Chris Packham ebb1a59325 ARM: mvebu: a38x: sync ddr training code with mv_ddr-armada-18.09.02
This syncs drivers/ddr/marvell/a38x/ with the mv_ddr-armada-18.09 branch
of https://github.com/MarvellEmbeddedProcessors/mv-ddr-marvell.git.
Specifically this syncs with commit 99d772547314 ("Bump mv_ddr to
release armada-18.09.2").

The complete log of changes is best obtained from the mv-ddr-marvell.git
repository but some relevant highlights are:

  ddr3: add missing txsdll parameter
  ddr3: fix tfaw timimg parameter
  ddr3: fix trrd timimg parameter
  merge ddr3 topology header file with mv_ddr_topology one
  mv_ddr: a38x: fix zero memory size scrubbing issue

The upstream code is incorporated omitting the portions not relevant to
Armada-38x and DDR3. After that a semi-automated step is used to drop
unused features with unifdef

    find drivers/ddr/marvell/a38x/ -name '*.[ch]' | \
        xargs unifdef -m -UMV_DDR -UMV_DDR_ATF -UCONFIG_DDR4 \
                 -UCONFIG_APN806 -UCONFIG_MC_STATIC \
                 -UCONFIG_MC_STATIC_PRINT -UCONFIG_PHY_STATIC \
                 -UCONFIG_64BIT -UCONFIG_A3700 -UA3900 -UA80X0 \
                 -UA70X0

README arm: mvebu: db-88f6820: Add SPL support with DDR init code 2015-07-23 10:39:35 +02:00

Update from original Marvell U-Boot to mainline U-Boot:
-------------------------------------------------------

The resulting image including the SPL binary with the
full DDR setup is "u-boot-spl.kwb".

To update the SPI NOR flash, please use the following
command:

=> sf probe;tftpboot 2000000 db-88f6820-gp/u-boot-spl.kwb;\
sf update 2000000 0 60000

Note that the original Marvell U-Boot seems to have
problems with the "sf update" command. This does not
work reliable. So here this command should be used:

=> sf probe;tftpboot 2000000 db-88f6820-gp/u-boot-spl.kwb;\
sf erase 0 60000;sf write 2000000 0 60000
