+virt platform mrom
+Description of problem:
+qemu-system-riscv32 to emulated the lowrisc ibex simple system hello, when debug with riscv32-unknown-elf-gdb, there kept logging "Invalid read at addr 0x0, size 2, region '(null)', reason: rejected".  
+I saw qemu virt platform codes related to this error, it load reset_vec to 0x1000 called VIRT_MROM. I still not understand why this error happens.
+Steps to reproduce:
+1.git clone https://github.com/lowRISC/ibex.git  
+2.cd ibex  
+3.make -C examples/sw/simple_system/hello_test  
+4.using the qemu command line above  
+5.`riscv32-unknown-elf-gdb -ex target remote localhost:1234 examples/sw/simple_system/hello_test` in another terminal, type bt, the error happens.
