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
</smpl>

We should not use typedefs in U-Boot. They cannot be used as forward
declarations which means that header files must include the full header to
access them.
Drop the typedef and rename the struct to remove the _s suffix which is
now not useful.
This requires quite a few header-file additions.

Move this header out of the common header. Network support is used in
quite a few places but it still does not warrant blanket inclusion.
Note that this net.h header itself has quite a lot in it. It could be
split into the driver-mode support, functions, structures, checksumming,
etc.

This syncs drivers/ddr/marvell/a38x/ with the mv_ddr-armada-18.09 branch
of https://github.com/MarvellEmbeddedProcessors/mv-ddr-marvell.git.
Specifically this syncs with commit 99d772547314 ("Bump mv_ddr to
release armada-18.09.2").
The complete log of changes is best obtained from the mv-ddr-marvell.git
repository but some relevant highlights are:
ddr3: add missing txsdll parameter
ddr3: fix tfaw timimg parameter
ddr3: fix trrd timimg parameter
merge ddr3 topology header file with mv_ddr_topology one
mv_ddr: a38x: fix zero memory size scrubbing issue
The upstream code is incorporated omitting the portions not relevant to
Armada-38x and DDR3. After that a semi-automated step is used to drop
unused features with unifdef
find drivers/ddr/marvell/a38x/ -name '*.[ch]' | \
xargs unifdef -m -UMV_DDR -UMV_DDR_ATF -UCONFIG_DDR4 \

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.

The order of members in struct hws_topology_map is cas_wl, cas_l. The
comments in the original db-88f6820-gp.c had this wrong and have been
copied to other Armada-385 based boards. Practically this hasn't made a
difference since all these boards set both cas_wl and cas_l to 0
(autodetect) but if there were ever a board that did need to set these
explicitly they would run into unexpected issued.
Update the comments to reflect the correct order of structure members.

The DDR3 training code for Marvell A38X currently computes 1t timing
when given board topology map of the Turris Omnia, but Omnia needs 2t.
This patch adds support for enforcing the 2t timing in struct
hws_topology_map, through a new enum hws_timing, which can assume
following values:
HWS_TIM_DEFAULT - default behaviour, compute whether to enable 2t
from the number of CSs
HWS_TIM_1T - enforce 1t
HWS_TIM_2T - enforce 2t
This patch also sets all the board topology maps (db-88f6820-amc,
db-88f6820-gp, controlcenterdc and clearfog) to have timing set to
HWS_TIM_DEFAULT.
