To move 3rdparty to 3rdparty/blobs (ie. below itself from git's broken perspective), we need to work around it - since some git implementations don't like the direct approach.

Currently `IFD_BIN_PATH` is shown twice. Commit 5218e616 (intel/lynxpoint: Allow building without IFD (descripter.bin)) [1] accidentally added the option another time. So fix up the commit and remove one of the two options `IFD_BIN_PATH`. Keep the one which depends on `!HAVE_IFD_BIN` and is around the IFD options.

2014-07-04intel/lynxpoint: Make inclusion of Intel ME optionalPaul Menzel
Current build configuration always wants to include an Intel Management Engine (ME) firmware (`me.bin`) on Intel Lynx Point systems. However, we can have a working coreboot without it, as long as the factory delivered ME firmware is kept untouched in the flash ROM. So let the user decide if a ME firmware will be included in the build by introducing the Kconfig option `HAVE_ME_BIN`. The same was done in commit 99fd30e4 (sandybridge: Make inclusion of me.bin optional) [1] for Intel Sandy Bridge (BD82x6x).

2014-07-04intel/lynxpoint: Allow building without IFD (descripter.bin)Paul Menzel
On newer Intel systems, like Intel Lynx Point, the flash ROM is shared between the host processor (BIOS), its Management Engine (ME) and an integrated Ethernet controller (GbE). The layout of the flash ROM (and other information) is kept in the so called Intel Firmware Descriptor (IFD). If we only want to build coreboot to update the BIOS section, all we need is the flash layout. So add the option to specify the flash layout in the mainboard’s Kconfig, and thus, to build without the real IFD. However, with such a build, one has to make sure that the IFD section on the flash ROM will not be written over (nor any other section that has not been included by coreboot). A patch to write selected sections of a flash ROM with IFD has been sent to the flashrom mailing list [2]. The same was done in commit a15cd66b [1] (sandybridge: Make build possible without descriptor.bin) for Intel Sandy Bridge (BD82x6x).

2013-12-21lynxpoint: Route all USB ports to XHCI in finalize stepDuncan Laurie
This commit adds a new Kconfig option for the LynxPoint southbridge that will have coreboot route all of the USB ports to the XHCI controller in the finalize step (i.e. after the bootloader) and disable the EHCI controller(s). Additionally when doing this the XHCI USB3 ports need to be put into an expected state on resume in order to make the kernel state machine happy. Part of this could also be done in depthcharge but there are also some resume-time steps required so it makes sense to keep it all together in coreboot. This can theoretically save ~100mW at runtime. Verify that the EHCI controller is not found in Linux and that booting from USB still works.

2013-12-21lynxpoint me: add support for mbp clear wait in finalize stepDuncan Laurie
The management engine is slow, requiring at least 500ms between when the Dram Init Done message is sent (right after memory training) to when the MBP will report that it is successfully cleared and that the ME can finally be sent the EOP message. Currently this is adding 100-150ms to the boot time. If we defer waiting for the MBP Clear indicator until the finalize step we can gain back that lost time. boot on falco with SMI debugging enabled to ensure that the ME is locked down in the finalize step: Finalizing Coreboot SMI# #0 SMI_STS: PM1 APM ME: MBP cleared ME: mkhi_end_of_post ME: END OF POST message successful (0) Change-Id: Icab4c8c8e00eea67bed5e8154d91a1eb48a492d1 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: https://gerrit.chromium.org/gerrit/62633 Reviewed-by: Aaron Durbin <adurbin@chromium.org> Reviewed-on: http://review.coreboot.org/4375 Tested-by: build bot (Jenkins) Reviewed-by: Patrick Georgi <patrick@georgi-clan.de>

2013-03-19lynxpoint: Add cbfs_load_payload() implementationAaron Durbin
SPI accesses can be slow depending on the setup and the access pattern. The current SPI hardware setup to cache and prefetch. The alternative cbfs_load_payload() function takes advantage of the caching in the CPU because the ROM is cached as write protected as well as the SPI's hardware's caching/prefetching implementation. The CPU will fetch consecutive aligned cachelines which will hit the ROM as cacheline-aligned addresses. Once the payload is mirrored into RAM the segment loading can take place by reading RAM instead of ROM. With the alternative cbfs_load_payload() the boot time on a baskingridge board saves ~100ms. This savings is observed using cbmem.py after performing warm reboots and looking at TS_SELFBOOT_JUMP (99) entries. This is booting with a depthcharge payload whose payload file fits within the SMM_DEFAULT_SIZE (0x10000 bytes). Datapoints with TS_LOAD_PAYLOAD (90) & TS_SELFBOOT_JUMP (99) cbmem entries: Baseline Alt -------- -------- 90:3,859,310 (473) 90:3,863,647 (454) 99:3,989,578 (130,268) 99:3,888,709 (25,062) 90:3,899,450 (477) 90:3,860,926 (463) 99:4,029,459 (130,008) 99:3,890,583 (29,657) 90:3,834,600 (466) 90:3,890,564 (465) 99:3,964,535 (129,934) 99:3,920,213 (29,649) Booted baskingridge many times and observed 100ms reduction in TS_SELFBOOT_JUMP times (time to load payload).

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.
