* soc/amd: make configure_espi_with_mb_hook call conditionalFelix Held2021-10-151-2/+6
| | | | | | | | | | | | | If a system doesn't use eSPI or has the eSPI interface already configured in verstage on PSP, not calling configure_espi_with_mb_hook from fch_pre_init makes it a bit more obvious that the eSPI interface initialization will be skipped.

| | | | | | | | | | | | | | | | | | | eSPI is setup in two different locations in bootblock depending on early port80 routing configuration. Also eSPI is setup in PSP, if verified boot starts before bootblock. Consolidate all the scenarios by initializating eSPI very early in fch_pre_init if verified boot starts after bootblock and eSPI is enabled. BUG=None TEST=Build and boot to OS in Guybrush.

* soc/amd/*/bootblock,early_fch: rework i2c_scl_pins configurationFelix Held2021-09-081-5/+5
| | | | | | | | | | | | | | | | | | | | | | | 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.
