commit f0278edfde21bd854327a5342acfe66d655092ba Author: Kyösti Mälkki kyosti.malkki@gmail.com Date: Sat Jul 6 11:56:49 2013 +0300
usbdebug: Move ehci_debug_info allocation
Move ehci_debug_info allocation from console to lib, as console code was only built for ramstage.
Implement dbgp_ehci_info() to return the EHCI context. Alread alias this as dbgp_console_input() and _output() to return the console stream context later on.
