Device tree support and how to enable it for different configs
|
||||
--------------------------------------------------------------
|
||||
Device tree support is available for t1042d4rdb 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="t1042d4rdb" (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-pbl.bin' for other boot.
