U-Boot won't use the interrupt properties anyway. It's just to be consistent with the Linux device tree.

The variable 'mode' contains only the configuration whether the gpio is currently an input or an output. * The correct bitmasks for the input and output value are PAD_CFG0_RX_STATE and PAD_CFG0_TX_STATE.

2020-02-04watchdog: omap_wdt: Fix WDT reloadingMarek Vasut
The watchdog timer value was never updated in the hardware by this driver, so the watchdog triggered on some random stale value that was left in the hardware. The TI SPRUH37C says, quote: 20.4.3.9 Modifying Timer Count/Load Values and Prescaler Setting ... After a write access, the load register value and prescaler ratio registers are updated immediately, but new values are considered only after the next consecutive counter overflow or after a new trigger command (the WDT_WTGR register). This means at least one trigger must happen. The driver probably depended on someone calling it's .reset() callback, however that is not guaranteed e.g. if the WDT operates without servicing. Add this missing trigger.

2020-02-04cmd: abootimg: Add abootimg commandSam Protsenko
This command can be used to extract fields and image payloads from Android Boot Image. It can be used for example to implement boot flow where dtb is taken from boot.img (as v2 incorporated dtb inside of boot.img). Using this command, one can obtain needed dtb blob from boot.img in scripting manner, and then apply needed dtbo's (from "dtbo" partition) on top of that, providing then the resulting image to bootm command in order to boot the Android. Also right now this command has the sub-command to get an address and size of recovery dtbo from recovery image (for non-A/B devices only, see [1,2] for details). It can be tested like this: => mmc dev 1 => part start mmc 1 boot_a boot_start => part size mmc 1 boot_a boot_size => mmc read $loadaddr $boot_start $boot_size => abootimg get ver => abootimg dump dtb [1] https://source.android.com/devices/bootloader/boot-image-header [2] https://source.android.com/devices/architecture/dto/partitions Signed-off-by: Sam Protsenko <joe.skb7@gmail.com> Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com>
2020-02-04image: android: Add routine to get dtbo paramsSam Protsenko
Android Boot Image v1 adds "Recovery DTB" field in image header and associate payload in boot image itself [1]. Payload should be in Android DTB/DTBO format [2]. That "Recovery DTB" area should be only populated for non-A/B devices, and only in recovery image. Add function to get an address and size of that payload. That function can be further used e.g. in 'abootimg' command to provide the user a way to get the address of recovery dtbo from U-Boot shell, which can be further parsed using 'adtimg' command.

2020-02-04image: android: Add functions for handling dtb fieldSam Protsenko
Android Boot Image v2 adds "DTB" payload (and corresponding field in the image header). Provide functions for its handling: - android_image_get_dtb_by_index(): Obtain DTB blob from "DTB" part of boot image, by blob's index - android_image_print_dtb_contents(): Iterate over all DTB blobs in "DTB" part of boot image and print those blobs info "DTB" payload might be in one of the following formats: 1. concatenated DTB blobs 2. Android DTBO format The latter requires "android-image-dt.c" functionality, so this commit selects that file for building for CONFIG_ANDROID_BOOT_IMAGE option. Right now this new functionality isn't used, but it can be used further. As it's required to apply some specific dtbo blob(s) from "dtbo" partition, we can't automate this process inside of "bootm" command. But we can do next: - come up with some new command like "abootimg" to extract dtb blob from boot image (using functions from this patch) - extract desired dtbo blobs from "dtbo" partition using "adtimg" command - merge dtbo blobs into dtb blob using "fdt apply" command - pass resulting dtb blob into bootm command in order to boot the Android kernel with Android ramdisk from boot image Signed-off-by: Sam Protsenko <joe.skb7@gmail.com> Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com>
