Like the other Logic PD OMAP35/DM37 boards, this board has device
tree enabled for U-Boot. This patch converts the board to enable
SPL_OF_CONTROL and further shrinks the device tree in SPL to limit
it to UART3 (console), MMC1, i2c1, and GPIO4 (for mmc1 CD and WP).
There appears to be a bug in minicom so users may need to
switch the minicom terminal emulation to ANSI from VT102 due
to the junk that gets pushed out of the UART on startup.

If UHS speed modes are enabled, a compatible SD card switches down to 1.8V
during enumeration. If after this a software reboot/crash takes place and
on-chip ROM tries to enumerate the SD card, the difference in
IO voltages (host @ 3.3V and card @ 1.8V) may end up damaging the card.
The fix for this is to have support for power cycling the card in
hardware (with a PORz/soft-reset line causing a power cycle of the card).
Because the beaglebone X15 (rev A,B and C), am57xx-evms and am57xx-idks don't
have this capability, disable voltage switching for these boards.
The major effect of this is that the maximum supported speed mode is now
high speed(50 MHz) down from SDR104(200 MHz).

Sync with kernel dts by adding pinmuxes for mmc1 and mmc2. This fixes an

During a short period when the bus voltage is switched from 3.3v to 1.8v,
(to enumerate UHS mode), the mmc module is disabled and the mmc IO lines
are kept in a state according to the programmed pad mux pull type.
According to 4.2.4.2 Timing to Switch Signal Voltage in "SD Specifications
Part 1 Physical Layer Specification Version 5.00 February 22, 2016", the
host should hold CLK low for at least 5ms.
In order to keep the card line low during voltage switch, the pad mux of
mmc1_clk line should be configured to pull down.
Add a new pinctrl group for clock line without pullup to be used in boards
where mmc1_clk line is not connected to an external pullup.

The LS1021A-TSN is a development board built by VVDN/Argonboards in
partnership with NXP.
It features the LS1021A SoC and the first-generation SJA1105T Ethernet
switch for prototyping implementations of a subset of IEEE 802.1 TSN
standards.
Supported boot media: microSD card (via SPL), QSPI flash.
Rev. A of the board uses a Spansion S25FL512S_256K serial flash, which
is 64 MB in size and has an erase sector size of 256KB (therefore,
flashing the RCW would erase part of U-Boot).
Rev. B and C of the board use a Spansion S25FL256S1 serial flash, which
is only 32 MB in size but has an erase sector size of 64KB (therefore
the RCW image can be flashed without erasing U-Boot).
To avoid the problems above, the U-Boot base address has been selected
at 0x100000 (the start of the 5th 256KB erase sector), which works for
all board revisions. Actually 0x40000 would have been enough, but
0x100000 is common for all Layerscape devices.
eTSEC3 is connecting directly to SJA1105 via an RGMII fixed-link, but
SJA1105 is currently not supported by uboot. Therefore, eTSEC3 is
disabled.
