f1683aa73c board_f: Rename initdram() to dram_init()
This allows us to use the same DRAM init function on all archs. Add a
dummy function for arc, which does not use DRAM init here.

088454cde2 board_f: Drop return value from initdram()
At present we cannot use this function as an init sequence call without a
wrapper, since it returns the RAM size. Adjust it to set the RAM size in
global_data instead, and return 0 on success.

52c411805c board_f: Drop board_type parameter from initdram()
It looks like only cm5200 and tqm8xx use this feature, so we don't really
need it in generic code. Drop it and have the users access gd->board_type
directly.

5b8031ccb4 Add more SPDX-License-Identifier tags
In a number of places we had wordings of the GPL (or LGPL in a few
cases) license text that were split in such a way that it wasn't caught
previously.  Convert all of these to the correct SPDX-License-Identifier
tag.

5614e71b49 Driver/DDR: Moving Freescale DDR driver to a common driver
Freescale DDR driver has been used for mpc83xx, mpc85xx, mpc86xx SoCs.
The similar DDR controllers will be used for ARM-based SoCs.

0dd38a35f4 powerpc: Fix CamelCase warnings in DDR related code
Some DDR related structures present in fsl_ddr_dimm_params.h, fsl_ddr_sdram.h, ddr_spd.h
has various parameters with embedded acronyms capitalized that trigger the CamelCase
warning in checkpatch.pl

Convert those variable names to smallcase naming convention and modify all files
which are using these structures with modified structures.

712cf7ab0b powerpc/mpc8xxx: Merge entries in DDR speed table
It is not necessary to keep multiple entries for the same setting in DDR
speed tables. Merge them for smaller tables. Also restructure the tables
for smaller size. Cleanup some typedefs.

Enforce strict checking for speed table. If DIMM is running at higher than
known speed, try to use the highest speed setting. If rank is unknown, it
has to panic.

Removed ODT overriding for P2020DS as it is not necessary.

This table covers DDR frequencies from 666 to 1666. Frequencies 666, 833,
1000, 1066 and 1333 were verified on this board with SO-DIMM
(UG51U6400N8SU-ACF).

21cd5815a7 MPC8xxx: drop redundant boot messages
Current code would print RAM size information like this:

	DRAM:  DDR: 256 MiB (DDR1, 64-bit, CL=2, ECC off)

Turn a number of printf()s into debug() to get rid of the redundant
"DDR: " string like this:

	DRAM:  256 MiB (DDR1, 64-bit, CL=2, ECC off)
