USB-C power supply which are Power Delivery compliant (USB-PD) are able
to provide different voltage/current (for example 5V/3A 9V/3A 12V/2.25A...)
In this case, the power supply need to negotiate the voltage/current to
use with the device using CC1/CC2 USB-C signals.
If this negotiation occurs during ADC measurement (done also on CC1/CC2
USB-C signals) some ADC acquisition can be corrupted which cause wrong
power supply current detection.
To avoid this, the power supply current detection algorithm is updated
as following:
- perform an ADC measurement, if a 3A current is detected, continue the
boot process.
- else, wait 20ms (max tPDDebounce duration) to ensure that USB-PD
negotiation is done and perform another ADC measurement.

In the spirit of using the same base name for all of these related macros,
rename this to have the operation at the end. This is not widely used so
the impact is fairly small.
Signed-off-by: Simon Glass <sjg@chromium.org>
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.

Update kernel load address for FIT examples to avoid relocation:
- Kernel example uses Image.gz with U-Boot gzip decompression
at final kernel location 0x0xC0008000.
- Copro example loads zImage at a correct location (0xC4000000),
to avoid zImage relocation before decompression by kernel code.
An other solution to avoid zImage relocation is to align
the kernel load and entry address with the real location in FIT
(the relocation of zImage is skipped in U-Boot bootm command for
identical address) but it is less flexible because this offset
depends on FIT content:
For example:
## Loading kernel from FIT Image at c2000000 ...
Using 'ev1' configuration
Trying 'kernel' kernel subimage
Description: Linux kernel
Created: 2020-10-22 9:08:32 UTC

The kernel offset in FIT is 0xCC in FIT and zImage is decompressed at
0xC0008000 by kernel code:

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;
