This CL should be broken down into multiple smaller CLs:
- Adding probed property to sconfig to support probed devices
- Adding power resource device to device tree
- Adding power resource driver for ACPI
- Adding helper function for enabling power in bootblock
- Moving all mainboards using power resource to the newly added device
- Get rid of power resource properties from I2C generic and SPI devices.
- Get rid of probed property
If power is enabled in bootblock, and probing is done in ramstage, when is the appropriate time to deassert reset?
I think typically it is the reset time which is longer? i.e. enable time is typically 1 or 2ms I believe? If that is correct, then I would expect reset to be de-asserted in bootblock too.
