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 Signed-off-by: Chris Packham <judge.packham@gmail.com> Reviewed-by: Stefan Roese <sr@denx.de> Tested-by: Baruch Siach <baruch@tkos.co.il> Signed-off-by: Stefan Roese <sr@denx.de>
Update from original Marvell U-Boot to mainline U-Boot:
-------------------------------------------------------
Generate the U-Boot image with these commands:
$ make clearfog_defconfig
$ make
The resulting image including the SPL binary with the
full DDR setup is "u-boot-spl.kwb".
Now all you need to do is copy this image on a SD card.
For example with this command:
$ sudo dd if=u-boot-spl.kwb of=/dev/sdX bs=512 seek=1
Please use the correct device node for your setup instead
of "/dev/sdX" here!
Boot selection:
---------------
Before powering up the board, boot selection should be done via the SW1 dip
switch (0: OFF, 1: ON):
- SPI: 00010
- SD/eMMC: 00111
- M.2 SSD: 11100
- UART: 01001 [1]
[1]: According to SolidRun's manual, 11110 should be used for UART booting on
the ClearFog 'Pro' variant.
However, this doesn't work (anymore) at least on Rev. 2.1 (but '01001' as
mentionend for the 'Base' variant does).
Boot from UART:
---------------
Connect the on-board micro-USB (CF Pro: CON11, CF Base: CON5)
to your host.
Set the SW1 DIP switches to UART boot (see above).
Run the following command to initiate U-Boot download:
./tools/kwboot -b u-boot-spl.kwb /dev/ttyUSBX
Use the correct UART device node for /dev/ttyUSBX.
When download finishes start your favorite terminal emulator
on /dev/ttyUSBX.
