X86下vxworks的romStart分析：

vxworks 压缩型BOOT的romStart分析：
binArrayStart：压缩的二进制image的起始地址
binArrayEnd：压缩的二进制image的结束地址
压缩的二进制image中没有romInit.o和bootInit.o
将ROM_OFFSET(binArrayStart)开始解压RAM_DST_ADRS地址，即RAM_HIGH_ADRS地址，

然后直接跳转到usrInit().

下面这段拷贝，具体含义是：

/*
     * copy text to uncached locations to avoid problems with
     * copy back caches
     * copy the entire data segment because there is no way to ensure that
     * binArray is the last thing in the data segment because of GP relative
     * addressing
     */

知道可以说一下！呵呵

((FUNCPTR)ROM_OFFSET(copyLongs)) (ROM_TEXT_ADRS, (UINT)romInit,
        ((UINT)binArrayStart - (UINT)romInit)/ sizeof (long));

    ((FUNCPTR)ROM_OFFSET(copyLongs))
           ((UINT *)((UINT)ROM_TEXT_ADRS + ((UINT)BINARRAYEND_ROUNDOFF -
           (UINT)romInit)), (UINT *)BINARRAYEND_ROUNDOFF,
           ((UINT)wrs_kernel_data_end - (UINT)binArrayEnd) / sizeof (long));
