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.

2016-01-31arm: Replace test for CONFIG_ARMV7 with CONFIG_CPU_V7Marek Vasut
The arch/arm/lib/cache-cp15.c checks for CONFIG_ARMV7 and if this macro is set, it configures TTBR0 register. This register must be configured for the cache on ARMv7 to operate correctly. The problem is that noone actually sets the CONFIG_ARMV7 macro and thus the TTBR0 is not configured at all. On SoCFPGA, this produces all sorts of minor issues which are hard to replicate, for example certain USB sticks are not detected or QSPI NOR sometimes fails to write pages completely. The solution is to replace CONFIG_ARMV7 test with CONFIG_CPU_V7 one. This is correct because the code which added the test(s) for CONFIG_ARMV7 was added shortly after CONFIG_ARMV7 was replaced by CONFIG_CPU_V7 and this code was not adjusted correctly to reflect that change.

2016-01-27secure_boot: split the secure boot functionality in two partsAneesh Bansal
There are two phases in Secure Boot 1. ISBC: In BootROM, validate the BootLoader (U-Boot). 2. ESBC: In U-Boot, continuing the Chain of Trust by validating and booting LINUX. For ESBC phase, there is no difference in SoC's based on ARM or PowerPC cores. But the exit conditions after ISBC phase i.e. entry conditions for U-Boot are different for ARM and PowerPC. PowerPC: If Secure Boot is executed, a separate U-Boot target is required which must be compiled with a diffrent Text Base as compared to Non-Secure Boot. There are some LAW and TLB settings which are required specifically for Secure Boot scenario. ARM: ARM based SoC's have a fixed memory map and exit conditions from BootROM are same irrespective of boot mode (Secure or Non-Secure). Thus the current Secure Boot functionlity has been split into two parts: CONFIG_CHAIN_OF_TRUST This will have the following functionality as part of U-Boot: 1. Enable commands like esbc_validate, esbc_halt 2. Change the environment settings based on bootmode, determined at run time: - If bootmode is non-secure, no change - If bootmode is secure, set the following: - bootdelay = 0 (Don't give boot prompt) - bootcmd = Validate and execute the bootscript. CONFIG_SECURE_BOOT This is defined only for creating a different compile time target for secure boot. Traditionally, both these functionalities were defined under CONFIG_SECURE_BOOT. This patch is aimed at removing the requirement for a separate Secure Boot target for ARM based SoC's. CONFIG_CHAIN_OF_TRUST will be defined and boot mode will be determine at run time. Another Security Requirement for running CHAIN_OF_TRUST is that U-Boot environemnt must not be picked from flash/external memory. This cannot be done based on bootmode at run time in current U-Boot architecture. Once this dependency is resolved, no separate SECURE_BOOT target will be required for ARM based SoC's. Currently, the only code under CONFIG_SECURE_BOOT for ARM SoC's is defining CONFIG_ENV_IS_NOWHERE Signed-off-by: Aneesh Bansal <aneesh.bansal@nxp.com> Acked-by: Ruchika Gupta <ruchika.gupta@nxp.com> Reviewed-by: York Sun <york.sun@nxp.com>
