Help text

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.
