Stefan Reinauer (stefan.reinauer(a)coreboot.org) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/2618 -gerrit commit 6ab7d97a526a7756648030a11833591ecb9741fb Author: Aaron Durbin <adurbin(a)chromium.org> Date: Wed Oct 31 23:05:25 2012 -0500 haswell: remove explicit pcie config accesses Now that MMCONF_SUPPORT_DEFAULT is enabled by default remove the pcie explicit accesses. The default config accesses use MMIO.

New patch to review for coreboot: e95821a haswell: Add initial support for Haswell platforms
by Stefan Reinauer 09 Mar '13

09 Mar '13

Stefan Reinauer (stefan.reinauer(a)coreboot.org) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/2616 -gerrit commit e95821aa0ce8cea2a055d290db5e42c432103056 Author: Aaron Durbin <adurbin(a)chromium.org> Date: Tue Oct 30 09:03:43 2012 -0500 haswell: Add initial support for Haswell platforms 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.

Patch set updated for coreboot: d234471 AMD Inagua: add GEC firmware, document Broadcom BCM57xx Selfboot Patch format
by Jens Rottmann 09 Mar '13

09 Mar '13

Jens Rottmann (JRottmann(a)LiPPERTembedded.de) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/2581 -gerrit commit d234471d1e702ed816f33c7031aa6ddeabb6f728 Author: Jens Rottmann <JRottmann(a)LiPPERTembedded.de> Date: Fri Mar 1 19:41:41 2013 +0100 AMD Inagua: add GEC firmware, document Broadcom BCM57xx Selfboot Patch format The Broadcom BCM5785 GbE MAC integrated in the AMD Hudson-E1 requires a secret sauce firmware blob to work. As Broadcom wasn't willing to send us any documentation (or a firmware adapted to our Micrel PHY) I had to figure out everything by myself in many weeks of hard detective work. In the end we had to settle for a different solution, the modified firmware I devised for the Micrel KSZ9021 PHY on our early FrontRunner-AF prototypes is no longer needed for the production version. However the information contained here might be very useful for others who'd like to use a competing PHYs instead of Broadcom's 50610, so it should not get lost. And of course the unmodified, but now in large parts documented Selfboot Patch is needed to get Ethernet on AMD Inagua. The fun thing is: as Broadcom refused to do any business with us at all, or send us any documentation, we never had to sign an NDA with them. This leaves me free to publish everything I have found out. :-) Change-Id: Ifa628751d14143f277b27cfd34b1d2771ca1302f Signed-off-by: Jens Rottmann <JRottmann(a)LiPPERTembedded.de> --- src/mainboard/amd/inagua/Makefile.inc | 2 +- src/mainboard/amd/inagua/broadcom.c | 360 ++++++++++++++++++++++++++++++++++ src/mainboard/amd/inagua/mainboard.c | 4 + 3 files changed, 365 insertions(+), 1 deletion(-) diff --git a/src/mainboard/amd/inagua/Makefile.inc b/src/mainboard/amd/inagua/Makefile.inc index 17443bc..b84a03a 100644 --- a/src/mainboard/amd/inagua/Makefile.inc +++ b/src/mainboard/amd/inagua/Makefile.inc @@ -35,4 +35,4 @@ ramstage-y += BiosCallOuts.c ramstage-y += PlatformGnbPcie.c ramstage-y += reset.c - +ramstage-y += broadcom.c diff --git a/src/mainboard/amd/inagua/broadcom.c b/src/mainboard/amd/inagua/broadcom.c new file mode 100644 index 0000000..357fdbc --- /dev/null +++ b/src/mainboard/amd/inagua/broadcom.c @@ -0,0 +1,360 @@ +/* + * Initialize Broadcom 5785 GbE MAC embedded in AMD A55E (Hudson-E1) Southbridge + * by uploading a Selfboot Patch to the A55E's shadow ROM area.

The A55E doesn't have any balls for an ext. + * EEPROM, instead AMD added a small internal RAM. The BIOS is expected to copy + * the correct contents into this RAM (which only supports byte access!) upon + * each powerup. The A55E can trigger an SMI upon writes, enabling the BIOS to + * forward any changes to an actually 'NV' location, e.g. the BIOS's SPI flash, + * behind the scenes. AMD calls it "GEC shadow ROM", not describing what it's + * for nor mentioning the term "NVRAM". broadcom_init() below documents a + * procedure how to upload the patch. No SMI magic is installed, therefore + * 'NV'RAM writes won't be persistent. + * + * The "Selfboot Patch" can execute simple commands at various points during + * main firmware execution. This can be used to change config registers, + * initialize a specific PHY or work around firmware bugs. Broadcom provides + * suitable Patches only for their AC131 and 50610 PHYs (as binary blobs). I + * found them in DOS\sb_patch\5785\*\sb5785*.* in Driver_14_6_4_2.zip.

Patch set updated for coreboot: 7ae89c2 AMD Inagua: add GEC firmware, document Broadcom BCM57xx Selfboot Patch format
by Jens Rottmann 09 Mar '13

09 Mar '13

Jens Rottmann (JRottmann(a)LiPPERTembedded.de) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/2581 -gerrit commit 7ae89c2ee20698137ef484cf867e8d3854ce1bbe Author: Jens Rottmann <JRottmann(a)LiPPERTembedded.de> Date: Fri Mar 1 19:41:41 2013 +0100 AMD Inagua: add GEC firmware, document Broadcom BCM57xx Selfboot Patch format The Broadcom BCM5785 GbE MAC integrated in the AMD Hudson-E1 requires a secret sauce firmware blob to work. As Broadcom wasn't willing to send us any documentation (or a firmware adapted to our Micrel PHY) I had to figure out everything by myself in many weeks of hard detective work. In the end we had to settle for a different solution, the modified firmware I devised for the Micrel KSZ9021 PHY on our early FrontRunner-AF prototypes is no longer needed for the production version. However the information contained here might be very useful for others who'd like to use a competing PHYs instead of Broadcom's 50610, so it should not get lost. And of course the unmodified, but now in large parts documented Selfboot Patch is needed to get Ethernet on AMD Inagua. The fun thing is: as Broadcom refused to do any business with us at all, or send us any documentation, we never had to sign an NDA with them. This leaves me free to publish everything I have found out. :-) Change-Id: Ifa628751d14143f277b27cfd34b1d2771ca1302f Signed-off-by: Jens Rottmann <JRottmann(a)LiPPERTembedded.de> --- src/mainboard/amd/inagua/Makefile.inc | 2 +- src/mainboard/amd/inagua/broadcom.c | 360 ++++++++++++++++++++++++++++++++++ src/mainboard/amd/inagua/mainboard.c | 4 + 3 files changed, 365 insertions(+), 1 deletion(-) diff --git a/src/mainboard/amd/inagua/Makefile.inc b/src/mainboard/amd/inagua/Makefile.inc index b1a3014..1f653b5 100644 --- a/src/mainboard/amd/inagua/Makefile.inc +++ b/src/mainboard/amd/inagua/Makefile.inc @@ -37,4 +37,4 @@ ramstage-y += BiosCallOuts.c ramstage-y += PlatformGnbPcie.c ramstage-y += reset.c - +ramstage-y += broadcom.c diff --git a/src/mainboard/amd/inagua/broadcom.c b/src/mainboard/amd/inagua/broadcom.c new file mode 100644 index 0000000..357fdbc --- /dev/null +++ b/src/mainboard/amd/inagua/broadcom.c @@ -0,0 +1,360 @@ +/* + * Initialize Broadcom 5785 GbE MAC embedded in AMD A55E (Hudson-E1) Southbridge + * by uploading a Selfboot Patch to the A55E's shadow ROM area.

The firmware loads config data and supplements (e.g. to + * support specific PHYs), named "Selfboot Patches", via the "NVRAM Interface", + * usually from an external EEPROM. The A55E doesn't have any balls for an ext. + * EEPROM, instead AMD added a small internal RAM. The BIOS is expected to copy + * the correct contents into this RAM (which only supports byte access!) upon + * each powerup. The A55E can trigger an SMI upon writes, enabling the BIOS to + * forward any changes to an actually 'NV' location, e.g. the BIOS's SPI flash, + * behind the scenes. AMD calls it "GEC shadow ROM", not describing what it's + * for nor mentioning the term "NVRAM". broadcom_init() below documents a + * procedure how to upload the patch. No SMI magic is installed, therefore + * 'NV'RAM writes won't be persistent. + * + * The "Selfboot Patch" can execute simple commands at various points during + * main firmware execution. This can be used to change config registers, + * initialize a specific PHY or work around firmware bugs. Broadcom provides + * suitable Patches only for their AC131 and 50610 PHYs (as binary blobs).

Patch merged into coreboot/master: 4733c64 Persimmon DSDT: Add secondary bus range to PCI0
by gerrit＠coreboot.org 08 Mar '13

08 Mar '13

the following patch was just integrated into master: commit 4733c647bc64cef86f03efd64a145e4da6fef123 Author: Mike Loptien <mike.loptien(a)se-eng.com> Date: Tue Mar 5 14:21:28 2013 -0700 Persimmon DSDT: Add secondary bus range to PCI0 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.
