scs: re-init return variable to fail code, disable optimization [1/1]
PD#RSP-6589
Problem:
Need to prevent glitch attack skipping a statement and using
previously assigned hardened successful return value from being
used.
Finding ID 24
Solution:
re-initialize to failure and disable compiler optimization
Verify:
./build.sh s6 with and without change
ls bl32.* before:
-rw-r--r-- 1 649328 ./bl32.bin
-rw-r--r-- 1 649840 ./bl32.img
after
-rw-r--r-- 1 653424 ./bl32.bin
-rw-r--r-- 1 653936 ./bl32.img
