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.

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

The internal SRAM of Freescale's IFC NAND machine is of 64K and controller's
Address Mask Registers is initialised with the same.
So Update TLB and LAW size of NAND flash accordingly.

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.
Detail information can be found in doc/README.t4qds
