Make first step in DT/DM migration. Enable OF_CONTROL only for the main
U-Boot image for now.Remove mmc_init_main() because board_mmc_init() is not called when
DM_MMC is enabled.DM_MMC requires DM_GPIO for card-detect to work. That in turn makes gpio
request mandatory. Add code to request/free gpios in platform code.MMC devices are now numbered according to DT. The SD card is 1, and eMMC
is 2. Account for that in board_mmc_get_env_dev(), BOOT_TARGET_DEVICES,
and has_emmc().DM_MMC requires BLK. However, the (BLK && !DM_USB) combination disables
USB_STORAGE. Enable DM_USB to preserve USB functionality. Add also
DM_REGULATORS for the USB power controller. This allows us to drop
board_ehci_hcd_init() and setup_usb().Runtime selection of DT is necessary because of the i.MX6QD vs i.MX6SDL
incompatibility. DT selection does not rely on GPIOs, since DM_GPIO
depends on DT. Instead, we take one "fully featured" DT of each variant.
That should be enough to boot from both SD card and eMMC.Since we don't select the exact DT, override the generic
show_board_info() that shows the selected DT 'model' field.Signed-off-by: Baruch Siach

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 issueThe 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 unifdeffind drivers/ddr/marvell/a38x/ -name '*.[ch]' | \

The soms with 4GB ddr have a rowaddr of 16 not 15, this allows
the detection mechanism to properly identify them as 4GB.
However these soms can be populated with whatever amount of
memory the customer requests therefor we need a ram stride test.
We can not use the get_ram_size() function because not all 4GB's
of DDR is addressable on a 32-bit architecture. Therefore instead
we use a memory stride of 128MB's and look for the address that
the memory wraps. This function is used for all som types to
catch most memory configurations.This is a revised version of Rabeeh Khoury's original code.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.Signed-off-by: Tom Rini

The order of members in struct hws_topology_map is cas_wl, cas_l. The
comments in the original db-88f6820-gp.c had this wrong and have been
copied to other Armada-385 based boards. Practically this hasn't made a
difference since all these boards set both cas_wl and cas_l to 0
(autodetect) but if there were ever a board that did need to set these
explicitly they would run into unexpected issued.Update the comments to reflect the correct order of structure members.

The DDR3 training code for Marvell A38X currently computes 1t timing
when given board topology map of the Turris Omnia, but Omnia needs 2t.This patch adds support for enforcing the 2t timing in struct
hws_topology_map, through a new enum hws_timing, which can assume
following values:
HWS_TIM_DEFAULT - default behaviour, compute whether to enable 2t
from the number of CSs
HWS_TIM_1T - enforce 1t
HWS_TIM_2T - enforce 2tThis patch also sets all the board topology maps (db-88f6820-amc,
db-88f6820-gp, controlcenterdc and clearfog) to have timing set to
HWS_TIM_DEFAULT.Signed-off-by: Marek Behun
