mb/google/poppy: Nami - invoke power cycle of FPMCU on startup
Add functionality such that the FPMCU is power cycled long enough on boot to ensure proper reset. This solution relies solely on coreboot to sequence the power and reset signals appropriately (150ms on boot). BUG=b:245954151 TEST=Confirmed FPMCU is still functional on Nami. Confirmed power is off for 150ms seconds on boot. Confirmed RCC_CSR of FPMCU indicates power cycle occurred. Confirmed reset is de-asserted approx 3ms after power application (target >2.5ms) Change-Id: I21eb85dc11e0ea0eb5de8a6092b01663d3c3df91 Signed-off-by: Tarun Tuli <taruntuli@google.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/68820 Reviewed-by: Subrata Banik <subratabanik@google.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Eric Lai <eric_lai@quanta.corp-partner.google.com>
