2021-09-08cpu/x86/tsc: Deduplicate Makefile logicAngel Pons
The code under `cpu/x86/tsc` is only compiled in when its `Makefile.inc` is included from platform (CPU/SoC) code and the `UDELAY_TSC` Kconfig option is enabled. Include `cpu/x86/tsc/Makefile.inc` once from `cpu/x86/Makefile.inc` and drop the now-redundant inclusions from platform code. Also, deduplicate the `UDELAY_TSC` guards.

2021-09-08soc/{apl,glk}: Allow to select the primary graphics deviceMaxim Polyakov
Allow to select the primary graphics device between the IGD and the external PCIe GPU depending on the ONBOARD_VGA_IS_PRIMARY config. The option sets the priority only. This means that if a high priority is set for an external PCI device and it is not connected/not enabled, then the device with a lower priority will be used, in our case it is IGD. TEST = Set PRIMARY_PCI and boot Linux on the Kontron mAL10 [1] with the miniPCIe video adapter on the Silicon Motion SM750 controller. As a result, the display connected to an external GPU device shows the Tianocore logo + setup menu and the desktop.

2021-09-08soc/amd/common/block/i2c: use common GPIO API in drive_sclFelix Held
No need to do raw GPIO MMIO accesses when basically the same functionality can be achieved by using existing APIs. Using the existing GPIO API instead of raw GPIO MMIO register accesses allows containing all direct GPIO MMIO accesses inside the common AMD GPIO code which will be done in subsequent patches. Since the value parameter of gpio_set is int, change the type of the val parameter of drive_scl to int as well even though I'm not sure why a signed integer was used for this in the common GPIO API. Since program_gpios already configures the SCL GPIOs as outputs, gpio_set can be used in drive_scl which only sets the output value, but doesn't configure the direction. TEST=The waveform on the SCL pin of I2C3 on a barla/careena Chromebook looks similar to the same as before during the reset_i2c_peripherals call, but due to the additional overhead of the read-modify-write to the GPIO register instead of just a write, the pulse width gets about 50% longer. Since the udelay call in drive_scl still has an open TODO to make this configurable and the pulses being longer is in the safe side, this side-effect can be addressed in a follow-up patch.

2021-09-08soc/amd/*/bootblock,early_fch: rework i2c_scl_pins configurationFelix Held
drive_scl in soc/amd/common/block/i2c/i2c.c writes the raw GPIO MMIO configuration register and drives it as output, so don't initially configure the GPIO as input with no pull up/down. This is a preparation to use the common AMD GPIO access functions instead of the raw register accesses, since the gpio_set function only sets the output value, but doesn't reconfigure the direction. Using gpio_output there instead would reconfigure the direction as well, but would result in doubling the number of MMIO accesses, so just configure the GPIOs correctly right away to avoid that. TEST=The waveform on the SCL pin of I2C3 on a barla/careena Chromebook looks exactly the same as before during the reset_i2c_peripherals call. This was probed at the SCL pad of the unpopulated I2C level shifter on the side that is connected to the SoC.

2021-08-27soc/amd/common/fsp/fsp_validate: add runtime check for FSP-M binary sizeFelix Held
When modules are added to the FSP and they won't fit into the FSP binary any more, the size can be increased in the FSP build. Especially in the case of debug builds the increased size might not fit into the memory region it gets decompressed into which starts at FSP_M_ADDR and has a size of FSP_M_SIZE. SoCs can implement the soc_validate_fspm_header function that ends up being called by the FSP driver in romstage to do some additional checks on the FSP binary's header that includes the version number and the image size. We can use the image size field to check if it fits into the reserved region. Since the FSP-M memory region is located after romstage loading it won't clobber the romstage code where we do the check. This runtime check is added in addition to the build-time check to also cover the case when the FSP binaries in CBFS get replaced with ones that don't fit into the reserved memory region after the coreboot build. BUG=b:186149011 TEST=Mandolin still boots fine with the patch applied. When as a test the FSP_M_SIZE Kconfig option in soc/amd/picasso is decreased to 0x10000 which is by far not enough for the decompressed FSP-M binary to fit into it prints the newly added error message on the console and then stops.

2021-08-20qualcomm/sc7180: Switch to common MIPI panel libraryJulius Werner
This patch changes the sc7180 boards to use the new common MIPI panel framework, which allows more flexible initialization command packing and sharing panel definitions between boards. (I'm taking the lane count control back out again for now, since it seems we only ever want 4 for now anyway, and if we ever have a need for a different lane count it's not clear whether that should be a property of the board or the panel or both. Better to leave that decision until we have a real use case.) Also, the code was not written to deal with DCS commands that were not a length divisible by 4 (it would read over the end of the command buffer). The corresponding kernel driver seems to pad the command with 0xff instead, let's do the same here. (Also increase the maximum allowed command length to 256 bytes, as per Qualcomm's recommendation.)

2021-08-18soc/amd/cezanne: Disable Co-op multitaskingRaul E Rangel
There are gremlins in the system. thread_coop_enable has an assert. This is currently problematic for two reasons. assert(current->can_yield <= 0); When doing smm_do_relocate we are entering a deadlock. The root cause hasn't been quite found yet, but it's related to co-op multi-threading. For some reason the assert in thread_coop_enable is firing when releasing the console_lock spin lock. I'm assuming cpu_info hasn't been initialized yet. The assert tries to perform a printk, but since the console_lock is still held we end up in a dead lock. This dead lock will generally not happen after a warm reset. Again I'm assuming because the cpu_info struct has some valid values at this point. For now disable multi-tasking until we fix the cpu_info initialization.

2021-08-18device: Move MIPI panel library from mainboard/google/kukui into commonJulius Werner
All boards that are trying to use MIPI panels eventually run into the problem that they need to store physical parameters and a list of DCS initialization commands for each panel, and these commands can be very different (e.g. a large amount of very short commands, a few very large commands, etc.). Finding a data format to fit all these different cases efficiently into the same structures keeps being a challenge, and the Kukui mainboard already once put a lot of effort into designing a clean, flexible and efficient solution for this. This patch moves that framework into a common src/device/mipi/ library where it can be used by other boards as well. (Also, this will hopefully allow us to save some duplicated work when using the same panel on different boards at some point.)
