From 3a54318856428cda41c5a45e41c4da727d352bf6 Mon Sep 17 00:00:00 2001 From: Martin Roth Date: Mon, 28 Sep 2015 15:27:24 -0600 Subject: Add EM100 'hyper term' spi console support in ramstage & smm The EM100Pro allows the debug console to be sent over the SPI bus. This is not yet working in romstage due to the use of static variables in the SPI driver code. It is also not working on chipsets that have SPI write buffers of less than 10 characters due to the 9 byte command/header length specified by the EM100 protocol. While this currently works only with the EM100, it seems like it would be useful on any logic analyzer with SPI debug - just filter on command bytes of 0x11.
