[U-Boot] [PATCHv2 06/14] powerpc: Enable device tree support for P1020RDB

Hou Zhiqiang Zhiqiang.Hou at nxp.com
Tue Aug 20 09:35:28 UTC 2019


Add device tree for P1020RDB boards and enable CONFIG_OF_CONTROL
so that device tree can be compiled.
Update board README for device tree usage.

+Device tree support and how to enable it for different configs
+--------------------------------------------------------------
+Device tree support is available for p1020rdb for below mentioned boot,
+1. NOR Boot
+2. NAND Boot
+3. SD Boot
+4. SPIFLASH Boot
+
+To enable device tree support for other boot, below configs need to be
+enabled in relative defconfig file,
+1. CONFIG_DEFAULT_DEVICE_TREE="p1020rdb" (Change default device tree name if required)
+2. CONFIG_OF_CONTROL
+3. CONFIG_MPC85XX_HAVE_RESET_VECTOR if reset vector is located at
+   CONFIG_RESET_VECTOR_ADDRESS - 0xffc
+
+If device tree support is enabled in defconfig,
+1. use 'u-boot-with-dtb.bin' for NOR boot.
+2. use 'u-boot-with-spl.bin' for other boot.
