| * dm: Use an allocated array for run-time device infoSimon Glass2020-10-291-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At present we update the driver_info struct with a pointer to the device that it created (i.e. caused to be bound). This works fine when U-Boot SPL is stored in read-write memory. But on some platforms, such as Intel Apollo Lake, it is not possible to update the data memory. In any case, it is bad form to put this information in a structure that is in the data region, since it expands the size of the binary. Create a new driver_rt structure which holds runtime information about drivers. Update the code to store the device pointer in this instead. Also update the test check that this works.

| | | | | | | | | | | | | | | | Some drivers use macro pr_cont() for continuing a message sent via printk. Hence if we want to convert printk messaging to using the logging system, we must support continuation of log messages too. As pr_cont() does not provide a message level we need a means of remembering the last log level. With the patch a pseudo log level LOGL_CONT as well as a pseudo log category LOGC_CONT are introduced. Using these results in the application of the same log level and category as in the previous log message.

* watchdog: Implement generic watchdog_reset() versionStefan Roese2019-04-261-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch tries to implement a generic watchdog_reset() function that can be used by all boards that want to service the watchdog device in U-Boot. This watchdog servicing is enabled via CONFIG_WATCHDOG. Without this approach, new boards or platforms needed to implement a board specific version of this functionality, mostly copy'ing the same code over and over again into their board or platforms code base. With this new generic function, the scattered other functions are now removed to be replaced by the generic one. The new version also enables the configuration of the watchdog timeout via the DT "timeout-sec" property (if enabled via CONFIG_OF_CONTROL). This patch also adds a new flag to the GD flags, to flag that the watchdog is ready to use and adds the pointer to the watchdog device to the GD. This enables us to remove the global "watchdog_dev" variable, which was prone to cause problems because of its potentially very early use in watchdog_reset(), even before the BSS is cleared.

| | | | | | | | | | | | | | | | | | | | | | | | Testing has shown that the current DM implementation of a platform / board specific translation offset, as its needed for the SPL on MVEBU platforms is buggy. The translation offset is confingured too late, after the driver bind functions are run. This may result in incorrect address translations. With the current implementation its not possible to configure the offset earlier, as the DM code has not run at all. This patch now removed the set_/get_translation_offset() calls and moves the translation offset into the GD variable translation_offset. This variable will get used when CONFIG_TRANSLATION_OFFSET is enabled. This option is enabled only for MVEBU on ARM32 platforms, where its currenty needed and configured in the SPL.

| | | | | | | | | | | | | | | In some cases it may be useful to be able to change the fdt we have been using and use another one instead. For example, the TI platforms uses an EEPROM to store board information and, based on the type of board, different dtbs are used by the SPL. When DM_I2C is used, a first dtb must be used before the I2C is initialized and only then the final dtb can be selected. To speed up the process and reduce memory usage, introduce a new function fdtdec_setup_best_match() that re-use the DTBs loaded in memory by fdtdec_setup() to select the best match.
