This erratum only applies to general purpose DDR controllers in LS2.
It shouldn't be applied to DP-DDR controller. Check DDRC versoin number
before applying workaround.

Add built-in memory test to catch errors after DDR is initialized, before
any other transactions. To enable this test, define CONFIG_FSL_DDR_BIST.
An environmental variable "ddr_bist" is checked before starting test.
It takes a while (several seconds) depending on system memory size.

CS0 was not allowed to be empty by u-boot driver in the past to simplify
the driver. This may be inconvenient for some debugging. This patch lifts
the restrictions. Controller interleaving still requires CS0 populated.

Add/update registers for DDR4, including DQ mappings. Allow raw timing
method used for all controllers. Update mode_9 register to 0x500 for
improved stability. Check DDR controller version number individually
in case a SoC has multiple DDR controllers of different versions.
Increase read-write turnaround for DDR4 high speeds.

For fsl-lsch3, IFC is binded with address within 32-bit at fist.
After u-boot relocates to DDR, CS1, CS3 can be binded to higher
address to support large space.

These is a growing trend to license DT files dual GPL and X11
especially in the Linux community. It allows easier reuse of
device trees for other software projects.
This commit prepares for doing so in U-Boot too, since DT files are

Commit d8bafe1310487ba0e0785997726b4792072178d3
"ARMv8: enable DM in vexpress64 board" only enabled DM
for the simulated vexpress64 board (FVP) with the
hardcoded clock value for the simulated board, causing
a console regression on the Juno board which was using
a different clock setting.
Fix this by enabling DM for all vexpress64 boards,
defining the clock frequency per-board, deleting the
static array of PL01x ports from the config file and
relying solely on the port defined in the boardfile
using platform data.

This commit extends the driver model uclass's API by function:
- uclass_get_device_by_name()
And this function returns the device if:
- uclass with given ID, exists,
- device with exactly given name(dev->name), exists,
- device probe, doesn't return an error.
The returned device is activated and ready to use.
Note:
This function returns the first device, which name is equal
to the given one. This means, that using this function you must
assume, that the device name is unique in the given uclass's ID
device list.
