Aswath Govindraju June 1, 2021, 11:21 a.m. UTC 
Currently the config options CONFIG_SYS_DFU_DATA_BUF_SIZE and
CONFIG_SYS_DFU_MAX_FILE_SIZE are being set in include/configs/<board>.h
files and also in <board_name>_defconfig files without a Kconfig option. It
is easier for users to set these configs in defconfig files than in config
header files as they are a part of the source code.

Add Kconfig symbols, and update the defconfigs by using tools/moveconfig.py
script.

I saw that this patch is delegated to Tom Rini in patchwork page but I
did not add him in the cc-list. So, I added him now.

Hi Tom,

May I know if this patch is good to be picked?

Thanks,
Aswath
