83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

71775d3b54 powerpc/mpc85xx: Set SYSCLK to the required frequency
For ICS307-02, there is one general expression to generate SYSCLK:
CLK1Frequency = InputFrequency * 2 * (VDW + 8) / ((RDW + 2) * OD)

If we want the required frequency for SYSCLK, we must find one solution
to generate this frequency, this solution includes VDW, RDW and OD.
For OD, there are only eight option value: 10, 2, 8, 4, 5, 7, 3, 6.
For RDW, the range is 1 to 127.
For VDW, the range is 4 to 511.

First, we use one OD, RDW and required SYSCLK to calculate the VDW,
if VDW is in it's range, we will calculate the CLK1Frequency with
the OD, RDW and VDW calculated, and we will check this percent
(CLK1Frequency / required SYSCLK), and the precision is 1/1000.
if the percent is less than 1/1000, we think the CLK1Frequency is we want.
Otherwise, We will continue to calculate it with the next OD and RDW.

ebf9d5261e Move ICS CLK chip frequency calculation code into a common board library
We have several boards that use the same ICS307 CLK chip to drive the
System clock and DDR clock.  Move the code into a common location so we
share it.

Convert the P2020DS board as the first to use the new common ICS307
code.
