2017-11-25Silicon/NXP: add RTC support library for PCF8563 I2C IPArd Biesheuvel
Add a RealTimeClockLib implementation for the NXP PCF8563 as used on the Socionext Developer Box board. Note that the standard I2C protocol stack does not support runtime use, so this driver invokes the I2C master protocol directly. This requires support from the platform side as well, and so this driver will only attach to a I2C master that has the gPcf8563RealTimeClockLibI2cMasterProtolGuid protocol installed on its handle. It is up to the platform to ensure that the driver producing the I2C master protocol in question is runtime capable, and is not shared with the I2C protocol stack (i.e., it should not have the I2C Bus Configuration Management protocol installed as well).

2017-11-17Silicon/SynQuacerMemoryInitPeiLib: ignore capsules when clearing NVRAMArd Biesheuvel
In preparation of adding support for setting a DIP switch to clear the EFI variable store, update the early capsule handling logic to take the boot mode into account. This is necessary for two reasons: - we override the boot mode when a capsule is detected, - the capsule detection itself involves reading a EFI variable, which we shouldn't be doing if the varstore may be in a bad state. So factor out the initial capsule check (to keep the code understandable) and only perform it if we are not booting in 'clear NVRAM' mode.
