First we need to enable write into "ROM" and we do it with "preloadexec" command:

mdb -dll=opxdarc.so -OK -preloadexec="eval *(int*)0xf0001000=0" u-boot

To run glibc test-suite on target without native toolchain we need to have the following 2 requirements:

1. Host executes tests on target via SSH so we need to have SSH server up and running on target. Moreover we need to either enable paswordless login via SSH or install user's SSH key on target so that execution scripts may connect to target via SSH without asking user for entering pasword all the time (there're 5k+ tests).

2. Host's filesystem must be accessible from target. Moreover paths must match exactly on both devices (i.e. "/home/username/glibc-testsuite" in both cases must be available and contain exectly the same data) because tests are being built on the fly and immediately get executed via SSH. Thus we need to mount host's filesystem with glibc testsuite on target.
