Translate This Thread From English to

my linux-kernel version: 2.4.26
host os: debian
cpu: ppc755
ram disk size:4M
ram size:512M
serial console: 115200
bootroom: build by myself with vxworks.
boadtype: i select bord type as sandpoint(board design by self.but like
sandpoint)

after bootroom load and decompress kernel at phy-address:0x0
jump to 0x00 to linux kernel
but after output Total pages info, it's dead.

modify history:
  arch/ppc/boot/simple/Makefile kernel-boot address linkto 0x1b00000
  arch/ppc/boot/simple/misc-simple.c decompress to 0x00 with size 0x1b00000

  arch/ppc/platform/sandpoint.c  modify memory size query result from
32*1024*1024 as 512*1024*1024

make menuconfig:
  set kernel default param: root=/dev/ram rw console=ttyS0,115200


this fllowing info is output-info on console:
comment:[IIII]*** is info output by myself
        [hack-printk] is hook printk info on console by modify printk() in
kernel/printk.c
