Julius Werner 3429c77ab0 Add platform-independent coreboot support library This patch adds the foundation for a platform-independent coreboot support library that can be shared by all platforms that boot BL31 from coreboot (acting as BL2). It adds code to parse the "coreboot table", a data structure that coreboot uses to communicate different kinds of information to later-stage firmware and certain OS drivers. As a first small use case for this information, allow platforms to access the serial console configuration used by coreboot, removing the need to hardcode base address and divisors and allowing Trusted Firmware to benefit from coreboot's user configuration (e.g. which UART to pick and which baud rate to use).

This patch adds the foundation for a platform-independent coreboot
support library that can be shared by all platforms that boot BL31 from
coreboot (acting as BL2). It adds code to parse the "coreboot table", a
data structure that coreboot uses to communicate different kinds of
information to later-stage firmware and certain OS drivers.

As a first small use case for this information, allow platforms to
access the serial console configuration used by coreboot, removing the
need to hardcode base address and divisors and allowing Trusted Firmware
to benefit from coreboot's user configuration (e.g. which UART to pick
and which baud rate to use).
