* rename file_operations -> cdev_operationsSascha Hauer2018-04-062-2/+2
| | | | | | | | Linux also has struct file_operations which are something different. Rename our file_operations to cdev_operations which better matches what we have. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* Revert "startup: Load default environment earlier"Sascha Hauer2018-03-191-3/+3
| | | | | | | | | | | | | | | | Several boards use defaultenv_append_directory() to append a board specific envfs snippet during runtime. This only works when defaultenv_append_directory() is called before defaultenv_load() is exectuted. Since that was executed at the end of the start process every initcall level could be used to append a env directory. With this patch only initcall levels earlier than fsdevice_initcall work and most boards do not cope with this. Revert this patch until a better solution is found. Reported-by: Alexander Kurz <akurz@blala.de> This reverts commit 5b92cfceff38f3a6462a21cf6b69159ad0ae9744.

| * ratp: new md and mw commandsAleksander Morgado2018-03-013-0/+377
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Morgado2018-03-012-16/+68
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* | FIT: Implement opening images with no configurationSascha Hauer2018-02-081-7/+75
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | different images can be grouped together to build a FIT configuration. So far we only supported opening images as parts of configurations. This patch adds support for opening images that are not part of a configuration. This mode is used when the configuration parameter of fit_open_image is NULL. The main difference is in the way the RSA signature is checked. When being part of a configuration all involved nodes (including the hash nodes of the images, but not the image itself) are covered by the signature, thus during opening an image only the validity of the image data hash has to be checked. When not being part of a configuration, the image data itself is signed and must be checked. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Preparation for the next step which will allow to open images which are not part of a configuration. This has one change inside: We used to iterate over all subnodes of a image expecting all of them containing a hash, so it could happen that we check multiple hashes if more exist or that we falsely interpret some unrelated subnode as hash node. With this patch we expect the hash in a subnode named "hash@1" as required by the FIT image format description. 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. So far we only supported the latter. To prepare supporting the former we return a cookie belonging to the configuration from fit_open_configuration() which we use in fit_open_image() to refer to the desired configuration.

| * 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.
