This patch add support for gpimage format as a preparatory patch for porting u-boot for keystone2 devices and is based on omapimage format. It re-uses gph header to store the size and loadaddr as done in omapimage.c

This patch moves the davinci i2c_defs.h file to drivers.i2c directory. It will allow to reuse the davinci_i2c driver for TI Keystone2 SOCs.

Not used "git mv" command to move the file because small part of it with definitions specific for Davinci SOCs has to remain in the arch/arm/include/asm/arch-davinci.

From: Vitaly Andrianov vitalya@ti.com

k2hk EVM is based on Texas Instruments Keystone2 Hawking/Kepler SoC. Keystone2 SoC has ARM v7 Cortex-A15 MPCore processor. Please refer the ti/k2hk_evm/README for details on the board, build and other information.

This patch add support for keystone architecture and k2hk evm.

Multicore navigator consists of Network Coprocessor (NetCP) and Queue Manager sub system. More details on the hardware can be obtained from the following links:-

Network Coprocessor: http://www.ti.com/lit/pdf/sprugz6 Multicore Navigator: http://www.ti.com/lit/pdf/sprugr9

Multicore navigator driver implements APIs to configure the Queue Manager and NetCP Pkt DMA.

Ethernet driver configures the CPSW, SGMI and Phy and uses the the Navigator APIs. The driver supports 4 Ethernet ports and can work with only one port at a time.

Port configurations are defined in board.c.

Currently davinci spi driver supports only bus 0 cs 0. This patch allows driver to support bus 1 and bus 2 with configurable number of chip selects. Also defaults are selected in a way to avoid regression on other platforms that uses davinci spi driver and has only one spi bus.

currently only spi0 is enabled on k2hk evm. This configuration update is needed to enable spi1 and spi2.
