2019-10-25mb/google/{drallion,sarien}: Configure GPIOs in mainboard chip->init()Furquan Shaikh
mainboard_silicon_init_params() is supposed to be used for only overriding any FSP params as per mainboard configuration. GPIOs should be configured by mainboard as part of its chip init(). This ensures proper ordering w.r.t. any common operations that the SoC code might want to perform e.g. snapshot ITSS polarities. This change moves the configuration of GPIOs from mainboard_silicon_init_params() to mainboard chip->init().

2019-10-18mb/google: Shrink GBB section sizeHung-Te Lin
Chrome OS firmware images have moved bitmap resources from GBB into CBFS for a long time, so the GBB should only hold firmware keys and HWID, that is usually less than 10k. ARM boards usually limit GBB to 0x2f00 (see gru, cheza and kukui) but many recent x86 simply copy from old settings and may run out of space when we want to add more resources, for example EC RO software sync. Note, changing the GBB section (inside RO) implies RO update, so this change *must not* be cherry-picked back to old firmware branches if some devices were already shipped.
