| * | ARM: vf610: use strcpy for soc environment variableStefan Agner2016-10-07-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To create the soc environment variable we concatenate two strings on the stack. So far, strcat has been used for the first string as well as for the second string. Since the variable on the stack is not initialized, the first strcat may not start using the first entry in the character array. This then could lead to an buffer overflow on the stack.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the bmode "usb" uses BOOT_CFG1 to 0x01, -which means BOOT_CFG1[7:4] is set to b0000. According to Table 8-7 Boot Device Selection this is NOR/OneNAND and not Reserved. Use 0x10 which leads to b0001, which is a Reserved boot device. With that the SoC reliably falls back to the serial loader.
