您好：
目前AM2634 QSPI SBL默认的地址分配如下：
R5F_VECS : ORIGIN = 0x70000000 , LENGTH = 0x00000100
R5F_TCMA : ORIGIN = 0x00000100 , LENGTH = 0x00007F00
R5F_TCMB0: ORIGIN = 0x41010000 , LENGTH = 0x00008000
MSRAM_VECS: ORIGIN = 0x70002000 , LENGTH = 0x00000100
MSRAM_0 : ORIGIN = 0x70002100 , LENGTH = 0x40000 - 0x2100
请问能否扩大QSPI SBL占用的地址空间，例如将MSRAM_0 设置如下：
MSRAM_0 : ORIGIN = 0x70002100 , LENGTH = 0x60000 - 0x2100
