2013-12-05google/link: use the new edid functions when in FUI modeRonald G. Minnich
The new edid functions support converting the edid to an lb_framebuffer. Use them. Also, since panels seem to set bits per color instead of bits per pixel, just force the right value in the edid struct. Add helpful comment because people don't always believe we need to set the pallette. While we're at it, fix a problem that caused it to not compile.

The BIOS spec for LynxPoint calls out additional programming steps for the PCIe Root Ports. Implement those steps from the BIOS spec. These steps are completed before deeper PCIe probing.

2013-12-05lynxpoint: disable pcie devices based on configAaron Durbin
PCIe Root Ports should be disabled based on pin ownership and the strapping configuration. Implement this logic for LynxPoint. The chip_ops->enable_dev() path is no longer used. Instead the PCIe driver handles the enabling and disabling of devices. This allows for having an empty or incomplete device tree since those "allocated" devices do not travel through the chip_ops->enable_dev() path. The coalescing was tested to be working properly, however not all configurations were tested.

2013-12-05Fix Makefile to include all copies of the SPD sourcesDuncan Laurie
On some systems there may be 2GB SKU that is the same as the 4GB SKU but just one channel of memory. In that case we need to ensure that both copies of the same SPD source end up populated by ensuring that repeated entries are included by using $+ instead of $^. Alternatively we could do the check inside romstage, but it is already set to behave this way if the SPD gets populated correctly.

2013-12-05AMD IMC AGESA: Access the data in stack by correct lengthZheng Bao
The bug is hard to find. We were adding the feature of fan control. We met some strange things which could not be explained. Like, sometimes adding printk let the error disappear. Then we traced the code by hardware debug tool (HDT). It turned out the data in stack was overwritten. The values of AccessWidthxx are { AccessWidth8 = 1, AccessWidth16, AccessWidth32,} For the case of AccessWidth8, we only need to access the index/data once. But ReadECmsg and WriteECmsg did the loop twice, 1 more time than they are supposed to do. The data in stack next to "Value" would be overwritten. For all the cases, the code should be OpFlag = OpFlag & 0x7f; switch (OpFlag) { case 1: /* AccessWidth8 */ OpFlag = 0;break; case 2: /* AccessWidth16 */ OpFlag = 1;break; case 3: /* AccessWidth32 */ OpFlag = 3;break; case 4: /* AccessWidth64 */ OpFlag = 7;break; default: error; } Actually, the caller only takes AccessWidth8 as the parameter. We can ignore other cases for now. That is an AGESA bug. AMD's AGESA team own this code. They have given the response that they are going to update this in next release. I presume let them decide the proper way to fix that. Before that, I change the code as little as possible to make it run without crash.

2013-12-05cpu: Remove BOARD_MICROCODE_CBFS_GENERATE Kconfig optionAlexandru Gagniuc
Commit * bdafcfa Add the Intel FSP 206ax CPU core support Introduced this option. This option was meant to have a board generate a CBFS file containing microcode. However, microcode generation used to be enabled by default when CPU_MICROCODE_IN_CBFS was selected. The introduction of BOARD_MICROCODE_CBFS_GENERATE killed that automatic default, which is not what we want. This option is misguided in the sense that it tends to introduce a non-default which had been intentionally a default. We now have to select two Kconfig options in order to generate microcode in CBFS, meaning one option is redundant.

2013-12-02elog: Get rid of the descriptor type and some unnecessary wrappersGabe Black
There was always exactly one elog descriptor declared and initialized, but its contents were being accessed through a pointer that was passed back and forth between functions instead of being accessed directly. This made the code more verbose than it needed to be and harder to follow. To address this the descriptor type was eliminated, its contents were turned into individual global variables, and various functions were adjusted to no longer take the descriptor as an argument. Similarly, the code was more verbose and complicated than it needed to be because of several wrapper functions which wrapped a single line of code which called an underlying function with particular arguments and were only used once. This makes it harder to tell what the code is doing because the call to the real function you may already be familiar with is obscured behind a new function you've never seen before. It also adds one more text to the file as a whole while providing at best a marginal benefit. Those functions were removed and their callers now call their contents directly.

2013-11-26Clean up POST codes for Boot State machineDuncan Laurie
Now that there is a clearly defined boot state machine we can add some useful post codes to indicate the current point in the state machine by having it log a post code before the execution of each state. This removes the currently defined POST codes that were used by hardwaremain in favor of a new contiguous range that are defined for each boot state. The reason for this is that the existing codes are mostly used to indicate when something is done, which is confusing for actual debug because POST code debugging relies on knowing what is about to happen (to know what may be at fault) rather than what has just finished. One additonal change is added during device init step as this step often does the bulk of the work, and frequently logs POST codes itself. Therefore in order to keep better track of what device is being initialized POST_BS_DEV_INIT is logged before each device is initialized. interrupted boot with reset button and gathered the eventlog.

2013-11-26Log device path into CMOS during probe stagesDuncan Laurie
One of the most common hangs during coreboot execution is during ramstage device init steps. Currently there are a set of (somewhat misleading) post codes during this phase which give some indication as to where execution stopped, but it provides no information on what device was actually being initialized at that point. This uses the new CMOS "extra" log banks to store the encoded device path of the device that is about to be touched by coreboot. This way if the system hangs when talking to the device there will be some indication where to investigate next. interrupted boot with reset button and gathered the eventlog after several test runs: 26 | 2013-06-10 10:32:48 | System boot | 120 27 | 2013-06-10 10:32:48 | Last post code in previous boot | 0x75 | Device Initialize 28 | 2013-06-10 10:32:48 | Extra info from previous boot | PCI | 00:16.0 29 | 2013-06-10 10:32:48 | Reset Button 30 | 2013-06-10 10:32:48 | System Reset Change-Id: I6045bd4c384358b8a4e464eb03ccad639283939c Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: https://gerrit.chromium.org/gerrit/58105 Reviewed-on: http://review.coreboot.org/4230 Tested-by: build bot (Jenkins) Reviewed-by: Alexandru Gagniuc <mr.nuke.me@gmail.com>

This is inappropriate because it forms a 1:1 mapping of USB device to disk leading to the inability to remove the disk and/or handle "hot plug" card insertion and removals. To alleviate this issue introduce the notion of ready to the usbmsc structure. It tracks detached, not ready, and ready states. The polling routine is then used to track not ready to ready transitions thereby creating and removing disks appropriately. This handles the case of inserting and removing a card that shows up as a new disk. Booted recovery mode. Able to observe inerstion and removal of sdcard.

If no media determination is found to be true the USB device is no longer considered a candidate to be a disk. This code does lead to the fact that the media card reader needs to be populated at enumeration time. I suspect this is not an issue as it appears the storage stack in libpayload can't handle removable media coming online later. Booted recovery and dev modes. Noted that removable mass storage devices with no media were ignored without any boot delay.

2013-11-25lynxpoint: Enable USB clock gating, late setup, and sleep prepDuncan Laurie
Both EHCI and XHCI controllers have additional setup steps that are not part of the PEI reference code so they need to be done later. Both controllers also have specific clock gating setup requirements that are now implemented. Additionally they both have specific requirements when entering sleep states. XHCI needs something in S3/S4/S5 and EHCI only has steps for S4/S5 entry.

2013-11-25haswell: check for clean resetAaron Durbin
When an INIT# is delivered to the CPU the CPU starts executing from the reset vector. However, the internal state is maintained. Therefore, check for such a condition and reset the system. Issues 'apreset warm' on the EC console. INIT# is sent and CPU notices it's not a clean reset and forces one. No hangs.
