Now that it is possible to use regulator-fixed-clock make use
of it. This makes U-Boot detect the PHY on first cold-boot.
This commit also adjusts the code in setup_fec and follows
how it is done in mx6ullevk.c
This commit also slows down the boot-process by about 150ms
as it now waits for the regulator-fixed-clock voltage that
drives the PHY to go up.
If you rely on very fast boot-speeds and don't need ethernet
for your boot-process you can safely revert the changes on
imx6ull-colibri.dtsi

Toradex uses the variable variant to distinguish between modules with
eMMC, NAND with wifi and NAND without wifi.
This variable is set on every boot. Set this variable also if we have a
NAND module without wifi to prevent issues.

'Colibri iMX6ULL 1GB' which has a eMMC instead of the raw NAND used
on other SKUs.

NXP used to setup the gpmi clock root from gpmi_clk in early versions
in their downstream BSP. [1]
However on mainline the gpmi clock root was always setup from enfc
since the beginning of the i.MX 6 series SoCs, which is still the same
today. [2]
NXP followed the mainline approach at some point and changed
setup_gpmi_io_clk to setup gpmi clock root from enfc which left faulty
code behind in our board file. [3]
This commit follows the change of NXP as it improves the performance of
the NAND from ~1.2 MiB/s to ~12 MiB/s. [3]
This change was verified to work in recovery-mode and u-boot loaded
from NAND on all four Colibri iMX6ULL SKUs from Toradex.
The frequency used to read the NAND, measured on RE# (Read Enable):
before this patch: 1.4 MHz
after this patch: 22 MHz
in Linux Kernel: 50 MHz

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
remove that include.

The current macro is a misnomer since it does not declare a device
directly. Instead, it declares driver_info record which U-Boot uses at
runtime to create a device.
The distinction seems somewhat minor most of the time, but is becomes
quite confusing when we actually want to declare a device, with
of-platdata. We are left trying to distinguish between a device which
isn't actually device, and a device that is (perhaps an 'instance'?)
It seems better to rename this macro to describe what it actually is. The
macros is not widely used, since boards should use devicetree to declare
devices.
Rename it to U_BOOT_DRVINFO(), which indicates clearly that this is
declaring a new driver_info record, not a device.

We use 'priv' for private data but often use 'platdata' for platform data.
We can't really use 'pdata' since that is ambiguous (it could mean private
or platform data).
Rename some of the latter variables to end with 'plat' for consistency.

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
