Hi Lokesh
I have solved the build errors.
In ptch
v4-0005-configs-am335x_guardian-add-memtest-configs.patch
I moved defined memtest start and end address from guardian
header file to guardian config file
In patch
v4-0011-am335x-guardian-update-swi-logic.patch
added the delay header file
In patch
v4-0016-am335x-guardian-software-update-available-status-.patch
switches add to select default Magic value for guardian and other
board in Kconfig file
I have tested u-boot on guardian target.
because of CI runner space limitations build done up 95% only
and untill that no error found.
Thanks and Regards,
Gireesh Hiremath
