| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Detecting reset reason is, in some cases, a destructive operation and in such cases it is impossible to obtain that information in the kernel without some help from barebox. Pass reset source and reset source instance to kernel to Linux to make it availible to Linux userspace. This info is placeed under /chosen/bootsource and it can be read under Linux in /sys/firmware/devicetree/base/chosen/reset-source. and /sys/firmware/devicetree/base/chosen/reset-source-instance.

| * | serdev: Allow polling interval to be adjusted at runtimeAndrey Smirnov2018-04-171-1/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to blocking, synchronous, polling driven nature of Barebox's serial communication handling trying to use two or more serial ports at high (1Mbaud+) baudrates results in data loss and noticeable perofmance degradation. This happens as soon as individual message being sent around start exceeding HW Rx FIFO in size. A good example of such a usecase would be using a system that has a serdev driver (operating @ 1Mbaud+) and trying to do a X/YMODEM transfer via serial console at comparable baudrates. To at least partially ameliorate the problem, add code that will expose "polling_interval" as a parameter, so that the user would have an option of temporarily disabling (or significatly decreasing the rate) of a given serdev's polling.

* / 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.

| * 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).
