MvEeprom driver produces EFI_EEPROM_PROTOCOL, which can be used by other drivers or applications. Working EFI_I2C_IO_PROTOCOL is required by driver to operate.
EEPROM devices' addresses need to be fed via 'PcdEepromI2cAddresses'.

Introduction +--------------- +**MvEeprom** driver creates EFI_EEPROM_PROTOCOL, which ++is used for managing eeprom. + +2. MvEeprom driver design +------------------------- +Every I2C device driver should implement EFI_DRIVER_BINDING_PROTOCOL and +consume EFI_I2C_IO_PROTOCOL for transactions on I2C bus. MvEeprom driver +additionally implements EFI_EEPROM_PROTOCOL. + + 2.1 EFI_DRIVER_BINDING_PROTOCOL + ------------------------------- + Driver Binding protocol is extensively covered in UEFI documentation, as + it is not specific to I2C stack. The only difference is that Supported() + function should check if EFI_I2C_IO_PROTOCOL provides valid EFI_GUID value. + Excerpt from MvEepromSupported(): + + Status = gBS->OpenProtocol ( + ControllerHandle, + &gEfiI2cIoProtocolGuid, + (VOID **) &TmpI2cIo, + gImageHandle, + ControllerHandle, + EFI_OPEN_PROTOCOL_BY_DRIVER + ); + if (EFI_ERROR(Status)) { + return EFI_UNSUPPORTED; + } + + /* get EEPROM devices' addresses from PCD */ + EepromAddresses = PcdGetPtr (PcdEepromI2cAddresses); + if (EepromAddresses == 0) { + Status = EFI_UNSUPPORTED; + goto out; + } + + Status = EFI_UNSUPPORTED; + for (i = 0; EepromAddresses[i] != '\0'; i++) { + /* last byte of GUID contains address on I2C bus */ + EepromGuid.Data4[7] = EepromAddresses[i]; + if (CompareGuid(TmpI2cIo->DeviceGuid, &EepromGuid)) { + DEBUG((DEBUG_INFO, "A8kEepromSupported: offered GUID fits desired\n")); + Status = EFI_SUCCESS; + break; + } + } + + 2.2 EFI_I2C_IO_PROTOCOL + ----------------------- + This protocol is provided by generic I2C stack. Multiple drivers can use IO + protocol at once, as queueing is implemented. + + QueueRequest is a routine that queues an I2C transaction to the I2C + controller for execution on the I2C bus. + + 2.3 EFI_EEPROM_PROTOCOL + ----------------------- + typedef struct _EFI_EEPROM_PROTOCOL EFI_EEPROM_PROTOCOL; + + #define EEPROM_READ 0x1 + #define EEPROM_WRITE 0x0 + typedef + EFI_STATUS + (EFIAPI *EFI_EEPROM_TRANSFER) ( + IN CONST EFI_EEPROM_PROTOCOL *This, + IN UINT16 Address, + IN UINT32 Length, + IN UINT8 *Buffer, + IN UINT8 Operation + ); + + struct _EFI_EEPROM_PROTOCOL { + EFI_EEPROM_TRANSFER Transfer; + UINT8 Identifier; + }; + +3. Adding new I2C slave device drivers +-------------------------------------- +In order to support I2C slave device other than EEPROM, new driver should +be created. Required steps follow. + + 1. Create driver directory (OpenPlatformPkg/Drivers/I2c/Devices/...). + 2. Create stubs of .inf and .c files (MvEeprom files are a reference), + include .inf file in platform .dsc and .fdf files. + 3. Implement EFI_DRIVER_BINDING_PROTOCOL - Start(), Stop(), Supported() + functions' implementation is a must. EFI_DRIVER_BINDING_PROTOCOL + should be installed at driver's entry point. + 4. Add I2C address of device to PcdI2cSlaveAddresses in .dsc file. + 5. Test available EFI_I2C_IO_PROTOCOLs in Supported() - find instance + with valid GUID (consisting of I2C_GUID and slave I2C address). + 6. Open EFI_I2C_IO_PROTOCOL for usage in Start(). After that, QueueRequest + function should be available. + 7. Implement core functionality of driver (using QueueRequest to access I2C). + 8. (not mandatory) Produce/consume additional protocols. diff --git a/Drivers/I2c/Devices/MvEeprom/MvEeprom.c b/Drivers/I2c/Devices/MvEeprom/MvEeprom.c new file mode 100644 index 0000000..2b0d191 --- /dev/null +++ b/Drivers/I2c/Devices/MvEeprom/MvEeprom.c @@ -0,0 +1,292 @@ +/******************************************************************************** +Copyright (C) 2016 Marvell International Ltd. + +Marvell BSD License Option + +If you received this File from Marvell, you may opt to use, redistribute and/or +modify this File under the following licensing terms. +Redistribution and use in source and binary forms, with or without modification, +are permitted provided that the following conditions are met: + +* Redistributions of source code must retain the above copyright notice, + this list of conditions and the following disclaimer. + +* Redistributions in binary form must reproduce the above copyright + notice, this list of conditions and the following disclaimer in the + documentation and/or other materials provided with the distribution. + +* Neither the name of Marvell nor the names of its contributors may be + used to endorse or promote products derived from this software without + specific prior written permission. + +THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS "AS IS" AND +ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED +WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE ARE +DISCLAIMED.
