-From 34f8cdbc30f1fdf4700c73aad26e0fc159af70ab Mon Sep 17 00:00:00 2001
-From: Arthur Heymans <arthur@aheymans.xyz>
-Date: Fri, 2 Sep 2016 22:35:32 +0200
-Subject: [PATCH 1/2] i945/gma.c use latest linux code to calculate divisors.
-
-The code to compute n, m1, m2, p1 divisors is not correct in coreboot and
-on some targets hits a working mode at lower refresh rate, which is why
-display is working on some targets.
-This patch also fixes reference frequency.
-
-This patch reuses linux code to correctly compute divisors.
-
-The result is that some previously not working displays (Lenovo T60 with
-1024x786, 1400x1050, 2048x1536)
-
-TESTED on T60 with 1024x786.

-Subject: [PATCH 2/2] i945/gma.c: add native VGA init
-
-This reuses the Intel Pineview native graphic initialization
-to have output on the VGA connector of i945 devices.
-
-The behavior is the same as with the vendor VBIOS BLOB.
-It uses the external VGA display if it is connected.

-Subject: [PATCH] i945/gma.c: generate fake VBT
-
-This generates a fake VBT for the Intel i945 graphic device.
-i945 supports both the mobile chipset 945gm (calistoga)
-and the desktop chipset 945gc (lakeport),
-which is why a VBT with a different id string
-needs to be created for each target.
-
-The VBT id string is obtained from the vbios blob in the following way:
-"strings vbios.bin | grep VBT".

-Subject: [PATCH] lenovo/t60: add hda_verb.c
-
-This creates a config for the Lenovo T60 sound card based
-on values taken from vendor bios
-(in /sys/class/sound/hwC0D0/init_pin_configs on linux 3.16).
-The sound card configuration on the vendor bios is the same
-as the one on the Lenovo x60.
-
-It improves the default behavior of the sound card:
-- internal microphone is chosen by default
-- when jack is inserted it is chosen instead of internal speaker

-Subject: [PATCH] i945/gma.c use latest linux code to calculate divisors.
-
-The code to compute n, m1, m2, p1 divisors is not correct in coreboot and
-on some targets hits a working mode at lower refresh rate, which is why
-display is working on some targets.
-This patch also fixes reference frequency.
-
-This patch reuses linux code to correctly compute divisors.
-
-The result is that some previously not working displays (Lenovo T60 with
-1024x786, 1400x1050, 2048x1536)
-
-TESTED on T60 with 1024x786.

-Subject: [PATCH] i945/gma.c: generate fake VBT
-
-This generates a fake VBT for the Intel i945 graphic device.
-i945 supports both the mobile chipset 945gm (calistoga)
-and the desktop chipset 945gc (lakeport),
-which is why a VBT with a different id string
-needs to be created for each target.
-
-The VBT id string is obtained from the vbios blob in the following way:
-"strings vbios.bin | grep VBT".

-Subject: [PATCH 1/2] i945/gma.c use latest linux code to calculate divisors.
-
-The code to compute n, m1, m2, p1 divisors is not correct in coreboot and
-on some targets hits a working mode at lower refresh rate, which is why
-display is working on some targets.
-This patch also fixes reference frequency.
-
-This patch reuses linux code to correctly compute divisors.
-
-The result is that some previously not working displays (Lenovo T60 with
-1024x786, 1400x1050, 2048x1536)
-
-TESTED on T60 with 1024x786.

-Subject: [PATCH] i945/gma.c: generate fake VBT
-
-This generates a fake VBT for the Intel i945 graphic device.
-i945 supports both the mobile chipset 945gm (calistoga)
-and the desktop chipset 945gc (lakeport),
-which is why a VBT with a different id string
-needs to be created for each target.
-
-The VBT id string is obtained from the vbios blob in the following way:
-"strings vbios.bin | grep VBT".

-Subject: [PATCH 1/2] x4x/gma.c: Add VESA native resolution mode
-
-This patch implements native resolution, VESA mode, on the VGA output of
-x4x.
-
-It relies on EDID to modeset, but has a fallback-mode (640 x 480 @
-60Hz) if this is no EDID could be found. This fallback mode only works in textmode
-since in VESA mode some payloads (grub2) rely on VBE info, which is being
-generated from an EDID.

-Subject: [PATCH 1/2] gm45/gma.c: use screen on vga connector if connected
-
-The intel x4x and gm45 have very similar integrated graphic devices.
-Currently the x4x native graphic init enables VGA, while gm45 can output
-on LVDS.
-
-This patch reuses the x4x graphic initialisation code
-to enable output on VGA in gm45 in a way that the behavior is similar to vbios:
-If no VGA display is connected the internal LVDS screen is used.
-If an external screen is detected on the VGA port it will be used instead.

-Subject: [PATCH 1/2] gm45/gma.c: use screen on vga connector if connected
-
-The intel x4x and gm45 have very similar integrated graphic devices.
-Currently the x4x native graphic init enables VGA, while gm45 can output
-on LVDS.
-
-This patch reuses the x4x graphic initialisation code
-to enable output on VGA in gm45 in a way that the behavior is similar to vbios:
-If no VGA display is connected the internal LVDS screen is used.
-If an external screen is detected on the VGA port it will be used instead.

-Subject: [PATCH 1/2] gm45/gma.c: use screen on vga connector if connected
-
-The intel x4x and gm45 have very similar integrated graphic devices.
-Currently the x4x native graphic init enables VGA, while gm45 can output
-on LVDS.
-
-This patch reuses the x4x graphic initialisation code
-to enable output on VGA in gm45 in a way that the behavior is similar to vbios:
-If no VGA display is connected the internal LVDS screen is used.
-If an external screen is detected on the VGA port it will be used instead.

-Subject: [PATCH 1/2] gm45/gma.c: use screen on vga connector if connected
-
-The intel x4x and gm45 have very similar integrated graphic devices.
-Currently the x4x native graphic init enables VGA, while gm45 can output
-on LVDS.
-
-This patch reuses the x4x graphic initialisation code
-to enable output on VGA in gm45 in a way that the behavior is similar to vbios:
-If no VGA display is connected the internal LVDS screen is used.
-If an external screen is detected on the VGA port it will be used instead.

-Subject: [PATCH 1/2] gm45/gma.c: use screen on vga connector if connected
-
-The intel x4x and gm45 have very similar integrated graphic devices.
-Currently the x4x native graphic init enables VGA, while gm45 can output
-on LVDS.
-
-This patch reuses the x4x graphic initialisation code
-to enable output on VGA in gm45 in a way that the behavior is similar to vbios:
-If no VGA display is connected the internal LVDS screen is used.
-If an external screen is detected on the VGA port it will be used instead.

-Subject: [PATCH 1/2] gm45/gma.c: use screen on vga connector if connected
-
-The intel x4x and gm45 have very similar integrated graphic devices.
-Currently the x4x native graphic init enables VGA, while gm45 can output
-on LVDS.
-
-This patch reuses the x4x graphic initialisation code
-to enable output on VGA in gm45 in a way that the behavior is similar to vbios:
-If no VGA display is connected the internal LVDS screen is used.
-If an external screen is detected on the VGA port it will be used instead.

-Subject: [PATCH 1/2] gm45/gma.c: use screen on vga connector if connected
-
-The intel x4x and gm45 have very similar integrated graphic devices.
-Currently the x4x native graphic init enables VGA, while gm45 can output
-on LVDS.
-
-This patch reuses the x4x graphic initialisation code
-to enable output on VGA in gm45 in a way that the behavior is similar to vbios:
-If no VGA display is connected the internal LVDS screen is used.
-If an external screen is detected on the VGA port it will be used instead.

-Subject: [PATCH 1/2] gm45/gma.c: use screen on vga connector if connected
-
-The intel x4x and gm45 have very similar integrated graphic devices.
-Currently the x4x native graphic init enables VGA, while gm45 can output
-on LVDS.
-
-This patch reuses the x4x graphic initialisation code
-to enable output on VGA in gm45 in a way that the behavior is similar to vbios:
-If no VGA display is connected the internal LVDS screen is used.
-If an external screen is detected on the VGA port it will be used instead.

-Subject: [PATCH 1/2] gm45/gma.c: use screen on vga connector if connected
-
-The intel x4x and gm45 have very similar integrated graphic devices.
-Currently the x4x native graphic init enables VGA, while gm45 can output
-on LVDS.
-
-This patch reuses the x4x graphic initialisation code
-to enable output on VGA in gm45 in a way that the behavior is similar to vbios:
-If no VGA display is connected the internal LVDS screen is used.

-Subject: [PATCH 1/2] gm45/gma.c: use screen on vga connector if connected
-
-The intel x4x and gm45 have very similar integrated graphic devices.
-Currently the x4x native graphic init enables VGA, while gm45 can output
-on LVDS.
-
-This patch reuses the x4x graphic initialisation code
-to enable output on VGA in gm45 in a way that the behavior is similar to vbios:
-If no VGA display is connected the internal LVDS screen is used.
-If an external screen is detected on the VGA port it will be used instead.

-Subject: [PATCH 1/2] gm45/gma.c: use screen on vga connector if connected
-
-The intel x4x and gm45 have very similar integrated graphic devices.
-Currently the x4x native graphic init enables VGA, while gm45 can output
-on LVDS.
-
-This patch reuses the x4x graphic initialisation code
-to enable output on VGA in gm45 in a way that the behavior is similar to vbios:
-If no VGA display is connected the internal LVDS screen is used.
-If an external screen is detected on the VGA port it will be used instead.

-Subject: [PATCH] nb/intel/gm45: Fix IOMMU
-
-Previously the ME was being reported as present in ACPI
-even when it's firmware was missing. Now we do a check via the pci device
-(HECI) to verify if the ME is there or not.
-
-Note that this test could fail if ME is present but disabled in devicetree,
-but in that case you won't see it in the lspci tree anyway so it shouldn't
-be an issue.

-Subject: [PATCH 1/2] gm45/gma.c: use screen on vga connector if connected
-
-The intel x4x and gm45 have very similar integrated graphic devices.
-Currently the x4x native graphic init enables VGA, while gm45 can output
-on LVDS.
-
-This patch reuses the x4x graphic initialisation code
-to enable output on VGA in gm45 in a way that the behavior is similar to vbios:
-If no VGA display is connected the internal LVDS screen is used.
-If an external screen is detected on the VGA port it will be used instead.
