2019-07-11SPL: Default to disabling legacy image support when using FITTom Rini
When we have a FIT image being used by SPL by default that means the most common case is that we'll never run into a legacy image. Disable legacy image support by default in that case to reclaim space. Signed-off-by: Tom Rini <trini@konsulko.com>
2019-07-11configs: Rename CONFIG_IMAGE_FORMAT_LEGACY to CONFIG_LEGACY_IMAGE_FORMATTom Rini
The name CONFIG_LEGACY_IMAGE_FORMAT reads slightly better along with allowing us to avoid a rather nasty Kbuild/Kconfig issue down the line with CONFIG_IS_ENABLED(IMAGE_FORMAT_LEGACY). In a few places outside of cmd/ switch to using CONFIG_IS_ENABLED() to test what is set. Signed-off-by: Tom Rini <trini@konsulko.com>

2019-07-09ubispl: add support for loading volumes by nameHamish Guthrie
The motivation is to use the UBI atomic volume rename functionality to allow double copy software updates on UBI. To that end the SPL is configured to always load the same volume name (e.g. "u-boot"), whereas a software updater always installs into the secondary volume "u-boot_r". After successful installation, these two volume names are switched. This extension is protected by #ifdefs as it will somewhat slow down loading of volumes by id. This is because the code needs to disable the optimization of ignoring all volume ids which are not to-be-loaded, since these can only be resolved after attaching. This adds two vtbl related functions from Linux, which are taken from the same kernel version as the current main U-Boot UBI code (Linux 4.2 64291f7db5bd8).

2019-07-07board_r: move initr_watchdog to be called after initr_serialWeijie Gao
The initr_watchdog is currently placed before initr_serial. The initr_watchdog calls printf and printf finally calls ops->putc of a serial driver. However, gd->cur_serial_dev points to a udevice allocated in board_f. The gd->cur_serial_dev->driver->ops->putc points the the code region before relocation. Some serial drivers call WATCHDOG_RESET() in ops->putc. When DM is enabled for watchdog, watchdog_reset() is called. watchdog_reset() calls get_timer to get current timer. On some platforms the timer driver is also a DM driver. initr_watchdog is placed right after initr_dm, which means the timer driver hasn't been initialized. So dm_timer_init() is called. To create a new udevice, calloc is called. However start from ops->putc, u-boot execution flow is redirected into the memory region before relocation (board_f). In board_f, dlmalloc hasn't been initialized. The call to calloc will fail, and this will cause DM to print out an error message, and it will call printf again, causing recursive error outputs. This patch places initr_watchdog after initr_serial to solve this issue.

By default the configuration of the PMC is to have an external crystal connected that requires driving on both XIN and XOUT pins. The bypass configuration means that only XIN will be used, the SoC will not do any driving, and the XIN needs to be provided with a proper signal. This is the MOSCXTBY bit in the PMC main clock generator register. The SPL needs to properly initialize the PMC registers before switching to external clock signal and raising the clock to the cruise speed. Also created Kconfig for this specific configuration.

2019-05-20splash: Load internal and external data from FITLeo Ruan
The FIT image could contain the splash data in 3 different structure: - The splash data is embedded in FIT image (internal) In this case, the property 'data' presents in FIT image header. And internal information 'start' and 'end' represent the location and size of splash data inside of FIT image. - The splash data is external with absolute position in FIT image This case is made by 'mkimage -p [pos]'. The splash data is stored at the absolute position. Instead the property 'data', the properties 'data-position' and 'data-size' are used to specify the location and size of the splash data. - the splash data is external with relative offset in FIT image This case is made by 'mkimage -E'. The splash data is placed after the FIT image header with 4 byte alignment. Instead the property 'data', the properties 'data-offset' and 'data-size' are used to specify the location and size of the splash data. Currently, the splash only support to load external data with relative offset from FIT image.

2019-05-20splash: Use splashfile instead of location->nameLeo Ruan
The splash image could be loaded from different sources (e.g. sf, mmc) with different formats (e.g. raw, file-system). These sources are structured by a board dependent object 'splash_location'. To decide where is the splash image loaded, following environment variables are used to select the splash source and file: - 'splashsource' is used to select the splash source by setting its value to specified name of splash location. - 'splashfile' specify the name of splash image file But, when loads the splash image from FIT, the name of splash image within FIT is specified by splash location name. Due to the splash location name is already used for the splash source, its name may conflicts with the name of splash image. To solve the conflict, the environment variable 'splashfile' is used to specify the splash image in FIT, and keeps the splash location name for the splash source.

2019-04-26watchdog: Implement generic watchdog_reset() versionStefan Roese
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.

2019-04-23sandbox: Improve debugging in initcall_run_list()Simon Glass
At present if one of the initcalls fails on sandbox the address printing is not help, e.g.: initcall sequence 0000557678967c80 failed at call 00005576709dfe1f (err=-96) This is because U-Boot gets relocated high into memory and the relocation offset (gd->reloc_off) does not work correctly for sandbox. Add support for finding the base address of the text region (at least on Linux) and use that to set the relocation offset. This makes the output better: initcall sequence 0000560775957c80 failed at call 0000000000048134 (err=-96) Then you use can use grep to see which init call failed, e.g.: $ grep 0000000000048134 u-boot.map stdio_add_devices Of course another option is to run it with a debugger such as gdb: $ gdb u-boot ...

Our platform doesn't store the DTB into the Android image second area, but rather copies the DTB to RAM from a dedicated dtb.img partition [0], prior to booting the Android image by calling bootm. Similar to [1], we find it useful to just call 'bootm' and have the right DTB being passed to OS (assuming its address has been previously stored in 'fdtaddr' by calling `fdt addr <dtb-addr>`). Booting Android with DTB from 'fdtaddr' will only occur if: - No DTB is embedded in the second area of Android image - 'fdtaddr' points to a valid DTB in RAM [0] https://source.android.com/devices/architecture/dto/partitions [1] https://patchwork.ozlabs.org/patch/1046652/ ("Support boot Android image without address on bootm command") Signed-off-by: Eugeniu Rosca <erosca@de.adit-jv.com> Reviewed-by: Simon Glass <sjg@chromium.org>

Prepare for booting Android images which lack any DTB in the second area by using 'fdtaddr' environment variable as source/address of FDT. No functional/behavioral change expected in this patch. Signed-off-by: Eugeniu Rosca <erosca@de.adit-jv.com> Reviewed-by: Simon Glass <sjg@chromium.org>
