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.

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.

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.

Add a new Kconfig option to enable or disable the 4 DWORD burst support of the SPI controller and use this setting to determine if the corresponding feature bit in SPI100_HOST_PREF_CONFIG will be set or cleared. Since fch_spi_disable_4dw_burst can now enable or disable the feature, rename it to fch_spi_configure_4dw_burst.

There is no support for using the 32 bit binaryPI with a 64 bit coreboot while there is code to use a 32 bit FSP with 64 bit coreboot, so not building this for FSP-based SoC support moves us one step closer to be able to build coreboot as 64 bit binary for Picasso and Cezanne.
