2017-02-20lynxpoint/broadwell: fix PCH power optimizerMatt DeVillier
Setting both bits 27 and 7 of PCH register PMSYNC_CFG (PMSYNC Configuration; offset 0x33c8) causes pre-OS display init to fail on HSW-U/Lynxpoint and BDW-U ChromeOS devices when the VBIOS/GOP driver is run after the register is set. A re-examination of Intel's reference code reveals that bit 7 should be set for the LP PCH, and bit 27 for non-LP, but not both simultaneously. The previous workaround was to disable the entire power optimizer section via a Kconfig option, which isn't ideal. Test: unset bit 27 of PMSYNC_CFG and boot google/lulu, observe functional pre-OS video output Change-Id: I446e169d23dd446710a1648f0a9b9599568b80aa Signed-off-by: Matt DeVillier <matt.devillier@gmail.com> Reviewed-on: https://review.coreboot.org/18385 Tested-by: build bot (Jenkins) Reviewed-by: Martin Roth <martinroth@google.com> Reviewed-by: Duncan Laurie <dlaurie@chromium.org>

2015-05-21Remove address from GPLv2 headersPatrick Georgi
As per discussion with lawyers[tm], it's not a good idea to shorten the license header too much - not for legal reasons but because there are tools that look for them, and giving them a standard pattern simplifies things. However, we got confirmation that we don't have to update every file ever added to coreboot whenever the FSF gets a new lease, but can drop the address instead. util/kconfig is excluded because that's imported code that we may want to synchronize every now and then. $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, *MA[, ]*02110-1301[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin Street, Suite 500, Boston, MA 02110-1335, USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 59 Temple Place[-, ]*Suite 330, Boston, MA *02111-1307[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.:Foundation, Inc.:" {} + $ find * -type f -a \! -name \*.patch \ -a \! -name \*_shipped \ -a \! -name LICENSE_GPL \ -a \! -name LGPL.txt \ -a \! -name COPYING \ -a \! -name DISCLAIMER \ -exec sed -i "/Foundation, Inc./ N;s:Foundation, Inc.* USA\.* *:Foundation, Inc. :;s:Foundation, Inc. $:Foundation, Inc.:" {} + Change-Id: Icc968a5a5f3a5df8d32b940f9cdb35350654bef9 Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Reviewed-on: http://review.coreboot.org/9233 Tested-by: build bot (Jenkins) Reviewed-by: Vladimir Serbinenko <phcoder@gmail.com>

2014-10-22cmos: Rename the CMOS related functions.Gabe Black
Most of the code related to the mc146818 is not related to the RTC and is really for managing the CMOS storage. Since we intend to add a generic API for RTC drivers it's inconvenient for those functions to have an rtc_ prefix. This CL renames those functions so they start with cmos_ instead. There are some places where rtc_init was called with a comment that says something about starting the RTC. That wasn't correct before (the RTC is always running), but it looks a little odd now that the function is called cmos_init. This CL also opportunistically cleans up some style problems in this file.

2013-04-01lynxpoint: Move ACPI NVS into separate CBMEM tableDuncan Laurie
The ACPI NVS region was setup in place and there was a CBMEM table that pointed to it. In order to be able to use NVS earlier the CBMEM region is allocated for NVS itself during the LPC device init and the ACPI tables point to it in CBMEM. The current cbmem region is renamed to ACPI_GNVS_PTR to indicate that it is really a pointer to the GNVS and does not actually contain the GNVS.

2013-03-21haswell/lynxpoint: Use new PCH/PM helper functionsDuncan Laurie
This makes use of the new functions from pmutil.c that take care of the differences between -H and -LP chipsets. It also adds support for the LynxPoint-LP GPE0 register block and the SMI/SCI routing differences. The FADT is updated to report the new 256 byte GPE0 block on wtm2/wtm2 boards which is too big for the 64bit X_GPE0 address block so that part is zeroed to prevent IASL and the kernel from complaining about a mismatch. This was tested on WTM2. Unfortunately I am still unable to get an SCI delivered from the EC but I suspect that is due to a magic command needed to put the EC in ACPI mode. Instead I verified that all of the power management and GPIO registers were set to expected values. I also tested transitions into S3 and S5 from both the kernel and by pressing the power button at the developer mode screen and they all function as expected.

2013-03-21lynxpoint: Fix GPIO and PM base reservationsDuncan Laurie
The kernel ACPI was not happy with the Add inside a ResourceTemplate (or perhaps within the IO declaration) Instead make a buffer of IO reservations and turn _CRS into a method that updates the buffer depending on the chipset type. This adds an \ISLP() method that checks the chipset LPC device ID to see if it is -LP or -H. It also increases the PM base reservation to 256 bytes and moves both GPIO and PM base to above 0x1000 on -LP chipsets.

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.

2013-03-14lynxpoint: lpc resource reservationsAaron Durbin
This commit updates the Lynx Point resource reservations before the coreboot allocator assigns resources. There is no need to mark anything as subtractive decode because there are no devices/buses linked to the LPC device. The I/O range reservations consists of claiming the first 4KiB of I/O space. The PMBASE, GPIOBASE, and LPC generic I/O decode ranges are checked against the default claimed range. If those ranges overlap or fall outside of the default range then those resources are added. The MMIO range reservations consist of claiming everything from the I/O APIC to 4GiB. The RCBA and the LPC Generic Memory range register are then conditionally added if they fall outside of the default MMIO range.

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.
