From: Ron Madrid ron_madrid@sbcglobal.net Subject: [PATCH] Create configuration option for restricted ns16550 functions To: u-boot@lists.denx.de Cc: "Ron Madrid" ron_madrid@sbcglobal.net Date: Friday, January 30, 2009, 3:45 PM This patch will create a configuration option for a minimum configuration for the ns16550 serial driver at drivers/serial/ns16550.c which will exclude all functions with exception of NS16550_putc and NS16550_init. This will be used primarily to save space and remove unused code from builds in which space is limited.

Did this get looked at? I don't remember seeing anything about it. If it is still being looked at, just let me know.
Thanks,
