Hi Sandeep,

Turning on SOC_SAMA5* for all at91, including legacy, is likely not what you want. > 1.

(i.e > for example, legacy uses armv5 instructions and sama5 needs arm v7 > instructions) 'CONFIG_SUBTARGET' doesn't exist use 'CONFIG_TARGET=subtarget' where the subtarget to be modified has been selected using menuconfig. With the above option dont replace 'subtarget' with the subtarget name.
