This was imported from Linux 4.9 and adjusted for U-Boot.

 - Replace the license block with SPDX
 - Drop all *_atomic variants, which make no sense for U-Boot
 - Remove the sleep_us argument, which makes no sense for U-Boot

Currently, mdelay() and udelay() are declared in include/common.h,
while ndelay() in include/linux/compat.h.  It would be nice to
collect them into include/linux/delay.h like Linux.

While we are here, fix the ndelay() implementation; I used the
DIV_ROUND_UP() instead of (x)/1000 because it must wait *longer*
than the given period of time.

Both AM57xx and DRA7xx share the same set of base addresses for DWC
controllers. The usage however differ with DWC2 instance used typically
in AM57xx evms while DWC1 instances used in DRA7x platforms.

Use TARGET_SOC config to differentiate so that CONFIG_AM57XX can be dropped.

Eventually, this needs to be dt-fied.

Commit c68c62 ("i2c: mvtwsi: Make delay times frequency-dependent")
extensively used the ndelay function with a calculated parameter
which is dependant on the configured frequency of the I2C bus. If
standard speed is employed, the parameter is usually 10000 (10000ns
period length for 100kHz frequency).

But, since the arm architecture does not implement a proper version of
ndelay, the fallback default from include/linux/compat.h is used,
which defines every ndelay as udelay(1). This causes problems for
slower speeds on arm, since the delay time is now 9us too short for
the desired frequency, which leads to random failures of the I2C
interface.

To remedy this, we implement a proper, parameter-aware ndelay fallback
for architectures that don't implement a real ndelay function.

INFO macro make flash table entries more adjustable like
adding new flash_info attributes, update ID length bytes
and so on and more over it will sync to Linux way of defining
flash_info attributes.

- Add JEDEC_ID
- Add JEDEC_EXT macro
- Add JEDEC_MFR
- spi_flash_params => spi_flash_info
- params => info

We have list_first_entry() but in some cases it is useful to find the last

Currently the controller by default enables the Receive Detect feature in P3
mode in USB 3.0 PHY. However, USB 3.0 PHY does not reliably support receive
detection in P3 mode.
Enabling the USB3 controller to configure USB in P2 mode whenever the Receive
Detect feature is required.
