Since LCDIF does not have a dedicated PLL as its source, we have to
find a best frequency closed to the target frequency. The previous
method is finding a closed clock with actual frequency higher than target.
But this causes problem to DSI PHY clock which uses target frequency to
calculate its clock parameters. When the actaul pixclock is higher,
it may violates the requirement between DSI PHY clock and LCDIF pixclock clock.
clk_byte_freq >= dpi_pclk_freq * DPI_pixel_size / ( 8 * (cfg_num_lanes + 1))
So we'd better selecting a LCDIF clock not exceed the target frequency.

The iMX7D has 10 tamper pins those can be used for SNVS tamper detection.
Tamper 9 pin is NVCC_DRAM power switch for LPSR by default.
It must be fused to tamper function by command

FIT image by new UUU command SDPV.
When using the SDPV, the uuu will continue to send out data after first

of the second boot loader, and the padding data before second boot loader
will be sent out. So we have to search the FIT header or container header

When doing partition reboot, the boot image won't be reloaded by ROM,
it is just CPU reset to boot entry. The SW has to keep the boot image
inside the RAM unchanged. It includes both the TEXT section and DATA
section.
For SPL, the problem is DATA section will be updated at runtime, so in
next partition reboot the data is not same as the initial value from
cold boot. If any code depends on the initial value, then it will have
problem.
This patch introduces a mechanism to recover the data section for partition
reboot. It adds a new section in image for saving data section. When from cold
boot, the data section will be saved to that new section at SPL early phase.
When from partition reboot, the data section will be restored from the new section.
