2015-04-24fsp: Move fsp to fsp1_0Marc Jones
Prepare for FSP 1.1 integration by moving the FSP to a FSP 1.0 specific directory. See follow-on patches for sharing of common code.

2015-03-18bootstate: use structure pointers for scheduling callbacksAaron Durbin
The GCC 4.9.2 update showed that the boot_state_init_entry structures were being padded and assumed to be aligned in to an increased size. The bootstate scheduler for static entries, boot_state_schedule_static_entries(), was then calculating the wrong values within the array. To fix this just use a pointer to the boot_state_init_entry structure that needs to be scheduled. In addition to the previous issue noted above, the .bs_init section was sitting in the read only portion of the image while the fields within it need to be writable. Also, the boot_state_schedule_static_entries() was using symbol comparison to terminate a loop which in C can lead the compiler to always evaluate the loop at least once since the language spec indicates no 2 symbols can be the same value.

2015-02-09fsp_baytrail: Get FSP reserved memory from the FSP HOB listMartin Roth
Because the pointer to the FSP HOB list is now being saved, we can use that to find the top of usable memory. This eliminates the need to hardcode the size of the FSP reserved memory area. Tested on minnowboard max for baytrail. The HOB structure used does not seem to be present for the rangeley or ivybridge/pantherpoint FSPs. At the very least, the GUID is not documented in the integration guides.

Add a function to retrieve the location of the CAR temporary memory that was saved by the FSP into the HOB structure.

2015-01-06drivers/intel/fsp: split the UEFI HOB functions into hob.cMartin Roth
The FSP uses a lot of UEFI HOB (Hand Off Block) functions for reporting and passing information to coreboot. These seem to me like they should be in their own file, so I'm splitting them out of fsp_util.c. I'll be adding a couple more functions in the next patch. These functions should all be compliant to the Hand Off Block spec.
