关于bootargs 内存参数意思

setenv bootargs 'console=ttyO0,115200n8 rootwait=1 rw ubi.mtd=4,2048 rootfstype=ubifs root=ubi0:rootfs init=/init mem=80M vram=4M notifyk.vpssm3_sva=0xBFD00000 ip=192.168.1.168 eth=00.0C.0C.02.39.6F cmemk.phys_start=0x85000000 cmemk.phys_end=0x89000000 cmemk.allowOverlap=1 earlyprintk'

1,上面的mem=80M表示Linux可以使用的内存有多少,那起始地址在那呢?

2,cmemk.phys_start=0x85000000 cmemk.phys_end=0x89000000  表示什么内存地址阿

3,vram=4M 是指什么内存阿?
