help
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.
