[U-Boot-Users] gdb

Hi My working target is the arm926ejs based platform. we want to port the gdb-stub to the u-boot. therefore two console port should be used, one is for host teminal program , another is for the host gdb debugger. right now the serial driver in our platform is polling based. Is there anybody kindly telling me how to initialize the two consoles or any material I can refer to and is it possible to achieve to port gdb-stub into the u-boot with such the polling based serial driver.

Best Regards
