Later Colibri iMX7D V1.1B modules are using a “new” SoC fusing. The
difference has to do with whether or not we do enable the boot ROM to
enable/use the eMMC reset signal. Depending on that SoC fuse, the boot
ROM configures this pin as a GPIO output to actually be able to do/drive
the reset signal. Our eMMC vs. NAND detection so far only sets that
signal to a GPIO but without explicitly setting any direction as, of
course, so far, by default, it was an input. As the boot ROM now sets
it as an output we do get back a value of zero instead of a one which
would indicate the pull-up being present on eMMC modules.
Fix this by setting the SION bit which allows reading back the value
even if it is set to be an output by the boot ROM. Note that with the
new SoC fusing we now read back what the boot ROM drived rather than
the real value caused by the pull-up resistor. However, if it would
ever be driven low the eMMC would anyway permanently be reset.

now that it is possible to use regulator-fixed-clock make use
of it. This makes U-Boot detect the PHY on first cold-boot.
This commit also adjusts the code in setup_fec and follows
how it is done in mx6ullevk.c
This commit also slows down the boot-process by about 150ms
as it now waits for the regulator-fixed-clock voltage that
drives the PHY to go up.
If you rely on very fast boot-speeds and don't need ethernet
for your boot-process you can safely revert the changes on
imx6ull-colibri.dtsi

Toradex uses the variable variant to distinguish between modules with eMMC,
NAND with wifi and NAND without wifi.
This variable is set on every boot. Set this variable also if we have a NAND
module without wifi to prevent issues.

NXP used to setup the gpmi clock root from gpmi_clk in early versions in their
downstream BSP. [1]
However on mainline the gpmi clock root was always setup from enfc since the
beginning of the i.MX 6 series SoCs, which is still the same today. [2]
NXP followed the mainline approach at some point and changed setup_gpmi_io_clk
to setup gpmi clock root from enfc which left faulty code behind in our board
file. [3]
This commit follows the change of NXP as it improves the performance of the NAND
from ~1.2 MiB/s to ~12 MiB/s. [3]
This change was verified to work in recovery-mode and u-boot loaded from NAND on
all four Colibri iMX6ULL SKUs from Toradex.
The frequency used to read the NAND, measured on RE# (Read Enable):
before this patch: 1.4 MHz
after this patch: 22 MHz
in Linux Kernel: 50 MHz

This configuration creates an U-Boot which does not use any storage
device, i.e. no eMMC or NAND. It is used to boot U-Boot over recovery
aka. Serial Downloader without the need to know if the module
uses eMMC or NAND for storage. It detects the storage device type and
start the Toradex Easy Installer with the matching configuration.
Note that for NAND devices the mtd partitioning is not patched into
the device tree by U-Boot. It must be part of the provided device
tree.

This introduces support for EEPROM as a storage for the main Toradex

carrier board or video adapters).
To enable EEPROM as a storage for the main config block:
TDX_HAVE_EEPROM=y.
For additional EEPROMs please enable this Kconfig symbol:
TDX_CFG_BLOCK_EXTRA=y.
Information about existing EEPROM chips is provided via Device Tree
using aliases.
You can also write configuration for the carrier board using
create_carrier subcommand for cfgblock. Example:
Verdin iMX8MM # cfgblock create_carrier
Supported carrier boards:
UNKNOWN CARRIER = [0]
Verdin Carrier Board = [1]
Choose your carrier board (provide ID): 1
Enter carrier board version (e.g. V1.1B): V1.0A

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.

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
