General-purpose I/O (GPIO) module is integrated on chip.
In general, the GPIO module supports up to 32 general-purpose
I/O ports. Each port can be configured as an input or as an
output. However, some implementations may restrict specific ports to
input-only, output-only, or reserved (unimplemented).

This patch set adds GPIO Library.
Gpio Library is required to set muxing to enable USB controller.
Changes in v3:
- Incorporated review comments
Changes in v2:
- Modified GpioLib as per review comments
- Prepared separate patch for SCFG enablement
- Prepared sepaarte patch for USB errata implementation
Meenakshi Aggarwal (6):
Silicon/NXP: Add GPIO Library support.
Platform/NXP/LS1046aFrwyPkg: MUX changes for USB
Silicon/NXP: Add SCFG support for Chassis2
Silicon/NXP: Implement USB Errata Workarounds
Silicon/NXP/LS1046A: Apply USB errata workarounds
LS1046aFrwy: Enable USB support for LS1046AFRWY board.
