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>

Current codes assume the OPTEE address is at the end of first DRAM bank.
Adjust the process to allow OPTEE in the middle of first bank.
When OPTEE memory is removed from first bank, it may split the first bank
to two banks, adjust the MMU table for the split case,
Since the default CONFIG_NR_DRAM_BANKS is 4, it is enough, just enlarge
i.MX8MP evk to default to avoid issue.

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.

It is bad practice to include common.h in other header files since it can
bring in any number of superfluous definitions. It implies that some C
files don't include it and thus may be missing CONFIG options that are set
up by that file. The C files should include these themselves.
Update some header files in arch/arm to drop this.

At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in
U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
which needs to use the system malloc() in some files.
Move the compatibility features into a separate header file.

This patch enable convert DM MMC for imx7d-pico board and variant.
Before the DM conversion only usdhc3 was enabled and therefore it appeared
as MMC 0 to u-boot. After enabling MMC DM though usdhc3 defaults to MMC 2,
which left unattended would drive changes to existing pico-pi bootscripts and
environment variables that rely on mmc 0.
Setup the alias of mmc0 and usdhc3 so that existing pico-imx7d boot code will
work unmodified.
When converting to DM_MMC it is necessary that SPL initializes eMMC
by itself, so move the original eMMC initialization from U-Boot
proper to SPL.

Since commit 9e3c0174da842 ("pico-imx7d: Add LCD support") we started to
notice some hangs in U-Boot.
There is not an issue on such commit per se, but due to the LCD support
the current drawn is increased and this may cause issues when powering
pico-imx7d-pi from USB.
Some computers may be a bit strict with USB current draw and will
shut down their ports if the draw is too high.
The solution for that is to use an externally powered USB hub between the
board and the host computer.
Add such recommendation to the README file.

After the DM_MMC conversion the following eMMC boot error is observed:
U-Boot SPL 2019.04-rc4 (Mar 20 2019 - 18:53:28 +0000)
Trying to boot from MMC1
MMC Device 0 not found
spl: could not find mmc device 0. error: -19
SPL: failed to boot from all boot devices
### ERROR ### Please RESET the board ###
This happens because the SPL code does not initialize the SDHC pins
and clock.
Fix it by moving the original eMMC initialization from U-Boot proper
to SPL.
