2019-12-14Revert "{northbridge,soc,southbridge}: Don't use both of _ADR and _HID"Nico Huber
This reverts commit 01787608670adec26fcea48173e18395e51c790e. AMD: Dropping the _HID of PCI root bus doesn't work well and people started to notice the breakage. Intel: These platforms have a devicetree switch to choose between PCI and ACPI modes. In the former case we need _ADR, but in the latter _HID as the PCI devices are hidden. The conflicting use of _ADR and _HID still needs to be fixed before we can bump our IASL version.

2019-11-03cpu/x86/tsc: Flip and rename TSC_CONSTANT_RATE to UNKNOWN_TSC_RATEKyösti Mälkki
The x86 timers are a bit of a mess. Cases where different stages use different counters and timestamps use different counters from udelays. The original intention was to only flip TSC_CONSTANT_RATE Kconfig to NOT_CONSTANT_TSC_RATE. The name would be incorrect though, those counters do run with a constant rate but we just lack tsc_freq_mhz() implementation for three platforms. Note that for boards with UNKNOWN_TSC_RATE=y, each stage will have a slow run of calibrate_tsc_with_pit(). This is easy enough to fix with followup implementation of tsc_freq_mhz() for the platforms. Implementations with LAPIC_MONOTONIC_TIMER typically will not have tsc_freq_mhz() implemented and default to UNKNOWN_TSC_RATE. However, as they don't use TSC for udelay() the slow calibrate_tsc_with_pit() is avoided. Because x86/tsc_delay.tsc was using two different guards and nb/via/vx900 claimed UDELAY_TSC, but pulled UDELAY_IO implementation, we also switch that romstage to use UDELAY_TSC.

2019-10-16intel/broadwell: Implement proper backlight PWM configNico Huber
Port the backlight-PWM handling from Skylake instead of the previously used Haswell version. We use a 200Hz PWM signal for all boards. Which is higher than the previous devicetree value, 183Hz, but that was over- ridden by the VBIOS anyway. 200Hz is still very low, considering LED backlights, but accurate values are unknown at this time. Lynx Point, the PCH for Haswell and Broadwell, is a transition point for the backlight-PWM config. On platforms with a PCH, we have: o Before Lynx Point: The CPU has no PWM pin and sends the PWM duty-cycle setting to the PCH. The PCH can choose to ignore that and use its own setting (BLM_PCH_OVERRIDE_ENABLE). We use the CPU setting on these platforms. o Lynx Point + Haswell: The CPU has an additional PWM pin but can be set up to send its setting to the PCH as before. The PCH can still choose to ignore that. We use the CPU setting with Haswell. o Lynx Point + Broadwell: The CPU can't send its setting to the PCH anymore. BLM_PCH_ OVERRIDE_ENABLE must always be set(!) if the PCH PWM pin is used (it virtually always is). We have to use the PCH setting in this case. o After Lynx Point: Same as with Broadwell, only BLM_PCH_OVERRIDE_ENABLE is implied and the bit not implemented anymore.

2019-08-20src: Remove variable length arraysJacob Garber
Variable length arrays were a feature added in C99 that allows the length of an array to be determined at runtime. Eg. int sum(size_t n) { int arr[n]; ... } This adds a small amount of runtime overhead, but is also very dangerous, since it allows use of an unlimited amount of stack memory, potentially leading to stack overflow. This is only worsened in coreboot, which often has very little stack space to begin with. Citing concerns like this, all instances of VLA's were recently removed from the Linux kernel. In the immortal words of Linus Torvalds [0], AND USING VLA'S IS ACTIVELY STUPID! It generates much more code, and much _slower_ code (and more fragile code), than just using a fixed key size would have done. [...] Anyway, some of these are definitely easy to just fix, and using VLA's is actively bad not just for security worries, but simply because VLA's are a really horribly bad idea in general in the kernel. This patch follows suit and zaps all VLA's in coreboot. Some of the existing VLA's are accidental ones, and all but one can be replaced with small fixed-size buffers. The single tricky exception is in the SPI controller interface, which will require a rewrite of old drivers to remove [1].

As of CL:1605641, vboot2 code should be used for setting and checking display init state. Remove all vboot1 OPROM-related code, and use the vboot2 display init code which has already been added in previous commits. coreboot should not be reading vboot NVRAM flags directly. Remove the function vboot_wants_oprom(), and instead rely on display_init_required(), which uses the VBOOT_WD_FLAG_DISPLAY_INIT value stored in vboot_working_data.flags, initialized during verstage. Note that this means in the case of CONFIG_VBOOT=y, the return value of display_init_required() can only be trusted after verstage has been executed. This should not be a problem assuming that all display initialization occurs in ramstage.

This patch fixes up all code that would throw a -Wtype-limits warning.

The name OPROM is somewhat inaccurate, since other steps to bring up display and graphics are needed depending on mainboard/SoC.

2019-04-01vboot: Select CONFIG_VBOOT_OPROM_MATTERS in more casesJulius Werner
This patch enables CONFIG_VBOOT_OPROM_MATTERS in a few more cases where I think(?) it should be. Haswell, Broadwell and Baytrail Chromebooks have this enabled in their old depthcharge firmware branches -- we presumably just forgot to move it over when vboot2 migrated the option to coreboot. Braswell didn't, but it seems like this requirement was added when it was migrated to FSP 1.1...? (Not very sure about that one, but it does call load_vbt() right now which executes things based on display_init_required().) Additionally, it seems to make sense to enable it whenever the user explicitly selects VGA_ROM_RUN in menuconfig (like one of the Intel defconfigs does). Once we have all this, one could take a step back and ask whether this option still makes sense at all anymore. It's enabled for almost all devices (that work with vboot at all), it will presumably be enabled for all future devices, and it seems that most devices that don't enable it use libgfxinit, which as far as I can tell isn't gated on display_init_required() but probably should be. Realistically, whatever kind of display init a board needs to do (native or option ROM), it's probably expensive enough that it's worth skipping on a normal mode vboot boot, and we'd want to have this enabled by default on everything except boards that actually don't have a display. So maybe we should flip it around to CONFIG_VBOOT_OPROM_DOESNT_MATTER, but doing that would probably lead to nobody ever selecting it at all. Not sure what the best solution there is yet, but I think this patch at least moves things in the more correct direction.
