Originally, u-boot SPL will place the DTB directly after the kernel,
but the size of the kernel does not include the BSS section, This
means that u-boot SPL places the DTB in the kernel BSS section causing
the DTB to be cleared by the kernel BSS initialisation.
Moving the DTB in front of the kernel can avoid this error.

Original OpenSBI (without FW_PIC) will relocate itself
from 0x1000000 to 0x0. After OpenSBI added FW_PIC codes,
it will not relocate any more and always run at 0x1000000.
Hence, it may overlap with Kernel memory region. So it is
necessary to change OpenSBI address from 0x1000000 to 0x0.

OF_HOSTFILE is used on sandbox configs only. Although it's pretty
unique and not causing any confusions, we are better of having simpler
config options for the DTB.
So let's replace that with the existing OF_BOARD. U-Boot would then
have only three config options for the DTB origin.
- OF_SEPARATE, build separately from U-Boot
- OF_BOARD, board specific way of providing the DTB
- OF_EMBED embedded in the u-boot binary(should not be used in production

At some point back in 2018 prior_stage_fdt_address and OF_PRIOR_STAGE got
introduced, in order to support a DTB handed over by an earlier stage boo
loader. However we have another option in the Kconfig (OF_BOARD) which has
identical semantics.
On RISC-V some of the boards pick up the DTB from a1 and copy it in their
private gd_t. Apart from that they copy it to prior_stage_fdt_address, if
the Kconfig option is selected, which is unnecessary.
So let's switch the config option for those boards to OF_BOARD and define
the required board_fdt_blob_setup() for them.

Move this out of the common header and include it only where needed. In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly. Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so

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:
<smpl>
@@
typedef bd_t;
@@
-bd_t
+struct bd_info

ax25-ae350 use CONFIG_OF_BOARD via a2 and CONFIG_SYS_SDRAM_BASE

But after this patch
riscv: save hart ID and device tree passed by prior boot stage
It provide prior_stage_fdt_address which offer a temporary
memory address to keep the dtb address passing from loader(gdb)
to u-boot with a1.
So passing via a2 and CONFIG_SYS_SDRAM_BASE is redundant and
can be removed. And it also somehow may corrupted BBL if it
was be arranged in CONFIG_SYS_SDRAM_BASE.
In board_fdt_blob_setup()
When boting from ram:
prior_stage_fdt_address will be use to reserved dtb temporarily.
When booting from ROM:
dtb will be pre-burned in CONFIG_SYS_FDT_BASE, if it is flash base.
Or CONFIG_SYS_FDT_BASE maybe a memory map space (NOT RAM or ROM)
which is provided by HW.

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.

Enable CONFIG_OF_BOAD to support delivery dtb to u-boot
at run time instead of embedded.
There are two methods to delivery dtb.
1 Pass from loader:
When u-boot boot from RAM, gdb or loader can pass dtb
via a2 to u-boot dynamically. Of course gdb or loader
shall be in charge of dtb delivery.
2 Configure CONFIG_SYS_FDT_BASE:
It can be configured as RAM or ROM base statically,
no mater u-boot boot from RAM or ROM.
If it was configured as ROM base, dtb can be burned
into ROM(spi flash) by spi driver.
Meanwhile remove CONFIG_SKIP_LOWLEVEL_INIT which is
useless in nx25-ae250 configuration.
