movi比mmc多做了哪些工作

ptn 0 name='bootloader' start=0x0 len=N/A (use hard-coded info. (cmd: movi))
ptn 1 name='kernel' start=N/A len=N/A (use hard-coded info. (cmd: movi))
ptn 2 name='ramdisk' start=N/A len=0x300000(~3072KB) (use hard-coded info. (cmd: movi))

ptn 5 name='cache' start=0x48693000 len=0x1910B800(~410670KB)
ptn 6 name='fat' start=0x6179E800 len=0x8B407000(~2281500KB)
========================================================
调试发现，分区3-6不经过movi命令封装，而是直接mmc命令，疑问：针对0-2三个分区，把mmc封装为movi的目的是什么？movi比mmc额外做了哪些工作？
