we are designing an switch with P1022 chip,and we plan to boot from SPI flash.So when build boot,we use commands like this:
make ARCH=powerpc CROSS_COMPILE=powerpc-fsl-linux-gnuspe- P1022DS_SPIFLASH_config
make ARCH=powerpc CROSS_COMPILE=powerpc-fsl-linux-gnuspe-
Then u-boot.bin will be built in the root dir.But after bure it to spi flash,and power on ,we found that cpu can't boot from spi flash.After searching from the internet,we got to know that PBI and RCW will be needed together with u-boot.bin to generate the final file.So could you please kindly attach the boot_format and the related config_sram.dat file for us?
Or please tell me how to get the tools and the config files ,thanks a lot .
Appreciate for your help.
