| * | Introduce non volatile device variablesSascha Hauer2016-07-061-0/+3
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | Non volatile device variables are used to make device parameters persistent. They are like normal non volatile variables, but set the values of the device parameters with the corresponding name. Every nv variable beginning with nv.dev is a non volatile device variable. They have the form nv.dev.<devname>.<paramname> and act on the parameter <paramname> of the device named <devname>. The non volatile device variables are designated for example for video modes, ethernet device ip addresses or mtd partitioning. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* ubiformat: Fix formatting devices with unreadable areasSascha Hauer2016-05-201-2/+7
| | | | | | | | | When parts of a Nand device are not readable due to excessive bit flips we should not bail out with an error as this means we can never repair the device by flashing a fresh image using ubiformat. Instead, treat a failed read as a corrupt block and ignore the read failure. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Our asprintf and vasprintf have different prototypes than the glibc functions.

|/ | | | | | | | | | | | | | | | We have at least two places which convert a string to a boolean type, so create a common function for this. strtobool treats - any positive (nonzero) number as true - "0" as false - "true" (case insensitive) as true - "false" (case insensitive) as false Every other value results in an error and the input *val is not modified. The caller is expected to initialize *val with the correct default before calling strtobool. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

The 20 bytes buffer reserved to store the formatted string "%llu Bytes" is to small: (20 + 6) = 26. Hence, a bigger buffer is reserved to hold this string.

| | | | | | | | | | The decompressors are used both in a regular image and also for image decompression. Both need different malloc implementations. Using malloc/free directly in the decompressor code easily leads to include file conflicts, so use MALLOC/FREE which can be defined correctly for the two different usecases.

| * barebox remote controlSascha Hauer2016-01-181-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds the ability to control barebox over serial lines. The regular console is designed for human input and is unsuitable for controlling barebox from scripts since characters can be lost on both ends, the data stream contains escape sequences and the prompt cannot be easily matched upon. This approach is based on the RATP protocol. RATP packages start with a binary 0x01 which does not occur in normal console data. Whenever a 0x01 character is detected in the console barebox goes into RATP mode. The RATP packets contain a simple structure with a command/respone type and data for that type. Currently defined types are: BB_RATP_TYPE_COMMAND (host->barebox): Execute a command in the shell BB_RATP_TYPE_COMMAND_RETURN (barebox->host) Sends return value of the command back to the host, also means barebox is ready for the next command BB_RATP_TYPE_CONSOLEMSG (barebox->host) Console message from barebox Planned but not yet implemented are: BB_RATP_TYPE_PING (host->barebox) BB_RATP_TYPE_PONG (barebox->host) For testing purposes BB_RATP_TYPE_GETENV (host->barebox) BB_RATP_TYPE_GETENV_RETURN (barebox->host) Get values of environment variables Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Tested-by: Andrey Smirnov <andrew.smirnov@gmail.com>
| * Add Reliable Asynchronous Transfer ProtocolSascha Hauer2016-01-183-0/+1843
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for Reliable Asynchronous Transfer Protocol (RATP) as described in RFC916. Communication over RS232 is often unreliable as characters are lost or misinterpreted. This protocol allows for a reliable packet based communication over serial lines. The implementation simply follows the state machine described in the RFC text with one exception. RFC916 uses a plain checksum for the transferred data. We decided to use CRC16 for greater robustness. Since this is the only RFC916 implementation we currently know of interoperability with other implementations should not matter.

* / bootstrap: Boot barebox with kernel calling conventionTrent Piepho2015-12-141-2/+2
|/ | | | | | | | | | | | | | | | | | | | | | | | In commit 8e3ddc13eb8239177ed20f119e3a3d02518b941d the bootm code was changed to boot barebox using the same calling convention as the kernel. Which on ARM is to pass three arguments which are zero, an architecture code, and a params pointer. A 2nd stage barebox can be booted using lib/bootstrap, which is different code from bootm. This code just leaves garbage in the first three parameters and so doesn't follow the convention. Change it to be compatible with the ARM kernel booting convention. This just sends a zero for the architecture, since the code for architectures depends on boot[zmu] and something using bootstrap wouldn't have those too. And it just passes NULL for the params since we don't have a way to pass a device tree from the preloader. All users of bootstrap are ARM based, but the code is in lib so a non-ARM board might someday make use of it. If the current code would work for them, then the change here will be ok too.

* | fbconsole: register fonts dynamicallySascha Hauer2015-11-134-33/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of having a fixed array of fonts register the fonts dynamically. This allows easier adding of fonts to the tree since only one file per font has to be added and no other files modified. Currently we have to register the fonts very early before the first framebuffer is registered. This is because of our limited dev_add_param_enum() which wants to know the number of elements when called, so we can't add elements once after we've called dev_add_param_enum(). Maybe a dev_add_param_array() has to be created whithout this limitation, but that's left for a future exercise. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
