* board: AM335x-ICEv2: Add cpsw supportLokesh Vutla2016-05-27-7/+80
| | | | | | | | | | | | | | | | | | | | | | In order to enable cpsw on AM335x ICEv2 board, the following needs to be done: 1)There are few on board jumper settings which gives a choice between cpsw and PRUSS, that needs to be properly selected[1]. Even after selecting this, there are few GPIOs which control these muxes that needs to be held high. 2) The clock to PHY is provided by a PLL-based clock synthesizer[2] connected via I2C. This needs to properly programmed and locked for PHY operation. And PHY needs to be reset before before being used, which is also held by a GPIO. 3) RMII mode needs to be selected.

In order to boot to prompt, concole in both u-boot and kernel needs to be changed. qspiboot_defconfig: The only advantage of enabling QSPI_BOOT is selecting env in QSPI.

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.

* ARM: omap-common: Add standard access for board description EEPROMLokesh Vutla2016-03-14-0/+405
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* ARM : DRA7: Switch QSPI to use MODE-0 at 64MHzVignesh R2016-02-15-7/+23
| | | | | | | | | | According to Data Manual(SPRS915P) of AM572x, TI QSPI controller on DRA74 EVM(rev 1.1+) can support up to 64MHz in MODE-0, whereas MODE-3 is limited to 48MHz. Hence, switch to MODE-0 for better throughput. Also, add IODelay parameters for the same. Signed-off-by: Vignesh R <vigneshr@ti.com> Reviewed-by: Tom Rini <trini@konsulko.com>
