After moving the driver code out of the bsp directory all the code that remains is common to all x86 platforms move the code and assocoated config variables to arch/x86. Change-Id: I76617070bb165fd157f0c3a127f1b9829b86c283 Signed-off-by: Dirk Brandewie <dirk.j.brandewie@intel.com>

* _SysFatalErrorHandler - fatal error handler
|
|
*
|
|
* This routine implements the corrective action to be taken when the system
|
|
* detects a fatal error.
|
|
*
|
|
* This sample implementation attempts to abort the current context and allow
|
|
* the system to continue executing, which may permit the system to continue
|
|
* functioning with degraded capabilities.
|
|
*
|
|
* System designers may wish to enhance or substitute this sample
|
|
* implementation to take other actions, such as logging error (or debug)
|
|
* information to a persistent repository and/or rebooting the system.
|
|
*
|
|
* RETURNS: This function does not return.
