2016-03-14ARM: omap-common: Add standard access for board description EEPROMLokesh Vutla
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.

2016-03-14ARM: OMAP4/5: Centralize early clock initializationKipisz, Steven
Early clock initialization is currently done in two stages for OMAP4/5 SoCs. The first stage is the initialization of console clocks and then we initialize basic clocks for functionality necessary for SoC initialization and basic board functionality. By splitting up prcm_init and centralizing this clock initialization, we setup the code for follow on patches that can do board specific initialization such as board detection which will depend on these basic clocks. As part of this change, since the early clock initialization is centralized, we no longer need to expose the console clock initialization. NOTE: we change the sequence slightly by initializing console clocks timer after the io settings are complete, but this is not expected to have any functioanlity impact since we setup the basic IO drive strength initialization as part of do_io_settings.

2016-03-14Kconfig: Move CONFIG_FIT and related options to KconfigSimon Glass
There are already two FIT options in Kconfig but the CONFIG options are still in the header files. We need to do a proper move to fix this. Move these options to Kconfig and tidy up board configuration: CONFIG_FIT CONFIG_OF_BOARD_SETUP CONFIG_OF_SYSTEM_SETUP CONFIG_FIT_SIGNATURE CONFIG_FIT_BEST_MATCH CONFIG_FIT_VERBOSE CONFIG_OF_STDOUT_VIA_ALIAS CONFIG_RSA Unfortunately the first one is a little complicated. We need to make sure this option is not enabled in SPL by this change. Also this option is enabled automatically in the host builds by defining CONFIG_FIT in the image.h file. To solve this, add a new IMAGE_USE_FIT #define which can be used in files that are built on the host but must also build for U-Boot and SPL. Note: Masahiro's moveconfig.py script is amazing.

2016-02-29ARM: uniphier: refactor UMC init code for ProXstream2Masahiro Yamada
Currently, a dummy value is defined for the UMC_SPCCTLA register when the DRAM size is zero. This seems weird because the controller does not need setting in the first place if the size is zero. Also, redefine enum dram_size to represent the DRAM size per 16-bit unit. This makes things simpler because the channel 0 and 1 are connected with 32-bit width DRAM, while the channel 2 is connected with 16-bit width one. I am renaming SIZE_* into DRAM_SZ_* (and also FREQ_* to DRAM_FREQ_* for consistency) while I am here because SIZE_* might be easily mixed-up with the macros in include/linux/sizes.h.
