fdd243d81b powerpc: mpc8xx: CPM parameter RAM can be anywhere
With relocation, CPM parameter RAM can be anywhere in the
dual port RAM, so don't split dual port RAM.

Remove dparam and dparam16 members of struct comm_proc

PROFF_XXX become offsets from the start of dual port RAM,
then they are now consistant with the offsets in RPBASE
registers.

773ad4ebb1 spi, mpc8xx: Add support for chipselect via GPIO and fixups
This patch fixes the mpc8xx SPI driver:
- A stub callbacks for mode and speed,
- Use chip selects defined as GPIOs,
- Write proper value to disable relocation, other it fails on mpc885,
- Don't modify ports setup, ports can be different from one board to
another and are already set by board_early_init_r().

This patch was originally written by Charles Frey who's
email address is not valid anymore as he left the company.

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.
