90526e9fba common: Drop net.h from common header
Move this header out of the common header. Network support is used in
quite a few places but it still does not warrant blanket inclusion.

Note that this net.h header itself has quite a lot in it. It could be
split into the driver-mode support, functions, structures, checksumming,
etc.

f72e48ba4d board: apalis_imx6: Add KSZ9131 phy skew settings
This patch adds skew register settings for KSZ9131. It checks first
which phy is on the board and then applies the correct skew settings.

Skew settings calculation for the KSZ9131:
The i.MX6 SoC has an output skew tolerance of -100ps to 900ps. All
PCB traces where routed exactly the same length so we can calculate
the skew settings without taking the length into consideration. The
traces are all length matched.

RXC skew (PHY to MAC):
- We use the 2ns DLL controlled delay on the PHY
- We do not use the skew registers

This results in the following values:

		RXC
PHY fixed Delay	2000ps
PHY Added Delay	0ps
T_setup_R min	2.00ns
T_setup_R typ	2.00ns
T_setup_R max	2.00ns
T_hold_R min	1.60ns
T_hold_R typ	2.00ns
T_hold_R max	2.40ns

That means we are well within RGMII specs.

TXC skew (MAC to PHY):
- We use the 2ns DLL controlled delay on the PHY
- We then subtract ~0.6ns with TXD[0:3] and TXC clock pad skew
  register in a resulting ~1.4ns delay.

This results in the following values under consideration of the
tolerances:

		TXC min	TXC typ	TXC max
MAC min		-100ps	-100ps	-100ps
MAC max		900ps	900ps	900ps
PHY fixed Delay	2000ps	2000ps	2000ps
PHY added Delay	-340ps	-600ps	-859ps
T_setup_T min	1.56ns	1.30ns	1.04ns
T_setup_T typ	2.06ns	1.80ns	1.54ns
T_setup_T max	2.56ns	2.30ns	2.04ns
T_hold_T min	1.04ns	1.30ns	1.56ns
T_hold_T typ	1.94ns	2.20ns	2.46ns
T_hold_T max	2.84ns	3.10ns	3.36ns

This shows that T_hold_T min and T_setup_T min times are out of spec
for RGMII timing. However the KSZ9131 has a minimal value for this time
of 0.8ns which is met under all circumstances.

c4b650befc board: verdin-imx8mm: Add KSZ9131 phy skew settings
This patch determines which phy is placed on the board with the PHY ID
then it sets the same settings for KSZ9031 as before but for KSZ9131
it enables both RXC and TXC delay lines in the PHY.
This will compensate the missing delay from the MAC. Other skew
settings are not needed as the traces on board are routed exactly the
same length

b9bb1d06e2 imx: imx8m*: Remove do_reset from board files
Use the `do_reset` implementation of `arch/arm/lib/reset.c` in SPL
instead.  It is very close to what is done here, anyway, and plays
more nicely with the rest of U-Boot than adding a custom `do_reset`
implementation into board files.

`do_reset` from `arch/arm/lib/reset.c` calls `reset_cpu` with 0 as the
addr parameter while the boards are passing WDOG1_BASE_ADDR.  This is
ok because the `reset_cpu` implementation uses WDOG1_BASE_ADDR by
default if 0 is passed in.

This adds initial minimal support for the Toradex Verdin iMX8M Mini Quad
2GB WB IT V1.0A module. They are now strapped to boot from eFuses which
are factory fused to properly boot from their on-module eMMC. U-Boot
supports booting from the on-module eMMC only, SDP support is disabled
for now due to missing i.MX 8M Mini USB support.

Functionality wise the following is known to be working:
- eMMC, 8-bit and 4-bit MMC/SD card slots
- Ethernet
- GPIOs
- I2C

Boot sequence is:
SPL ---> ATF (TF-A) ---> U-boot proper

ATF, U-boot proper and u-boot.dtb images are packed into a FIT image,
loaded by SPL.

bfeaea7d84 colibri_imx6: fix broken fsl_esdhc_imx conversion
Not all CONFIG_FSL_ESDHC defines were properly replaced with
CONFIG_FSL_ESDHC_IMX, which broke U-boot proper booting on
Colibri iMX6 SoMs.

U-boot is stuck after this message:
Commercial temperature grade DDR3 timings, 64bit bus width.
Trying to boot from MMC1

bcee8d6764 dm: gpio: Allow control of GPIO uclass in SPL
At present if CONFIG_SPL_GPIO_SUPPORT is enabled then the GPIO uclass
is included in SPL/TPL without any control for boards. Some boards may
want to disable this to reduce code size where GPIOs are not needed in
SPL or TPL.

Add a new Kconfig option to permit this. Default it to 'y' so that
existing boards work correctly.

Change existing uses of CONFIG_DM_GPIO to CONFIG_IS_ENABLED(DM_GPIO) to
preserve the current behaviour. Also update the 74x164 GPIO driver since
it cannot build with SPL.

This allows us to remove the hacks in config_uncmd_spl.h and
Makefile.uncmd_spl (eventually those files should be removed).

c671d8af0b board: colibri_imx7: reserve DDR memory for Cortex-M4
i.MX 7's Cortex-M4 core can run from DDR and uses DDR memory for
the rpmsg communication. Both use cases need a fixed location of
memory reserved. For the rpmsg use case the reserved area needs
to be in sync with the kernel's hardcoded vring descriptor location.

Use the linux,usable-memory property to carve out 1MB of memory
in case the M4 core is running. Also make sure that the i.MX 7
specific rpmsg driver does not get loaded in case we do not carve
out memory.

afda2ace8a colibri_vf: use leveling evaluated by DDR validation tools
The DDR validation tool (which is part of Processor Expert) allows
to evaluate leveling parameters for CR105/CR106/CR110. Several
runs have been made with Colibri VF50 and VF61 and it seems to
evaluate very similar values. Use this values by default.

Note: The newly evaluated parameters seem to require CTLUPD_AREF
to be enabled!

Note 2: The tool also evaluated 6 as a new value for PHY02/18
GATE_CFG (Coarse adjust of gate open time). However, this seems
not to work in practise.

6218d4bdce colibri_imx6: revert fuse value set in mfgr_fuse
We have two commands to change the bootmode fuses:
mfgr_fuse which set fuse 0/5 and 0/6
and
updt_fuse which burns bit 4 of 0/5.

Before Image 2.6 we fused in mfgr_fuse 0x5062, which boots
from the user partition of the eMMC.
To workaround certain hangs we moved to fastboot mode and
using the first bootpartition of the eMMC requiring a fuse
value of 0x5072 which could be achived by the then added
updt_fuse command. At the same time the mfgr_fuse command
was changed to also fuse 0x5072, revert that second change
so that one can fuse both values, one with just mfgr_fuse
and the later with mfgr_fuse;updt_fuse.

Note that the mfgr_fuse command is only needed at module
production time, a customer might need to use updt_fuse
when upgrading an older module to be compatible with a
newer image. The command is integrated into the image
update scripts.

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.

a62c60610f colibri_imx7_emmc: add Colibri iMX7D 1GB (eMMC) module support
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.

a19797b22c colibri_imx7: improve DDR3 timing
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 reset

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

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.

9925f1dbc3 net: Move enetaddr env access code to env config instead of net config
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 f411b5cca4 ("board: am335x: Always set eth/eth1addr environment
variable")

when Ethernet is required in Linux, but not U-Boot.
