Currently the fdtfile environment variable is set to
CONFIG_DEFAULT_DEVICE_TREE which is іnternally used as U-Boot devicetree
source. The OS can use a different filename and Kconfig gives us the
ability to select a default devicetree via CONFIG_DEFAULT_FDT_FILE.
This also gives user configuring U-Boot via menuconfig the behaviour
someone would expect.

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.

Migrate the option CONFIG_SPL_FRAMEWORK and make this gate most of the
current set of options we have in Kconfig. We will need to have some
options available for SPL and !SPL_FRAMEWORK so this is important. In a
few cases we re-order existing options so that we have less escapes from
the SPL_FRAMEWORK guard.

On the NIOS2 and Xtensa architectures, we do not have
CONFIG_SYS_TEXT_BASE set. This is a strict migration of the current
values into the defconfig and removing them from the headers.
I did not attempt to add more default values in and for now will leave
that to maintainers.

rockchip-common.h already defines values that are missing from
rk3368_common.h
For example BOOT_TARGET_DEVICES was defined empty and therefore
distroboot had no boot targets.

We can finally drop TPL_STACK, TPL_TEXT_BASE and TPL_MAX_SIZE off the
whitelist (this time it's really happening!) and migrate the setting
(only used on the RK3368-uQ7 so far) into Kconfig.

To build TPL and SPL stages for the RK3368, we will also need to

For the RK3368, we use a multi-stage boot-process consisting of the
following:
1. TPL: initalises DRAM, returns to boot-ROM (which then loads
the next stage and transfers control to it)
2. SPL: a full-features SPL stage including OF_CONTROL and FIT
image loading, which fetches the ATF, DTB and full U-Boot
and then transfers control to the ATF (using the BL31
parameter block to indicate the location of BL33/U-Boot)
3. ATF: sets up the secure world and exits to BL33 (i.e. a full
U-Boot) in the normal world
4. full U-Boot
TPL/SPL and the full U-Boot are built from this tree and need to
run from distinct text addresses and with distinct initial stack
pointer addresses.
This commit sets up the configuration to run:
- TPL from the SRAM at 0xff8c0000 (note that the first 0x1000
are reserved for use by the boot-ROM and contain the SP
when the TPL is entered)
- SPL from DRAM at 0x0
- U-Boot from DRAM at 0x200000

The BootROM of the RK3368 Boot ROM does not initialise cntfrq_el0.
This change defines COUNTER_FREQUENCY, which is used by the AArch64 init
code in arch/arm/cpu/armv8/start.S to set up cntfrq_el0.
If the counter-frequency is not correctly set up, the calculation of
delays using the ARMv8 generic timer can not work correctly.
