请教一个问题

调试uclinux的时候,我看at91的例子是这样子设置的
cpu: arm7tdmi
mach: at91
mem_bank: map=M, type=RW, addr=0x00000000, size=0x00004000
mem_bank: map=M, type=RW, addr=0x01000000, size=0x00400000
mem_bank: map=M, type=R,  addr=0x01400000, size=0x00400000, file=./boot.rom
mem_bank: map=M, type=RW, addr=0x02000000, size=0x00400000
mem_bank: map=M, type=RW, addr=0x02400000, size=0x00008000
mem_bank: map=M, type=RW, addr=0x04000000, size=0x00400000
mem_bank: map=I, type=RW, addr=0xf0000000, size=0x10000000

然后还需要打命令,skyeye linux
这里boot.rom是烧写在flash里面的内核映象对吧,但是,为什么命令需要加上linux呢?
还有一种是不用linux的
mem_bank: map=M, type=RW, addr=0x00000000, size=0x00004000
mem_bank: map=M, type=RW, addr=0x01000000, size=0x00400000, file=./image.bin, boot=yes
mem_bank: map=M, type=R,  addr=0x01400000, size=0x00400000, file=./boot.rom
mem_bank: map=M, type=RW, addr=0x02000000, size=0x00400000
mem_bank: map=M, type=RW, addr=0x02400000, size=0x00008000
mem_bank: map=M, type=RW, addr=0x04000000, size=0x00400000
mem_bank: map=I, type=RW, addr=0xf0000000, size=0x10000000
#set nic info state=on/off  mac=xxxxxxx  ethmod=tuntap/vnet hostip=dd.dd.dd.dd
net: state=on, mac=0:4:3:2:1:f, ethmod=tuntap, hostip=10.0.0.1
#log: logon=1, logfile=/tmp/test.log, start=100000, end=1000000
log: logon=0, logfile=/tmp/test.log, start=3200000, end=3330000

请问这两中做法的区别在哪里?具体的意义是怎么样的?

In the 1st case, skyeye load the elf file "linux"
in 2nd case, image.bin is a binary image coverted from elf file
