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.

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.

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.

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.

We should use unified setup_ddr_tlbs() for spl boot and non-spl boot
to make sure 'M' bit is set for DDR TLB to maintain cache coherence.

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.

Add support of 2 stage NAND/SD boot loader using SPL framework.
PBL initialise the internal SRAM and copy SPL, this further
initialise DDR using SPD and environment and copy u-boot from
NAND/SD to DDR, finally SPL transfer control to u-boot.
NOR uses CS1 instead of CS2 when NAND boot, fix it.

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.

Add emulator support for T4240. Emulator has limited peripherals and
interfaces. Difference between emulator and T4240QDS includes:
ECC for DDR is disabled due the procedure to load images
No board FPGA (QIXIS)
NOR flash has 32-bit port for higher loading speed
IFC and I2C timing don't really matter, so set them fast
No ethernet

Update the timing table to support more rank density, based on the theory
that similar density DIMMs have similar clock adjust and write level start
timing. Update the timing for 1600 and 1866 MT/s. Tested with Micron

The T4240QDS is a high-performance computing evaluation, development and
test platform supporting the T4240 QorIQ Power Architecture™ processor.
SERDES Connections
32 lanes grouped into four 8-lane banks
Two “front side” banks dedicated to Ethernet
Two “back side” banks dedicated to other protocols
DDR Controllers
Three independant 64-bit DDR3 controllers
Supports rates up to 2133 MHz data-rate
Supports two DDR3/DDR3LP UDIMM/RDIMMs per controller
QIXIS System Logic FPGA
Each DDR controller has two DIMM slots. The first slot of each controller
has up to 4 chip selects to support single-, dual- and quad-rank DIMMs.
The second slot has only 2 chip selects to support single- and dual-rank
DIMMs. At any given time, up to total 4 chip selects can be used.
