2021-10-26cpu/x86: Introduce and use `CPU_X86_LAPIC`Felix Held
With using a Kconfig option to add the x86 LAPIC support code to the build, there's no need for adding the corresponding directory to subdirs in the CPU/SoC Makefile. Comparing which CPU/SoC Makefiles added (cpu/)x86/mtrr and (cpu/)x86/lapic before this and the corresponding MTRR code selection patch and having verified that all platforms added the MTRR code on that patch shows that soc/example/min86 and soc/intel/quark are the only platforms that don't end up selecting the LAPIC code. So for now the default value of CPU_X86_LAPIC is chosen as y which gets overridden to n in the Kconfig of the two SoCs mentioned above.

2021-10-25cpu,soc/x86: always include cpu/x86/mtrr on x86 CPUs/SoCsFelix Held
All x86-based CPUs and SoCs in the coreboot tree end up including the Makefile in cpu/x86/mtrr, so include this directly in the Makefile in cpu/x86 to add it for all x86 CPUs/SoCs. In the unlikely case that a new x86 CPU/SoC will be added, a CPU_X86_MTRR Kconfig option that is selected be default could be added and the new CPU/SoC without MTRR support can override this option that then will be used in the Makefile to guard adding the Makefile from the cpu/x86/mtrr sub-directory. In cpu/intel all models except model 2065X and 206AX are selcted by a socket and rely on the socket's Makefile.inc to add x86/mtrr to the subdirs, so those models don't add x86/mtrr themselves. The Intel Broadwell SoC selects CPU_INTEL_HASWELL and which added x86/mtrr to the subdirs. The Intel Xeon SP SoC directory contains two sub-folders for different versions or generations which both add x86/mtrr to the subdirs in their Makefiles.

For coreboot proper, I/O APIC programming is not really required, except for the APIC ID field. We generally do not guard the related set_ioapic_id() or setup_ioapic() calls with CONFIG(IOAPIC).

2021-10-22cpu/x86/mp_init: move printing of failure message into mp_init_with_smmFelix Held
Each CPU/SoC checks the return value of the mp_init_with_smm and prints the same error message if it wasn't successful, so move this check and printk to mp_init_with_smm. For this the original mp_init_with_smm function gets renamed to do_mp_init_with_smm and a new mp_init_with_smm function is created which then calls do_mp_init_with_smm, prints the error if it didn't return CB_SUCCESS and passes the return value of do_mp_init_with_smm to its caller. Since no CPU/SoC code handles a mp_init_with_smm failure apart from printing a message, also add a comment at the mp_init_with_smm call sites that the code might want to handle a failure.

Some AMD SoCs have a 5th GPIO bank, the remote GPIO bank, which isn't located right after the 4th GPIO bank, but instead at a different location inside the APCIMMIO region. A difference to the first 4 GPIO banks is that the corresponding GPIO MUX registers aren't in a separate bank, but at the end of the remote GPIO region. So this remote GPIO region only supports 48 GPIOs with a 32 bit configuration register each and has the 8 bit GPIO MUX registers beginning at offset 0xc0 in the remote GPIO region. For now using the remote GPIOs from verstage on PSP isn't supported.

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.

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.

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.
