2014-12-02Replace hlt with halt()Patrick Georgi
There were instances of unneeded arch/hlt.h includes, various hlt() calls that weren't supposed to exit (but might have) and various forms of endless loops around hlt() calls. All these are sorted out now: unnecessary includes are dropped, hlt() is uniformly replaced with halt() (except in assembly, obviously).

2013-03-22x86: Unify arch/io.h and arch/romcc_io.hStefan Reinauer
Here's the great news: From now on you don't have to worry about hitting the right io.h include anymore. Just forget about romcc_io.h and use io.h instead. This cleanup has a number of advantages, like you don't have to guard device/ includes for SMM and pre RAM anymore. This allows to get rid of a number of ifdefs and will generally make the code more readable and understandable. Potentially in the future some of the code in the io.h __PRE_RAM__ path should move to device.h or other device/ includes instead, but that's another incremental change.

2012-11-14SMM: Avoid use of global variables in SMI handlerDuncan Laurie
Using global variables with the TSEG is a bad idea because they are not relocated properly right now. Instead make the variables static and add accessor functions for the rest of SMM to use. At the same time drop the tcg/smi1 pointers as they are not setup or ever used.

2012-07-26ELOG: Support GSMI in CPT/PPT southbridge SMI handlerDuncan Laurie
In order to support the GSMI interface the SMI handler needs to find and use the state save area from the same CPU that initiated the SMI. In this case it is a synchronous SMI resulting form an IO write to port 0xB2. To find the right CPU state save area iterate over the region until the "IO Misc Info" field reports the expected value and then proceed to use that state save area. This is needed because the coreboot SMI handler only executes on one core, and that core is non-deterministic. It is likely that the core executing the C SMM handler is not the same one that actually did the IO write to 0xB2 and generated the SMI. The GSMI parameter buffer is passed as a pointer to EBX in the tate save area, and the GSMI command is extracted from EAX before it is used as the return value. This interface is tested by enabling CONFIG_GOOGLE_GSMI in the kernel and generating events and verifying that they end up in the event log. 159 | 2012-06-23 16:22:45 | Kernl Event | Clean Shutdown 184 | 2012-06-23 17:14:05 | Kernl Event | Oops 185 | 2012-06-23 17:14:05 | Kernl Event | Panic Change-Id: Ic121ea69e9f50c88467c435e095c3e3629989806 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: http://review.coreboot.org/1317 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.
