We have modified the start.S file for the following #define as our
flash start address is 0xFF000000 according to flash size.

#define CONFIG_SYS_FLASH_BASE		0xf8000000
changed to
# define CONFIG_SYS_FLASH_BASE		0xff000000

We have added only debug statements in board.c. We did not change any
value/variable in this file.

We are using yosemite board configuration files as we derived our
board as per the yosemite board. Please let me know, if there is any
document / README for creating the own config files.

Sure. I will look into it. I will update if there is any luck for me.

The README file which is available in the main u-boot directory says
use CAPITAL letters YOSEMITE only. That is the reason, I used it. I
also saw in the google where they used the CAPITAL letters for
building the u-boot.bin file for their specific board. Please let me
know, If I am wrong or any thing I am missing here.

Thanks and Regards,
