these to be implemented without messing in the fastboot code directly. We have a hook for all commands and also one for the "flash" command. Each hook can decide if the generic command parser is executed afterwards (return value FASTBOOT_CMD_FALLTHROUGH) or if the generic parser shall be skipped (return value 0 or negative error code). This allows board code to implement vendor specific "oem" commands or to handle the downloaded image in a special way (i.e. do signature checks on them) 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>

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

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

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.
