In order to finish moving this symbol to Kconfig for all platforms, we
need to do a few more things. First, for all platforms that define this
to a function, introduce CONFIG_DYNAMIC_SYS_CLK_FREQ, similar to
CONFIG_DYNAMIC_DDR_CLK_FREQ and populate clock_legacy.h. This entails
also switching all users from CONFIG_SYS_CLK_FREQ to get_board_sys_clk()
and updating a few preprocessor tests.
With that done, all platforms that define a value here can be converted
to Kconfig, and a fall-back of zero is sufficiently safe to use (and
what is used today in cases where code may or may not have this
available). Make sure that code which calls this function includes
<clock_legacy.h> to get the prototype.

There is no "fsl,ls1028a-gpu" compatible string. It is solely for the
proprietary driver which will never be open source. Lately, linux gained
support for the open source etnaviv driver for the GPU (although there
is still support for the DisplayPort PHY missing to get actual graphics
output). Thus, instead of supporting some proprietary driver, switch
over to the open source one, which also have an official device tree
binding.

The Linux coding style guide (Documentation/process/coding-style.rst)
clearly says:
It's a **mistake** to use typedef for structures and pointers.
Besides, using typedef for structures is annoying when you try to make
headers self-contained.
Let's say you have the following function declaration in a header:
void foo(bd_t *bd);
This is not self-contained since bd_t is not defined.
To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h>
#include <asm/u-boot.h>
void foo(bd_t *bd);
Then, the include direcective pulls in more bloat needlessly.
If you use 'struct bd_info' instead, it is enough to put a forward
declaration as follows:
struct bd_info;
void foo(struct bd_info *bd);
Right, typedef'ing bd_t is a mistake.
I used coccinelle to generate this commit.
The semantic patch that makes this change is as follows:

typedef bd_t;

Virtually all callers of this function do the rounding on their own.
Some do it right, some don't. Instead of doing this in each caller,
do the rounding in efi_add_memory_map(). Change the size parameter
to bytes instead of pages and remove aligning and size calculation in
all callers.
There is no more need to make the original efi_add_memory_map() (which
takes pages as size) available outside the module. Thus rename it to
efi_add_memory_map_pg() and make it static to prevent further misuse
outside the module.

JR3 was getting removed from device tree only if random number

JR3 should be removed from device tree node irrespective of the
random seed generation as SEC firmware reserves it for it's use.
Not removing it in case of random number generation failure causes
the kernel to crash.
Random number generation was being called twice. This is not
required. If SEC firmware is running, SIP call can be made to the SEC
firmware to get the random number. This call itself would return
failure if function is not supported. Duplicate calling of random
number generation function has been removed.

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
