Drivers/I2c: Create MvI2cDxe driver
MvI2cDxe driver was adapted to generic UEFI I2C stack. Connection with
following interfaces was required:
- EFI_I2C_MASTER_PROTOCOL
- EFI_I2C_BUS_CONFIGURATION_MANAGEMENT_PROTOCOL
- EFI_I2C_ENUMERATE_PROTOCOL
Driver exports configuration options via PCDs. Configurable options
include:
- PcdI2cSlaveAddresses - should contain a list of valid I2C devices'
addresses on bus
- PcdI2cBaseAddresses - physical address of I2C controller registers
- PcdI2cClockFrequency - I2c clock frequency on platform
Drivers of devices on I2C bus should never use EFI_I2C_MASTER_PROTOCOL
directly. Instead, these ought to utilise EFI_I2C_IO_PROTOCOL produced
by generic UEFI stack.
