| * serdev: Add trivial blocking read functionAndrey Smirnov2018-04-171-0/+8
| | | | | | | | | | | | | | | | | | | | | | Add example implementation of a trivial blocking read function as a part of Barebox's serdev API. NOTE: This code has not been tested against real devices, so use it at your own risk. Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * console: Introduce console_drain()Andrey Smirnov2018-04-171-0/+84
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Generalize high baud rate UART polling code found in lib/xmodem.c and expose it as a generic function in console API. The usecase for this -- besides X/Y-mode data transfers where the code originated -- is command/reply type of serial exchages at high baud rates (~1Mbaud) with payloads exceeding inernal UART FIFOs in size. Such interactions are not uncommon in serdev device and this patch is done in preparation for serdev support code that will follow.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Using FIFO in LPUART results in subtle serial input draining issues which are quite difficult to reproduce and troubleshoot. Since the change offered only moderate performance gain revert the code to operate in no-FIFO mode to avoid FIFO-related problems alltogether.

| | | | | | | | | | | | | | | | | | | | In some cases it is practical to supervise as much as possible of the barebox execution with a watchdog (or multiple watchdogs).

* | dma: Add prototypes for dma mapping functionsSascha Hauer2018-03-291-0/+12
| | | | | | | | | | | | | | | | | | | | | | Right now we only have the dma_sync_single_* functions, but no functions for actually mapping a pointer. The mapping functions become necessary when casting a pointer to unsigned long to get a dma address is not enough. (I'm not even going so far that we'll add IOMMU support, but on some architectures we need a place where we can check if a pointer is DMA mappable at all) Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * 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).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
