pxa270系统移植，求救

Question

最近搞了一下eeliod的linux2.6.38移植，把XSBASE270_EDR平台加了进去，其中MACHINE_START模块在下面

#if defined(CONFIG_ARCH_XSBASE270_EDR)
MACHINE_START(XSBASE270, "51Board XSBase270-EDR Development Platform "
#elif defined(CONFIG_ARCH_XSBASE270_DVK)
MACHINE_START(XSBASE270, "51Board XSBAse270-DVK Development Platform "
#endif
        .phys_io        = 0x40000000,
        .boot_params        = 0xA0000100,        /* BLOB boot parameter setting */
        .io_pg_offst        = (io_p2v(0x40000000) >> 1 & 0xfffc,  //  BOOT_MEM(0xA0000000, 0x40000000, io_p2v(0x40000000))
        .map_io                = xsbase27x_map_io,
        .init_irq        = xsbase27x_init_irq,
        //.fixup                = fixup_xsbase27x,
        .timer                = &pxa_timer,
        .init_machine        = xsbase27x_init,  //FIXUP(fixup_xsbase27x)  MAINTAINER("51Board Inc."
MACHINE_END

booting the kernel之后没有反映了，终于查到了一个办法去除printk缓冲区，是这样的：

说明start_kernel已经调用，MMU也已经开启，这里在初始化页表之后进行首次malloc，但是就出错了这是怎么回事？我在启动参数那里添加了MEM=64M。

万望帮帮忙，谢谢！

PXA270比较老了，N年前玩的，现在都忘记了
