2018-11-25nb/intel/i945: Add and use defines for registers of device 0:01.0Elyes HAOUAS

2018-11-25nb/intel/i945/early_init.c: Correct the PEG_LC address of DEV(0:01.0)Elyes HAOUAS
This bug/typo was spoted by Felix Held. As documented in the datasheet, to enable PMEGPE, HPGPE, GENGPE, we need to write 0x7 into DEV(0:01.0) register "PCI Express-G Legacy Control" located at 0xec. Used address at 0x114 to enable GPEs is likely a typo. Patch not tested.

Its spreading copies got out of sync. And as it is not a standard header but used in commonlib code, it belongs into commonlib. While we are at it, always include it via GCC's `-include` switch.

2017-09-20nb/i945/raminit: Use common ddr2 decode functionsArthur Heymans
This simplifies computing dram timings a lot. This removes computation of rank size based on columns, rows, banks,... and uses the information in SPD byte 31. The result of this is that dimms with multiple asymmetric ranks are not supported anymore. These however are very rare and most likely never tested on this platform. This also uses i2c block read instead of byte read to speed up the raminit. The result is less time is being spend reading SPDs. It still keeps smbus read byte as a backup if i2c block read were to fail.

Vendor BIOS leaves UPMC1 untouched (on 945gc the default is 0x0203). Not running PCIEx16 init which is valid for 945gm seems to fix all issues and instabilities related to the PEG port. According to lspci the link width is at the desired x16. It is unknown if devices requesting a lower width work automatically or need more configuration. What happens is that IGD gets disabled by the disable function in gma.c when an external GPU is found unless CONFIG_ONBOARD_VGA_IS_PRIMARY is set. Setting IGD as secondary makes Linux (4.10) hang, so this behavior is a requirement for now. TESTED on P5GC-MX with a discrete GPU and both CONFIG_ONBOARD_VGA_IS_PRIMARY set and unset.

This reuses some of gm45 code to set up the panel. Panel start and stop delays and pwm frequency can now be set in devicetree. Linux does not make the difference between 945gm and gm45 for panel delays, so it is safe to assume the semantics of those registers are the same. The core display clock is computed according to "Mobile Intel® 945 Express Chipset Family" Datasheet. This selects Legacy backlight mode since most targets have some smm code that rely on this. This sets the same backlight frequency as vendor bios on Thinkpad X60 and T60. A default of 180Hz is selected for the PWM frequency if it is not defined in the devicetree, this might be annoying for displays that are LED backlit, but is a safe value for CCFL backlit displays.

The code to set the igd frequencies is written with the mobile version of the 945 chipset in mind and seems to cause cause strange igd related problems on the desktop versions.

A fix is to hardcode the core display and render clocks to their maximum, potentially also improving graphical performance.

2016-12-07PCI ops: MMCONF_SUPPORT_DEFAULT is requiredKyösti Mälkki
Doing PCI config operations via MMIO window by default is a requirement, if supported by the platform. This means chipset or CPU code must enable MMCONF operations early in bootblock already, or before platform-specific romstage entry. Platforms are allowed to have NO_MMCONF_SUPPORT only in the case it is actually not implemented in the silicon.
