51370d5618 ddr: fsl: Merge macro CONFIG_NUM_DDR_CONTROLLERS and CONFIG_SYS_NUM_DDR_CTRLS
These two macros are used for the same thing, the total number of DDR
controllers for a given SoC. Use SYS_NUM_DDR_CTRLS in Kconfig and
merge existing usage.

02fb276157 fsl/ddr: Add erratum_a009942_check_cpo and clean related erratum
- add additional function erratum_a009942_check_cpo to check if the
  board needs tuning CPO calibration for optimal setting.
- move ERRATUM_A009942(with revision to check cpo_sample option) from
  fsl_ddr_gen4.c to ctrl_regs.c for reuse on all DDR4/DDR3 parts.
- move ERRATUM_A008378 from fsl_ddr_gen4.c to ctrl_regs.c
- remove obsolete ERRATUM_A004934 which is replaced with ERRATUM_A009942.

5b8031ccb4 Add more SPDX-License-Identifier tags
In a number of places we had wordings of the GPL (or LGPL in a few
cases) license text that were split in such a way that it wasn't caught
previously.  Convert all of these to the correct SPDX-License-Identifier

03e664d8f4 driver/ddr/fsl: Add support for multiple DDR clocks
Controller number is passed for function calls to support individual
DDR clock, depending on SoC implementation. It is backward compatible
with exising platforms. Multiple clocks have been verifyed on LS2085A
emulator.

a7787b7850 fsl/sleep: updated the deep sleep framework for QorIQ platforms
With the introducing of generic board and ARM-based cores, current
deep sleep framework doesn't work anymore.
This patch will convert the current framework to adapt this change.
Basically it does:
1. Converts all the Freescale's DDR driver to support deep sleep.
2. Added basic framework support for ARM-based and PPC-based
cores separately.

aade20046b mpc85xx/t104x: Add deep sleep framework support
When T104x soc wakes up from deep sleep, control is passed to the
primary core that starts executing uboot. After re-initialized some
IP blocks, like DDRC, kernel will take responsibility to continue
to restore environment it leaves before.

76356eb57c powerpc/mpc85xx: Revise workaround for DDR-A003
Existing workaround only handles one RDIMM on reference design. In case
of two RDIMMs being used, the workaround requires two separate writes to
DDR_SDRAM_MD_CNTL register.

This patch also restores two debug registers changed by the workaround.

5614e71b49 Driver/DDR: Moving Freescale DDR driver to a common driver
Freescale DDR driver has been used for mpc83xx, mpc85xx, mpc86xx SoCs.
The similar DDR controllers will be used for ARM-based SoCs.
