There will clear the BSS in the function clear_bss(), the reset address of the BSS started from the __bss_start, and increased by four-byte increments, finally stoped depending on the address is equal to the _bss_end. If the end address __bss_end is not alignment to 4byte, it will be an infinite loop.
- The reset action stoped depending on the reset address is greater
than or equal the end address of the BSS. 2. The end address of the BSS should be 4byte aligned. Because the reset unit is 4 Bytes.
Should we add explicit alignment of the BSS start as well? [Zhang Ying] That is better. I can add.
