2018ef868c imx: mx7ulp: Fix SPLL/APLL clock rate calculation issue
The num/denom is a float value, but in the calculation it is convert
to integer 0, and wrong result.

27117b2024 mx7ulp: Add HAB boot support
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.

1b409828b1 imx: mx7ulp: Add soc level initialization codes and functions
Implement soc level functions to get cpu rev, reset cause, enable cache,
etc. We will disable the wdog and init clocks in s_init at very early u-boot
phase.

Since the we are seeking the way to get chip id for mx7ulp, the get_cpu_rev
is hard coded to a fixed value. This may change in future.

Reuse some code in imx-common.

d0f8516d9e imx: mx7ulp: Add clock framework and functions
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.

0cb3d82c68 imx: mx7ulp: add iomux driver to support IOMUXC0 and IOMUXC1
Add a new driver under ULP directory to support its IOMUXC
controllers. The ULP has two IOMUXC, the IOMUXC0 is used
for M4 domain, while IOMUXC1 is for A7. We set IOMUXC1 as
the default IOMUX in this driver. Any pins in IOMUXC0 needs
to configure with IOMUX_CONFIG_MPORTS in its mux_mode field.
