| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current AM57xx evm supports both BeagleBoard-X15 (http://beagleboard.org/x15) and AM57xx EVM (http://www.ti.com/tool/tmdxevm5728). The AM572x EValuation Module(EVM) provides an affordable platform to quickly start evaluation of Sitara. ARM Cortex-A15 AM57x Processors (AM5728, AM5726, AM5718, AM5716) and accelerate development for HMI, machine vision, networking, medical imaging and many other industrial applications. This EVM is based on the same BeagleBoard-X15 Chassis and adds mPCIe, mSATA, LCD, touchscreen, Camera, push button and TI's wlink8 offering. Since the EEPROM contents are compatible between the BeagleBoard-X15 and the AM57xx-evm, we add support for the detection logic to enable support for various user programmable scripting capability. NOTE: U-boot configuration is currently a superset of AM57xx evm and BeagleBoard-X15 and no additional configuration tweaking is needed. This change also sets up the stage for future support of TI AM57xx EVMs to the same base bootloader build.

* | ARM: OMAP4/5: Centralize early clock initializationKipisz, Steven2016-03-14-4/+20
|/ | | | | | | | | | | | | | | | | | | | | | | | | | 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.

We will have a risk that, if A7 enter wait, M4 enter stop, peripheral will have chance to get ipg_stop and ipg_wait asserted same time. Also if M4 enters stop mode, A7 will have no chance to access the peripheral. There are 26 peripherals affected by this IC issue: SIM2(sim2/emvsim2) SIM1(sim1/emvsim1) UART1/UART2/UART3/UART4/UART5/UART6/UART7 SAI1/SAI2/SAI3 WDOG1/WDOG2/WDOG3/WDOG4 GPT1/GPT2/GPT3/GPT4 PWM1/PWM2/PWM3/PWM4 ENET1/ENET2 Software Workaround: The solution is to set the peripherals to Domain0 by A core, since A core in Domain0. The peripherals which will be used by M4, will be set to Domain1 by M4. For example, A core set WDOG4 to domain0, but when M4 boots up, M4 will set WDOG4 to domain1, because M4 will use WDOG4. So the peripherals are not shared by them. This way requires the uboot implemented the RDC driver and set the 26 IPs above to domain 0 only. M4 image will set the M4 to domain 1 and set peripheral which it will use to domain 1. This patch enables the CONFIG_IMX_RDC and CONFIG_IMX_BOOTAUX for i.MX7D SABRESD board, and setup the 26 IP resources to domain 0.
