ARM: omap-common: Add standard access for board description EEPROM Several TI EVMs have EEPROM that can contain board description information such as revision, DDR definition, serial number, etc. In just about all cases, these EEPROM are on the I2C bus and provides us the opportunity to centralize the generic operations involved. The on-board EEPROM on the BeagleBone Black, BeagleBone, AM335x EVM, AM43x GP EVM, AM57xx-evm, BeagleBoard-X15 share the same format. However, DRA-7* EVMs, OMAP4SDP use a modified format. We hence introduce logic which is generic between these platforms without enforcing any specific format. This allows the boards to use the relevant format for operations that they might choose. This module will compile for all TI SoC based boards when CONFIG_TI_I2C_BOARD_DETECT is enabled to have optimal build times for platforms that require this support. It is important to note that this logic is fundamental to the board configuration process such as DDR configuration which is needed in SPL, hence cannot be part of the standard u-boot driver model (which is available later in the process). Hence, to aid efficiency, the eeprom contents are copied over to SRAM scratchpad memory area at the first invocation to retrieve data. To prevent churn with cases such as DRA7, where eeprom format maybe incompatible, we introduce a generic common format in eeprom which is made available over accessor functions for usage. Special handling for BBG1 EEPROM had to be introduced thanks to the weird eeprom rev contents used. The follow on patches introduce the use of this library for AM335x, AM437x, and AM57xx.
