3 The chosen node does not represent a real device, but serves as a place
4 for passing data like which serial device to used to print the logs etc
9 Device trees may specify the device to be used for boot console output
10 with a stdout-path property under /chosen.
16 stdout-path = "/serial@f00:115200";
20 compatible = "vendor,some-uart";
27 In a system there are multiple timers, specify which timer to be used
28 as the tick-timer. Earlier it was hardcoded in the timer driver now
29 since device tree has all the timer nodes. Specify which timer to be
36 tick-timer = "/timer2@f00";
40 compatible = "vendor,some-timer";
45 u-boot,spl-boot-order property
46 ------------------------------
48 In a system using an SPL stage and having multiple boot sources
49 (e.g. SPI NOR flash, on-board eMMC and a removable SD-card), the boot
50 device may be probed by reading the image and verifying an image
53 If the SPL is configured through the device-tree, the boot-order can
54 be configured with the spl-boot-order property under the /chosen node.
55 Each list element of the property should specify a device to be probed
56 in the order they are listed: references (i.e. implicit paths), a full
57 path or an alias is expected for each entry.
63 u-boot,spl-boot-order = &sdmmc, "/sdhci@fe330000";
