*	LZMA buffer note:

*	1, LZMA offset depends on the memory layout:
*	for FOTA, we need to reserve 32MB for FBF, if FOTA FBF is larger than 32MB, fix me!
*	for boot, we only need to reserve 1MB for OBM itself.
*
*	2, LZMA internal buffer size is 0x00007cd8, so, we need to reserve 32KB;
*
*	3, for decompress, we better reserve 6MB for decompress just in case.
