imx: reorganize IMX code as other SOCs

2017-07-12T08:17:44+00:00

Change is consistent with other SOCs and it is in preparation
for adding SOMs. SOC's related files are moved from cpu/ to
mach-imx/.

This change is also coherent with the structure in kernel.

mx7ulp: Add HAB boot support

2017-03-17T08:27:08+00:00

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.

imx: mx7ulp: Add clock framework and functions

2017-03-17T08:27:08+00:00

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.
