device tree support and how to enable it for different configs
|
||||
--------------------------------------------------------------
|
||||
device tree support is available for t1024rdb 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="t1024rdb" (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.

||||
