How can i fix the BSS size?
Sebastian should look into this but as a quick hint, the symbol marking
bss end sounds like it is after something indicating end of RAM. I have
seen this on other BSPs but the ARM linkcmds is shared, Sebastian did the
magic for that.
You should be able to spot the issue since you have test cases.
