mx6cuboxi: fix 4GB ddr memory detection

2018-06-18T14:50:55+00:00

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.

mx6cuboxi: consolidate board detection and add som revision checking

2018-06-18T14:50:40+00:00

In order to properly detect the board the checks need to be done
in a specific order.  Move these tests back into a single enum
function that will always return the proper the board it is checking.

This also adds the best test we have for detecting the rev 1.5 som,
and it simplifies the device-tree filename building.

arm: mvebu: switch clearfog to use device-tree i2c and gpio

2018-06-05T05:29:09+00:00

This switches the clearfog boards to use DM based gpio and i2c
drivers.  The io expanders are configured via their device-tree
entries.

ARM: mvebu: a38x: restore support for setting timing

2018-05-14T08:01:56+00:00

This restores support for configuring the timing mode based on the
ddr_topology. This was originally implemented in commit 90bcc3d38d2b
("driver/ddr: Add support for setting timing in hws_topology_map") but
was removed as part of the upstream sync.

ARM: mvebu: a38x: sync ddr training code with upstream

2018-05-14T08:01:56+00:00

This syncs drivers/ddr/marvell/a38x/ with the mv_ddr-armada-17.10 branch
of https://github.com/MarvellEmbeddedProcessors/mv-ddr-marvell.git.

The upstream code is incorporated omitting the ddr4 and apn806 and
folding the nested a38x directory up one level. 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

INTER_REGS_BASE is updated to be defined as SOC_REGS_PHY_BASE.

Some now empty files are removed and the ternary license is replaced
with a SPDX GPL-2.0+ identifier.

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12+00:00

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.

arm: mvebu: correct comments around cas_wl/cas_l

2017-11-30T07:30:59+00:00

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.
