Currently there's one bug in tools/firmware/vmxassist/vmxassist.ld. It intends to put all uninitialized globe variables in object files into between _bbss and _ebss. In head.S, it sets memory between _bbss and _ebss to 0. But for gcc, compiler will put uninitialized globe variables (e.g: int a;) into a section called COMMON, rather than .bss, and linker collects variables in COMMON section of all objects and puts them in .bss. So it results in uninitialized globe variables are behind _ebss, rather than in front of it, which will not be set to 0. This patch fixes it. Thanks, Xiaowei Attachment:
