95bae9ff92 imx7: ccm: correct target interface num
According to i.MX 7Dual Applications Processor Reference Manual, Rev. 1
The target interface CCM root index ranges [0,124], so the number
should be 125.

cb82ee25f7 ARM: imx: ddr: Fill in missing DDRC ZQCTLx on i.MX7
The iMX7 defines further DDRC ZQCTLx registers, however those were
thus far missing from the list of registers and not programmed. On
systems with LPDDR2 or DDR3, those registers must be programmed with
correct values, otherwise the DRAM may not work. However, existing
systems which worked without programming these registers before are
now setting those registers to 0, which is the default value, so no
functional change there.

0e06d63d19 ARM: imx: ddr: Add missing PHY reset
The iMX7D RM 9.2.4.9.3 Power removal flow Table 9-11. Re-enabling power
explicitly says both the DDR controller and the PHY must be reset in the
correct sequence. Currently the code only resets the controller. This
leads to a misbehavior where the system brings the DRAM up after reboot,
but the DRAM is unstable. Add the missing reset.

The easiest way to trigger this is by triggering WDT without having the
WDT assert WDOG_B signal, i.e. mw.w 0x30280000 0x25 .

c3dc39a2f8 arm: Don't include common.h in header files
It is bad practice to include common.h in other header files since it can
bring in any number of superfluous definitions. It implies that some C
files don't include it and thus may be missing CONFIG options that are set
up by that file. The C files should include these themselves.

Update some header files in arch/arm to drop this.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
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.

067716bac5 ARM: Move SYS_CACHELINE_SIZE over to Kconfig
This series moves the CONFIG_SYS_CACHELINE_SIZE.  First, in nearly all
cases we are mirroring the values used by the Linux Kernel here.  Also,
so long as (and in this case, it is true) we implement flushes in hunks
that are no larger than the smallest implementation (and given that we
mirror the Linux Kernel, again we are fine) it is OK to align higher.
The biggest changes here are that we always use 64 bytes for CPU_V7 even
if for example the underlying core is only 32 bytes (this mirrors
Linux).  Second, we say ARM64 uses 64 bytes not 128 (as found in the
Linux Kernel) as we do not need multi-platform support (to this degree)
and only the Cavium ThunderX 88xx series has a use for such large
alignment.

1fb5133395 imx: iomux-v3: fix UART input selects
Several UART input selects are missing. The fourth input select
for UART2_TX_DATA_ALT0 is actually also missing in the documentation.
(at least in Rev. B of the i.MX 7Dual Reference Manual). However,
when looking at the tables of other input selects, it is very natural
that there must be an input select for the UART2_TX_DATA_ALT0 pad.
The Colibri iMX7 also uses that pad for UART2 RX (in DTE mode), and
it was required to set that particular input select register to get a
working UART2.

03f0e4c7cd imx: iomux-v3: add imx7d support for iomuxc
* Add imx7d support for iomux controller
* imx7d has two iomux controllers iomuxc (0x3033000) and iomuxc-lpsr
  (0x302C0000) each conroller provides control and mux mode pad
  registers but shares iomuxc input select register with iomuxc-lpsr
  IOMUX_CONFIG_LPSR flag is used to properly set daisy chain settings
  for iomuxc-lpsr pads.
* Since mx7d introduces LPSR IOMUX pins, add new base to IOMUX v3
  driver for these LPSR pins.
