2013-03-18rmodule: add 16 bytes of paddingAaron Durbin
There is a plan to utlize rmodules for loading ramstage as a relocatable module. However, the rmodule header may change. In order to provide some wiggle room for changing the contents of the rmodule header add some padding. This won't stop the need for coordinating properly between the romstage loader that may be in readonly flash and rmodule header fields. But it will provide for a way to make certain assumptions about alignment of the rmodule's program when the rmodule is compressed in the flash.

2013-03-18lib: add rmodule supportAaron Durbin
A rmodule is short for relocation module. Relocaiton modules are standalone programs. These programs are linked at address 0 as a shared object with a special linker script that maintains the relocation entries for the object. These modules can then be embedded as a raw binary (objcopy -O binary) to be loaded at any location desired. Initially, the only arch support is for x86. All comments below apply to x86 specific properties. The intial user of this support would be for SMM handlers since those handlers sometimes need to be located at a dynamic address (e.g. TSEG region). The relocation entries are currently Elf32_Rel. They are 8 bytes large, and the entries are not necessarily in sorted order. An future optimization would be to have a tool convert the unsorted relocations into just sorted offsets. This would reduce the size of the blob produced after being processed. Essentialy, 8 bytes per relocation meta entry would reduce to 4 bytes.

2013-03-18haswell: fix ACPI MCFG tableAaron Durbin
The acpi_fill_mcfg() was still using ivy/sandy PCI device ids which Hawell obviously doesn't have. This resulted in an empty MCFG table. Instead of relying on PCI device ids use dev/fn 0/0 since that is where the host bridge always resides. Additionally remove the defines for the IB and SB pci device ids. Replace them with mobile and ult Haswel device ids and use those in the pci driver tables for the northbridge code. Booted to Linux and noted that MCFG was properly parsed.

2013-03-18haswell: enable caching before SMM initializationAaron Durbin
The SMM handler resides in the TSEG region which is far above CONFIG_RAM_TOP (which is the highest cacheable address) before MTRRs are setup. This means that calling initialize_cpus() before performing MTRR setup on the BSP means the SMM handler is copied using uncacheable accesses. Improve the SMM handler setup path by enabling performing MTRR setup on for the BSP before the call to initialize_cpus(). In order to do this the haswell_init() function was split into 2 paths: BSP & AP paths. There is a cpu_common_init() that both call to perform similar functionality. The BSP path in haswell_init() then starts the APs using intel_cores_init(). The AP path in haswell_init() loads microcode and sets up MTRRs. This split will be leveraged for future support of bringing up APs in parallel as well as adhering to the Haswell MP initialization requirements.

2013-03-17haswell platforms: restructure romstage mainAaron Durbin
There was a mix of setup code sprinkled across the various components: southbridge code in the northbridge, etc. This commit reorganizes the code so that northbridge code doesn't initialize southbridge components. Additionally, the calling dram initialization no longer calls out to ME code. The main() function in the mainboard calls the necessary ME functions before and after dram initialization. The biggest change is the addition of an early_pch_init() function which initializes the BARs, GPIOs, and RCBA configuration. It is also responsible for reporting back to the caller if the board is being woken up from S3. The one sequence difference is that the RCBA config is performed before claling the reference code. Lastly the rcba configuration was changed to be table driven so that different board/configurations can use the same code. It should be possible to have board/configuration specific gpio and rcba configuration while reusing the romstage code.

The Link native graphics commit 49428d84 [1] Add support for Google's Chromebook Pixel was missing some of the higher level bits, and hence could not be used. This is not new code -- it has been working since last August -- so the effort now is to get it into the tree and structure it in a way compatible with upstream coreboot. 1. Add options to src/device/Kconfig to enable native graphics. 2. Export the MTRR function for setting variable MTRRs. 3. Clean up some of the comments and white space. While I realize that the product name is Pixel, the mainboard in the coreboot tree is called Link, and that name is what we will use in our commits.

2013-03-15AMD Fam14 DSDT: Add secondary bus range to PCI0Mike Loptien
Adding the 'WordBusNumber' macro to the PCI0 CRES ResourceTemplate in the Persimmon DSDT. This sets up the bus number for the PCI0 device and the secondary bus number in the CRS method. This change came in response to a 'dmesg' error which states: '[FIRMWARE BUG]: ACPI: no secondary bus range in _CRS' By adding the 'WordBusNumber' macro, ACPI can set up a valid range for the PCIe downstream busses, thereby relieving the Linux kernel from "guessing" the valid range based off _BBN or assuming [0-0xFF]. The Linux kernel code that checks this bus range is in `drivers/acpi/pci_root.c`. PCI busses can have up to 256 secondary busses connected to them via a PCI-PCI bridge. However, these busses do not have to be sequentially numbered, so leaving out a section of the range (eg. allowing [0-0x7F]) will unnecessarily restrict the downstream busses.

2013-03-15Persimmon DSDT: Remove INI method from AZHD deviceMike Loptien
I am removing the _INI method from the AZHD device because it does not seem to do anything and causes errors in the FWTS[1] (Firmware Test Suite) test 'method'. The INI method performs device specific initialization and is run when OSPM loads a description table. It must only access OperationRegions that have been indicated as available by the _REG (Region) method. We do not have a _REG method and during my testing, I added a REG method but it did not seem to make a difference in the PCI register space. The bit fields defined as NSDI (Disable No Snoop), NSDO (Disable No Snoop Override), and NSEN (Enable No Snoop Request) do not ever get written from their default values. And writing to these bit fields does not seem to be necessary because I did not notice any change in audio functionality. In an effort to clean up as many FWTS errors as possible, I propose removing this method altogether. I have seen no change in operation (audio works with and without this method) and there does not seem to be any change in lspci or dmesg.

2013-03-15haswell: resource allocationAaron Durbin
The previous code w.r.t. resource allocation was getting lucky based on the way fixed mmio resources on the system were being chosen. Namely, PCIEXBAR was the lowest mmio space and the other fixed non-standar BARs were above it. The resource allocator would then start allocating standard BARs below that. On top of that other resources were being added when dev_ops->set_resources() was being called on the PCI domain. At that point the PCI range limit were already picked for where to start allocating from. To ensure we no longer get lucky during resource allocation add the fixed resources in the host bridge and add the memory controller cacheable memory areas. With those resources added the range limit for standard PCI BARs is chosen properly.

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 CS5536 companion device has three different power domains. * working domain * standby domain * RTC domain When the system is "off" only the standby domain is powered. MFGPT[7:6] are member of the standby power domain. MFGPT7 is used to control the backlight of the device and so the timer gets used and configured during system boot.

2013-03-14x86: SMM Module SupportAaron Durbin
Add support for SMM modules by leveraging the RMODULE lib. This allows for easier dynamic SMM handler placement. The SMM module support consists of a common stub which puts the executing CPU into protected mode and calls into a pre-defined handler. This stub can then be used for SMM relocation as well as the real SMM handler. For the relocation one can call back into coreboot ramstage code to perform relocation in C code. The handler is essentially a copy of smihandler.c, but it drops the TSEG differences. It also doesn't rely on the SMM revision as the cpu code should know what processor it is supported. Ideally the CONFIG_SMM_TSEG option could be removed once the existing users of that option transitioned away from tseg_relocate() and smi_get_tseg_base(). The generic SMI callbacks are now not marked as weak in the declaration so that there aren't unlinked references. The handler has default implementations of the generic SMI callbacks which are marked as weak. If an external compilation module has a strong symbol the linker will use that instead of the link one. Additionally, the parameters to the generic callbacks are dropped as they don't seem to be used directly. The SMM runtime can provide the necessary support if needed.

Adding the 'WordBusNumber' macro to the PCI0 CRES ResourceTemplate in the Persimmon DSDT. This sets up the bus number for the PCI0 device and the secondary bus number in the CRS method. This change came in response to a 'dmesg' error which states: '[FIRMWARE BUG]: ACPI: no secondary bus range in _CRS' By adding the 'WordBusNumber' macro, ACPI can set up a valid range for the PCIe downstream busses, thereby relieving the Linux kernel from "guessing" the valid range based off _BBN or assuming [0-0xFF]. The Linux kernel code that checks this bus range is in `drivers/acpi/pci_root.c`. PCI busses can have up to 256 secondary busses connected to them via a PCI-PCI bridge. However, these busses do not have to be sequentially numbered, so leaving out a section of the range (eg. allowing [0-0x7F]) will unnecessarily restrict the downstream busses. This change will apply to other AMD mainboards and will be in a different commit.
