2017-03-17mx7ulp: Add HAB boot supportPeng Fan
Add CAAM clock functions, SEC_CONFIG[1] fuse checking, and default CSF size for HAB support boot on mx7ulp. Users need to uncomment the CONFIG_SECURE_BOOT in mx7ulp_evk.h to build secure uboot.

2017-03-17imx: mx7ulp: Implement the clock functions for i2c driverYe Li
Implement the i2c clock enable and get function for mx7ulp. These functions are required by imx_lpi2c driver. Signed-off-by: Peng Fan <peng.fan@nxp.com> Signed-off-by: Ye Li <ye.li@nxp.com> Reviewed-by: Stefano Babic <sbabic@denx.de>
2017-03-17imx: mx7ulp: Add clock framework and functionsPeng Fan
Add a clock framework to support SCG1/PCC2/PCC3 for A7 to support get/set clock source, divider, clock rate and parent source. Users need to include pcc.h to use the APIs to for peripherals clock. Each peripheral clock is defined in enum pcc_clk type. SCG relevants APIs are defined in scg.h which supports clock rate get, PLL/PFD enablement and settings, and all SCG clock initialization. User need use enum scg_clk to access each clock source. In clock.c, we initialize necessary clocks at u-boot s_init and implement the clock functions used by driver modules to operate clocks dynamically.
