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.

Added support for K2G EVM with FlipChip SoC of which
ARM/DDR3 runs at 1GHz/1066 MT/s. The patch is also
backward compatible with old revision EVM and EVM
with WireBond SoC. Their ARM/DDR3 run at 600MHz/800 MT/s.
The new SoC supports 2 different speeds at 1GHz and 600MHz.
Modyfied the CPU Name to show which SoC is used in the EVM.
Modified the DDR3 configuration to reflect New SoC supports
2 different CPU and DDR3 speeds, 1GHz/1066MT and 600MHz/800MT.

On early K2 devices (eg. K2HK) the secure ROM code does not support
loading secure code to firewall protected memory, before decrypting,
authenticating and executing it.
To load the boot monitor on these devices, it is necessary to first
authenticate and run a copy loop from non-secure memory that copies
the boot monitor behind firewall protected memory, before decrypting
and executing it.
On K2G, the secure ROM does not allow secure code executing from
unprotected memory. Further, ROM first copies the signed and encrypted
image into firewall protected memory, then decrypts, authenticates
and executes it.
As a result of this, we cannot use the copy loop for K2G. The
mon_install has to be modified to pass the address the signed and
encrypted secure boot monitor image to the authentication API.
For backward compatibility with other K2 devices and K2G GP,
the mon_install API still supports a single argument. In this case
the second argument is set to 0 by u-boot and is ignored by ROM

Following are the 3 events that can controlled bt the reset mux:
- Device Reset
- An interrupt to the ARM_GIC
- An interrupt to the ARM_GIC followed by a device reset.

NOTE: Few of these might have default configurations, however,
since most are software configurable, it is better to explicitly
configure the system to have a known default state.
Without programming these, we end up seeing lack of coherency on certain
peripherals resulting in inexplicable failures (such as USB peripheral's
DMA data not appearing on ARM etc and weird workarounds being done by
drivers including cache flushes which tend to have system wide
performance impact).
By marking these segments as shared, we also ensure SoC wide coherency
is enabled.

MSMC segment Privilege ID is not consistent accross the keystone2 SoCs.
As the first step to ensure complete SoC wide coherency setup, lets
refactor the macros to remove the #if-deffery around the code which
obfuscates which IDs are actually enabled for which SoC.
As a result of this change the PCIe configuration is moved after the
msmc configuration is complete, but that should ideally have no
functional impact.

Because KS2 u-boot works in 32 bit address space the existing ram_size
global data field cannot be used. The maximum, which the get_ram_size()
can detect is 2GB only. The ft_board_setup() needs the actual ddr3 size
to fix up dtb.
This commit introduces the ddr3_get_size() which uses SPD data to
calculate the ddr3 size. This function replaces the "ddr3_size"
environment variable, which was used to get the SODIMM size.
For platforms, which don't have SODIMM with SPD and ddr3 is populated to
a board a simple ddr3_get_size function that returns ddr3 size has to be
implemented. See hardware-k2l.h
