2015-10-31tree: drop last paragraph of GPL copyright headerPatrick Georgi
It encourages users from writing to the FSF without giving an address. Linux also prefers to drop that and their checkpatch.pl (that we imported) looks out for that. This is the result of util/scripts/no-fsf-addresses.sh with no further editing.

2015-10-23Intel: Move MCRS ResourceTemplate outside of _CRS methodMartin Roth
On Broadwell, this reduces the number of 'remarks' in the IASL build from 222 to 3. Fixes these remarks: Object is not referenced (Name is within method [_CRS]) The ACPI compiler is trying to be helpful in letting us know that we're not using various fields in the MCRS ResourceTemplate when we define it inside of the _CRS method. Since we're not intending to use those objects in the method, it shouldn't be an issue, but the warning is annoying and can mask real issues. Moving the creation of the MCRS object to outside of the CRS method and referencing it from there solves this problem.

2015-09-07intel: Do not hardcode the position of mrc.cacheAlexandru Gagniuc
The reason for hardcoding the position of the MRC cache was to satisfy the alignment to the erase size of the flash chip. Hardcoding is no longer needed, as we can specify alignment directly. In the long term, the MRC cache will have to move to FMAP, but for now, we reduce fragmentation in CBFS. Note that soc/intel/common hardcoding of mrc.cache is not removed, as the mrc cache implementation there does not use CBFS to find the cache region, and needs a hardcoded address.

2015-06-02cbfs: new API and better program loadingAaron Durbin
A new CBFS API is introduced to allow making CBFS access easier for providing multiple CBFS sources. That is achieved by decoupling the cbfs source from a CBFS file. A CBFS source is described by a descriptor. It contains the necessary properties for walking a CBFS to locate a file. The CBFS file is then decoupled from the CBFS descriptor in that it's no longer needed to access the contents of the file. All of this is accomplished using the regions infrastructure by repsenting CBFS sources and files as region_devices. Because region_devices can be chained together forming subregions this allows one to decouple a CBFS source from a file. This also allows one to provide CBFS files that came from other sources for payload and/or stage loading. The program loading takes advantage of those very properties by allowing multiple sources for locating a program. Because of this we can reduce the overhead of loading programs because it's all done in the common code paths. Only locating the program is per source.

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>

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.

As a first step towards removing hardcodes from the FUI support, change the haswell call to i915_lightup to panel_lightup, and pass the intel_dp * as a parameter. Get rid of the scalar arguments and make them part of intel_dp. Get rid of file-scope variables and use the ones in the intel_dp struct. In falco, use functions that peppy uses. Drop slippy support for FUI, it's a dead board; if this is ok I'll remove the files next. And, incidentally, fix the broken RGBX constant and change it to BGRX.

2014-08-25intel/gma: Clarify code and use dedicated init for Google PeppyRonald G. Minnich
Peppy had some issues with FUI. We decided it was time to create peppy-specific gma.c and i915io.c files. Using yabel and the i915tool, we generated a replay attack, then interpolated against the slippy i915io.c to get something working. Also, in preparation for moving code out of the mainboard gma.c to generic driver code, we got rid of some hardcodes in the mainboard gma.c that have no business being there. The worst were the computation of gmch_[m,n] and it turns out that we had some long-standing bugs related to confusion about 'bpp'. I've killed the word bpp everywhere I could because there are at least 3 things that correspond to bpp. We now have framebuffer, pipe, and panel bpp. The names are long because I want to avoid all the mistakes we've all been making in the last year :-) Sadly, that means a lot of changes not just peppy-related, but they are simple and in a good cause. The test pattern generation is driven by a global variable in mainboard/peppy/gma.c. I've found in the past that it's very useful to have a function like this available, as one can activate it while using a jtag debugger: halt at the right place in ramstage, set the variable to 1, continue. It's not enough code to worry about always including. The last hard-codes for M and N registers are gone, and the function to set from generic intel_dp.c code works. To avoid screen trash on a dev mode boot, which we liked but nobody else did :-), we now take the time to put a pleasing background color that sort of doubles as a power LED. Rough timing is ramstage start is at 2.2, and dev setup is done at 3.3. These new platforms are depressingly slow to boot. Rom init alone is taking 1.9 seconds. 13 years ago it was 3 seconds from power on to bash prompt. These CPUs are at least 10x faster and take much longer to get going. Future work, once we get this through, is to move more functions to the intel driver, and combine the mainboard i915io.c into the mainboard gma.c. That separation only existed because i915io.c was generated by a tool, and it had lots of ugliness. Most ugliness is gone.

2013-12-21haswell: Add pei_data field for USB routingDuncan Laurie
The linux kernel will unconditionally route all USB ports to the XCHI controller at boot. The EHCI controller can then be disabled, and it should be left disabled by the reference code when this is done. However not all OS may do this unconditional route, so provide an option to the reference code binary to enable this behavior.

2013-12-12HDA: Enable Mini-HDA and fix up PCH-HDA initDuncan Laurie
The SystemAgent contains a mini-hd audio controller at PCI 0:3.0 which uses the same verb table init sequence as the southbridge. In order to avoid two copies of the verb table loading code I separated out the HDA verb table functions into a file that can be re-used and then added a minihd driver to the haswell northbridge. The minihd verb table is the same across devices so it can live within the minihd driver rather than needing to be specified in each separate mainboard. I also fixed up the driver for lynxpoint HDA by following the reference code. Without HDMI cable plugged in driver does not find any codec, and it does not seem to re-probe when HDMI is connected. We may be missing kernel patches for this. hda-intel 0000:00:03.0: no codecs found! With a basic kernel patch to add 0x0a0c device ID to HDA driver and with HDMI cable connected it is much happier: snd_hda_intel 0000:00:03.0: irq 60 for MSI/MSI-X input: HDA Intel MID HDMI/DP,pcm=3 as /devices/pci0000:00/0000:00:03.0/sound/card0/input9 snd_hda_intel 0000:00:1b.0: irq 61 for MSI/MSI-X input: HDA Intel PCH Mic as /devices/pci0000:00/0000:00:1b.0/sound/card1/input10 input: HDA Intel PCH Headphone as /devices/pci0000:00/0000:00:1b.0/sound/card1/input11 Change-Id: Ifa587984be4fc2801704a0368b9cdf8379c2450e Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: https://gerrit.chromium.org/gerrit/59336 Reviewed-by: Aaron Durbin <adurbin@chromium.org> Reviewed-on: http://review.coreboot.org/4318 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.

2013-07-09fox_wtm2: First step support for coreboot-based graphics startupRonald G. Minnich
This code is the initial version of FUI for haswell and wtm2. The code is simplified from before in many ways. I've gotten rid of the opcode table, because it obscured meaning and I don't think it is needed any more. Register sets, mainly used for reset, are just lines of code -- not many of them. There are a bunch of not-yet-documented registers here; the VBIOS seemed to think they were necessary and testing shows they seem to be right. As a bit of added paranoia, we always include the VBIOS code as our emergency recovery path. You have to run it now anyways, so this is no regression from our current situation; and, if all goes well, in a week (or so), you'll never have to run it again, but like the Force and nose hair, it will be with you always. The code can return in three ways. The first, best way is success: panel is up and the VBIOS need not run. The second mode is that we tried to light up the panel but could not, for some reason, but will return with the panel partly up. In this case, it's ok not to power cycle the panel. The third, worst case, which will NEVER happen, ha ha, is that we have to turn the panel off and wait the required 600ms for it to cycle. Life sucks sometimes. This failure mode is in the 'hang on we're going to fix it' category now that we have ramstage in RW. The Big Goal here is to create something other coreboot ports can use as well. The guys doing the x60 report that the link FUI works, without too many mods, on that chipset, so it seems Intel is keeping things from changing too much over time. Also, again, please note: this and the next 3 versions will ALWAYS fail. The goal is to verify the correctness of the recovery path.

2013-03-22x86: Unify arch/io.h and arch/romcc_io.hStefan Reinauer
Here's the great news: From now on you don't have to worry about hitting the right io.h include anymore. Just forget about romcc_io.h and use io.h instead. This cleanup has a number of advantages, like you don't have to guard device/ includes for SMM and pre RAM anymore. This allows to get rid of a number of ifdefs and will generally make the code more readable and understandable. Potentially in the future some of the code in the io.h __PRE_RAM__ path should move to device.h or other device/ includes instead, but that's another incremental change.

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.

2013-03-21haswell: add multipurpose SMM memory regionAaron Durbin
The SMM region is available for multipurpose use before the SMM handler is relocated. Provide a configurable sized region in the TSEG for use before the SMM handler is relocated. This feature is implemented by making the reserved size a Kconfig option. Also make the IED region a Kconfig option as well. Lastly add some sanity checking on the Kconfig options.

2013-03-21haswell: use s3_resume field in romstage_handoffAaron Durbin
Now that there is a way to disseminate the presence of s3 wake more formally use that instead of hard coded pointers in memory and stashing magic values in device registers. The northbridge code picks up the field's presence in the romstage_handoff structure and sets up the acpi_slp_type variable accordingly.

2013-03-18haswell: move call site of save_mrc_data()Aaron Durbin
The save_mrc_data() was previously called conditionally in the raminit code. The save_mrc_data() function was called in the non-S3 wake paths. However, the common romstage_common() code was checking cbmem initialization things on s3 wake. Between the two callers cbmem_initialize() was being called twice in the non-s3 wake paths. Moreover, saving of the mrc data was not allowed when CONFIG_EARLY_CBMEM_INIT wasn't enabled. Therefore, move the save_mrc_data() to romstage_common. It already has the knowledge of the wake path. Also remove the CONFIG_EARLY_CBMEM_INIT requirement from save_mrc_data() as well as the call to cbmem_initialize().
