Previously Haswell used a romcc bootblock and starting verstage in romstage was madatory but with C_ENVIRONMENT_BOOTBLOCK it is also possible to have a separate verstage. This selects using a separate verstage by default but still keeps the option around to use verstage in romstage. Also make sure mrc.bin is only added to the COREBOOT fmap region as it requires to be run at a specific offset. This means that coreboot will have to jump from a RW region to the RO region for that binary and back to that RW region after that binary is done initializing the memory.

2013-03-19haswell: Parallel AP bringupAaron Durbin
This patch parallelizes the AP startup for Haswell-based devices. It does not touch the generic secondary startup code. Instead it provides its own MP support matching up with the Haswell BWG. It seemed to be too much trouble to support the old startup way and this new way. Because of that parallel loading is the only thing supported. A couple of things to note: 1. Micrcode needs to be loaded twice. Once before MTRR and caching is enabled. And a second time after SMM relocation. 2. The sipi_vector is entirely self-contained. Once it is loaded and written back to RAM the APs do not access memory outside of the sipi_vector load location until a sync up in ramstage. 3. SMM relocation is kicked off by an IPI to self w/ SMI set as the destination mode. The following are timings from cbmem with dev mode disabled and recovery mode enabled to boot directly into the kernel. This was done on the baskingridge CRB with a 4-core 8-thread CPU and 2 DIMMs 1GiB each. The kernel has console enabled on the serial port. Entry 70 is the device initialization, and that is where the APs are brought up. With these two examples it looks to shave off ~200 ms of boot time.

2013-03-18haswell: adjust CAR usageAaron Durbin
It was found that the Haswell reference code was smashing through the stack into the reference code's heap implementation. The reason for this is because our current CAR allocation is too small. Moreover there are quite a few things to coordinate between 2 code bases to get correct. This commit separates the CAR into 2 parts: 1. MRC CAR usage. 2. Coreboot CAR usage. Pointers from one region can be passed between the 2 modules, but one should not be able to affect the others as checking has been put into place in both modules. The CAR size has effectively been doubled from 0x20000 (128 KiB) to 0x40000 (256KiB). Not all of that increase was needed, but enforcing a power of 2 size only utilizes 1 MTRR. Old CAR layout with a single contiguous stack with the region starting at CONFIG_DCACHE_RAM_BASE: +---------------------------------------+ Offset CONFIG_DCACHE_RAM_SIZE | MRC global variables | | CONFIG_DCACHE_RAM_MRC_VAR_SIZE bytes | +---------------------------------------+ | ROM stage stack | | | | | +---------------------------------------+ | MRC Heap 30000 bytes | +---------------------------------------+ | ROM stage console | | CONFIG_CONSOLE_CAR_BUFFER_SIZE bytes | +---------------------------------------+ | ROM stage CAR_GLOBAL variables | +---------------------------------------+ Offset 0 There was some hard coded offsets in the reference code wrapper to start the heap past the console buffer. Even with this commit the console can smash into the following region depending on what size CONFIG_CONSOLE_CAR_BUFFER_SIZE is. As noted above This change splits the CAR region into 2 parts starting at CONFIG_DCACHE_RAM_BASE: +---------------------------------------+ | MRC Region | | CONFIG_DCACHE_RAM_MRC_VAR_SIZE bytes | +---------------------------------------+ Offset CONFIG_DCACHE_RAM_SIZE | ROM stage stack | | | | | +---------------------------------------+ | ROM stage console | | CONFIG_CONSOLE_CAR_BUFFER_SIZE bytes | +---------------------------------------+ | ROM stage CAR_GLOBAL variables | +---------------------------------------+ Offset 0 Another variable was add, CONFIG_DCACHE_RAM_ROMSTAGE_STACK_SIZE, which represents the expected stack usage for the romstage. A marker is checked at the base of the stack to determine if either the stack was smashed or the console encroached on the stack.

2013-03-18haswell: Use SMM ModulesAaron Durbin
This commit adds support for using the SMM modules for haswell-based boards. The SMI handling was also refactored to put the relocation handler and permanent SMM handler loading in the cpu directory. All tseg adjustment support is dropped by relying on the SMM module support to perform the necessary relocations.

2013-03-14haswell: Add initial support for Haswell platformsAaron Durbin
The Haswell parts use a PCH code named Lynx Point (Series 8). Therefore, the southbridge support is included as well. The basis for this code is the Sandybridge code. Management Engine, IRQ routing, and ACPI still requires more attention, but this is a good starting point. This code partially gets up through the romstage just before training memory on a Haswell reference board.
