kernel_parameter patch 的问题

thefat

俺下了那个 kernel_paramter 的 patch, 看 code 还是挺美好的。不过到现在没用成。

俺滴 conf 长这样：

#skyeye config file sample
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=./romfs.img
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
net: type=cs8900a, base=0xfffa0000, size=0x20,int=17, mac=0:4:3:2:1:f, ethmod=tuntap, hostip=10.0.0.1
kernel_parameters: default_cmdline="root=/dev/rom0 ether=17,0xfffa0000,eth0", addr=0x00000100
#end

显然我在 atmel 的 arch.c 里加了一行：
       BOOT_PARAMS(0x00000100)

跟了 skyeye 的 code, 挺美好滴。 ATAG_CMDLINE 设了，r2 也设了。

可 gdb 跟 linux 一看就全不是这么回事了。r2 显然没用，start_kernel 前就给干掉了；好在 BOOT_PARAMS(0x00000100) 在 setup_arch 里找到了 tag，可跟到 parse_tag 里一看全是 ATAG_CORE, 就没有看到 ATAG_CMDLINE, 而且 ATAG_CORE 显然也还有问题，在 setup_arch 的 paging_init 就 hang 了。

麻烦写这个 patch 的兄弟出来吱一声，俺就不乱改了。

Please send the post to [email protected] . All the issue related developement should be sent to maillist. For there is some nonchinese developer.  And the patch is committed just by a non-chinese guy.So maybe he can not come here to answer you

ok, i'll do it.
i walked around it by disabled the memory bank tags in kernel parameters. and it works now.
