b9aad37591 fdtdec: Support reserved-memory flags
Reserved memory nodes can have additional flags. Support reading and
writing these flags to ensure that reserved memory nodes can be properly
parsed and emitted.

This converts support for the existing "no-map" flag to avoid extending
the argument list for fdtdec_add_reserved_memory() to excessive length.

ccaa5747bd fdtdec: optionally add property no-map to created reserved memory node
Add boolean input argument @no_map to helper function
fdtdec_add_reserved_memory() to add or not "no-map" property
for an added reserved memory node.

Property no-map is used by the Linux kernel to not not map memory
in its static memory mapping. It is needed for example for the|
consistency of system non-cached memory and to prevent speculative
accesses to some firewalled memory.

No functional change. A later change will update to OPTEE library to
add no-map property to OP-TEE reserved memory nodes.

7fce739665 lib: fdt: Introduce fdtdec_setup_mem_size_base_lowest()
New function should be called from board dram_init() because it initialized
gd->ram_base/ram_size. It finds the lowest available memory.

On systems with multiple memory nodes finding out the first memory node by
fdtdec_setup_mem_size_base() is not enough because this memory can be above
actual U-Boot VA mapping. Currently only mapping till 39bit is supported
(Full 44bit mapping was removed by commit 7985cdf74b ("arm64: Remove
non-full-va map code")).
If DT starts with the first memory node above 39bit address then system can
be unpredictable.

The function is available only when multiple memory bank support is
enabled.

Calling fdtdec_setup_memory_banksize() from dram_init() is not possible
because fdtdec_setup_memory_banksize() is saving dram information to bd
structure which is placed on stack but not initialized at this time. Also
stack is placed at location setup in dram_init().

357d2ceba0 fdtdec: only create phandle if caller wants it in fdtdec_add_reserved_memory()
The phandlep pointer returning the phandle to the caller is optional
and if it is not set when calling fdtdec_add_reserved_memory() it is
highly likely that the caller is not interested in a phandle to the
created reserved-memory area and really just wants that area added.

So just don't create a phandle in that case.

086336a225 fdtdec: protect against another NULL phandlep in fdtdec_add_reserved_memory()
The change adding fdtdec_add_reserved_memory() already protected the added
phandle against the phandlep being NULL - making the phandlep var optional.

But in the early code checking for an already existing carveout this check
was not done and thus the phandle assignment could run into trouble,
so add a check there as well, which makes the function still return
successfully if a matching region is found, even though no-one wants to
work with the phandle.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
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.

3b595da441 fdtdec: allow board to provide fdt for CONFIG_OF_SEPARATE
Similar to CONFIG_OF_BOARD, but in this case the fdt is still built by
u-boot build.  This allows the board to patch the fdt, etc.

In the specific case of dragonboard 410c, we pass the u-boot generated
fdt to the previous stage of bootloader (by embedding it in the
u-boot.img that is loaded by lk/aboot), which patches the fdt and passes
it back to u-boot.
