2013-03-30armv7: import new cache maintenance API from corebootDavid Hendricks
This imports the new cache maintenance API from coreboot at commit bba8090. This is a BSD-licensed implementation which exposes cache maintenance opertaions necessary for payloads for things such as DMA transfers.

2013-03-30inteltool: Add Cougar/Panther Point IDs to rootcmplx.cNico Huber
This adds the PCI IDs of Intel's Cougar Point and Panther Point platform controller hubs (PCH) to the dumping of the root complex configuration under the root complex base address (RCBA). Those PCHs are handled exactly as the older ICHs which can be seen in [1] and [2]. I've tested dumping with an H77 PCH. NM70 is missing in [1]. Therefore, I didn't add it here.

2013-03-30AMD Hudson boards: Use `hudson.h` for `pm_ioread` and delete `pmio.h`Paul Menzel
Unfortunately, an unneeded mainboard specific `pmio.h` was created when merging the AMD Parmer and Thatcher ports. Rudolf used the header from a more generic location southbridge/amd/agesa/hudson/hudson.h doing the the ASUS F2A85-M port, but did not delete the `pmio.h` now unused `pmio.h` header file. So adapt AMD Parmer and Thatcher to use the Hudson one as done for the ASUS F2A85-M and delete the now unused mainboard specific header file `pmio.h` to avoid duplication.

2013-03-29x86: mtrr: optimize hole carving above 4GiBAaron Durbin
There is an optimization that can take place when hole carving in ranges above 4GiB. If the range is the last range then there is no need to carve UC holes out from the larger WB range. This optimization also has the same assumption of choosing WB as the default MTRR type: the OS needs to properly handle accessing realloacted MMIO resources with PAT so that the MTRR type can be overidden. Below are results using a combination of options. The board this was tested on has 10 variable MTRRs at its disposal. It has 4GiB of RAM.

2013-03-29x86: mtrr: add hole punching supportAaron Durbin
Some ranges would use less variable MTRRs if an UC area can be carved off the top of larger WB range. Implement this approach by doing 3 passes over each region in the addres space: 1. UC default type. Cover non-UC and non-WB regions with respectie type. Punch UC hole at upper end of larger WB regions with WB type. 2. UC default type. Cover non-UC regions with respective type. 3. WB default type. Cover non-WB regions with respective type. The hole at upper end of a region uses the same min alignment of 64MiB. Below are results using a combination of options. The board this was tested on has 10 variable MTRRs at its disposal. It has 4GiB of RAM.

2013-03-29memrange: add 2 new range_entry routinesAaron Durbin
Two convenience functions are added to operate on a range_entry: - range_entry_update_tag() - update the entry's tag - memranges_next_entry() - get the next entry after the one provide These functions will be used by a follow on patch to the MTRR code to allow hole punching in WB region when the default MTRR type is UC.

On x86, coreboot may allocate a variable range MTRR for enabling caching of the system ROM. Add the ability to parse this structure and add the result to the sysinfo structure. An example usage implementation would be to obtain the variable MTRR index that covers the ROM from the sysinfo structure. Then one would disable caching and change the MTRR type from uncacheable to write-protect and enable caching. The opposite sequence is required to tearn down the caching.

2013-03-29x86: mtrr: add CONFIG_CACHE_ROM supportAaron Durbin
The CONFIG_CACHE_ROM support in the MTRR code allocates an MTRR specifically for setting up write-protect cachine of the ROM. It is assumed that CONFIG_ROM_SIZE is the size of the ROM and the whole area should be cached just under 4GiB. If enabled, the MTRR code will allocate but not enable rom caching. It is up to the callers of the MTRR code to explicitly enable (and disable afterwards) through the use of 2 new functions: - x86_mtrr_enable_rom_caching() - x86_mtrr_disable_rom_caching() Additionally, the CACHE_ROM option is exposed to the config menu so that it is not just selected by the chipset or board. The reasoning is that through a multitude of options CACHE_ROM may not be appropriate for enabling.

2013-03-29resources: remove IORESOURCE_[UMA_FB|IGNORE_MTRR]Aaron Durbin
The IORESOURCE_UMA_FB and IORESOURCE_IGNORE_MTRR attributes on a resource provided hints to the MTRR algorithm. The IORESOURCE_UMA_FB directed the MTRR algorithm to setup a uncacheable space for the resource. The IORESOURCE_IGNORE_MTRR directed the MTRR algorithm to ignore this resource as it was used reserving RAM space. Now that the optimizing MTRR algorithm is in place there isn't a need for these flags. All IORESOURCE_IGNORE_MTRR users are handled by the MTRR code merging resources of the same cacheable type. The users of the IORESOURCE_UMA_FB will find that the default MTRR type calculation means there isn't a need for this flag any more.

2013-03-29x86: add new mtrr implementationAaron Durbin
The old MTRR code had issues using too many variable MTRRs depending on the physical address space layout dictated by the device resources. This new implementation calculates the default MTRR type by comparing the number of variable MTRRs used for each type. This avoids the need for IORESOURE_UMA_FB because in many of those situations setting the default type to WB frees up the variable MTTRs to set that space to UC. Additionally, it removes the need for IORESOURCE_IGNORE_MTRR becuase the new mtrr uses the memrange library which does merging of resources. Lastly, the sandybridge gma has its speedup optimization removed for the graphics memory by writing a pre-determined MTRR index. That will be fixed in an upcoming patch once write-combining support is added to the resources. Slight differences from previous MTRR code: - The number of reserved OS MTRRs is not a hard limit. It's now advisory as PAT can be used by the OS to setup the regions to the caching policy desired. - The memory types are calculated once by the first CPU to run the code. After that all other CPUs use that value. - CONFIG_CACHE_ROM support was dropped. It will be added back in its own change. A pathological case that was previously fixed by changing vendor code to adjust the IO hole location looked like the following: MTRR: Physical address space: 0x0000000000000000 - 0x00000000000a0000 size 0x000a0000 type 6 0x00000000000a0000 - 0x00000000000c0000 size 0x00020000 type 0 0x00000000000c0000 - 0x00000000ad800000 size 0xad740000 type 6 0x00000000ad800000 - 0x00000000d0000000 size 0x22800000 type 0 0x00000000d0000000 - 0x00000000e0000000 size 0x10000000 type 1 0x00000000e0000000 - 0x0000000100000000 size 0x20000000 type 0 0x0000000100000000 - 0x000000014f600000 size 0x4f600000 type 6 As noted by the output below it's impossible to accomodate those ranges even with 10 variable MTRRS. However, because the code can select WB as the default MTRR type it can be done in 6 MTRRs: MTRR: default type WB/UC MTRR counts: 6/14. MTRR: WB selected as default type. MTRR: 0 base 0x00000000ad800000 mask 0x0000007fff800000 type 0 MTRR: 1 base 0x00000000ae000000 mask 0x0000007ffe000000 type 0 MTRR: 2 base 0x00000000b0000000 mask 0x0000007ff0000000 type 0 MTRR: 3 base 0x00000000c0000000 mask 0x0000007ff0000000 type 0 MTRR: 4 base 0x00000000d0000000 mask 0x0000007ff0000000 type 1 MTRR: 5 base 0x00000000e0000000 mask 0x0000007fe0000000 type 0 Change-Id: Idfcc78d9afef9d44c769a676716aae3ff2bd79de Signed-off-by: Aaron Durbin <adurbin@chromium.org> Reviewed-on: http://review.coreboot.org/2889 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>
