+         If you want to add compressed kernel support to a new board, and the
+         board supports uart16550 compatible serial port, please select
+         SYS_SUPPORTS_ZBOOT_UART16550 for your board and enable this option to
+         debug it.
+
+         If your board doesn't support uart16550 compatible serial port, you
+         can try to select SYS_SUPPORTS_ZBOOT and use the other methods to
+         debug it. for example, add a new serial port support just as
+         arch/mips/boot/compressed/uart-16550.c does.
+
+         After the compressed kernel support works, please disable this option
+         to reduce the kernel image size and speed up the booting procedure a
+         little.
