linux xlnx:内核在注册SWP/SWPB仿真处理程序时挂起

我正试图在SD卡上获得一个持久分发（Linaro），并在ZedBoard上运行。我从LinuxXLNX源代码构建内核，在启动过程中遇到了许多问题。我已经设法克服了在启动时遇到的大多数内核挂起问题，但我仍停留在“注册SWP/SWPB仿真处理程序”上

我注意到.config文件“config_SWP_EMULATE=y”中有一个选项，但即使我把它注释掉（老实说，我不知道我是否应该这样做），当我用“make UIMAGE_LOADADDR=0x8000 UIMAGE”重新构建内核时，这一行也会在.config文件中重新启用，无论出于什么原因，问题仍然存在

原始配置是使用“make xilinx_zynq_defconfig”创建的。然后，我使用“makemenuconfig”在内核hacking菜单中启用早期打印和低级调试（在UART1上显示输出）。从那里开始，每当内核在某个点卡住时，我都直接编辑.config文件。迄今为止，“xilinx_zynq_defconfig”的显著变化是：

CONFIG_DEBUG_LL=y
CONFIG_DEBUG_ZYNQ_UART1=y
CONFIG_EARLY_PRINTK=y
# CONFIG_SERIAL_XILINX_PS_UART is not set
# CONFIG_RTC_HCTOSYS is not set
CONFIG_ARM_THUMB=y
CONFIG_ARM_THUMBEE=y

如有任何关于如何克服这一问题的建议，将不胜感激。提前感谢：）
