U-Boot typically tears down the display controller before handing
control over to Linux. On LCD displays disabling pixel clock leads to a
fading out effect with vertical/horizontal lines. Make sure to disable
back light before booting Linux.Signed-off-by: Gerard Salvatella

Commit 3f353ceccbbb ("vf610: refactor DDRMC code") changed on-die
termination (ODT) values from 120 Ohm to 60 Ohm and enabled a static
read/write leveling which has not been tested with this board. This
commit reverts both changes and makes sure that memory gets
initialized as it has been done before the mentioned commit.Fixes: 3f353ceccbbb ("vf610: refactor DDRMC code")

Rather than passing a hardcoded maxsize to the generic get_ram_size()
function use the i.MX 7 specific imx_ddr_size() function, which extracts
the memory size at runtime by reading the DDR controller registers.This is a purely cosmetic change as the generic get_ram_size() function
already took care of properly automatically detecting 256MB, 512MB or 1GB
modules.Signed-off-by: Fabio Estevam

This commit adds support for the Toradex Colibri iMX7D 1GB Computer
on Module. The module is very similar to the Colibri iMX7D 512MB
but uses eMMC instead of raw NAND. This patch introduces a new
board specific Kconfig symbol to select between the two flash
options.Signed-off-by: Stefan Agner

This makes sure that all Colibri iMX7 modules work with the
same timing. The changes are:
- Disable ODT on read (JEDEC standard JESD79-3F says in chapter
5.2.3 ODT during Reads: "As the DDR3 SDRAM can not terminate
and drive at the same time, RTT must be disabled at least half
a clock cycle..." and also MX7D SABRESD is disabling it)
This alone fixed memory issues for two Colibri iMX7 1GB modules
which showed issues before
- Make sure tRFC(min) is at least 260ns
- Make sure tRC is >50.625ns
- tRP needs to be >13.125ns, we can lower from 18.75ns to 15ns
- tFAW is not relevant, leave at resetSigned-off-by: Stefan Agner

Allow optionally bringing up the Apalis type specific 4 lane PCIe port
as well as the PCIe switch as found on the Apalis Evaluation board. In
order to avoid violating the PCIe reset timing do this by overriding the
tegra_pcie_board_port_reset() function. Note however that both the
Apalis type specific 4 lane PCIe port as well as the regular Apalis PCIe
port are also left disabled in the device tree by default.Signed-off-by: Marcel Ziswiler

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

In order that we can use eth_env_* even when CONFIG_NET isn't set, move
these functions to environment code from net code.This fixes failures such as:
board/ti/am335x/built-in.o: In function `board_late_init':
board/ti/am335x/board.c:752: undefined reference to `eth_env_set_enetaddr'
u-boot/board/ti/am335x/board.c:766: undefined reference to `eth_env_set_enetaddr'which caters for use cases such as:
commit f411b5cca48f ("board: am335x: Always set eth/eth1addr environment
variable")when Ethernet is required in Linux, but not U-Boot.
