Add support for the NXP LS1021A-TSN board
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.

[Vladimir] Code taken from https://github.com/openil/u-boot (which
itself is mostly copied from ls1021a-iot) and adapted with the following
changes:
- Add a008850 errata workaround
- Converted eTSEC, MMC to DM to avoid all build warnings
- Plugged in distro boot feature, including support for extlinux.conf
- Added defconfig for QSPI boot
- Added the board/freescale/ls1021atsn/README.rst for initial setup
- Increased CONFIG_SYS_MONITOR_LEN so that the SPL malloc pool does not
get overwritten during copying of the u-boot.bin payload from MMC to
DDR.

+
+Compiling and flashing
+======================
+
+The LS1021A-TSN board comes along with a microSD card with OpenIL U-Boot that
+can be used to update its internal QSPI flash (which is empty out of the
+factory).
+
+To compile and flash an SD card image::
+
+ make ls1021atsn_sdcard_defconfig && make -j 8 && sudo cp u-boot-with-spl-pbl.bin /srv/tftpboot/
+ => tftp 0x82000000 u-boot-with-spl-pbl.bin && mmc rescan && mmc erase 8 0x1100 && mmc write 0x82000000 8 0x1100
+
+For the QSPI flash, first obtain the Reset Configuration Word binary for
+bootimg from the QSPI flash from the rcw project
+(https://source.codeaurora.org/external/qoriq/qoriq-components/rcw)::
+
+ make -j 8 && sudo cp ls1021atsn/SSR_PNS_30/rcw_1200_qspiboot.bin.swapped /srv/tftpboot/
+
+The above RCW binary takes care of swapping the QSPI AMBA memory, so that the
+U-Boot binary does not need to be swapped when flashing it.
+
+To compile and flash a U-Boot image for QSPI::
+
+ make ls1021atsn_qspi_defconfig && make -j 8 && sudo cp u-boot.bin /srv/tftpboot/
+
+Then optionally create a custom uboot-env.txt file (although the default
+environment already supports distro boot) and convert it to binary format::
+
+ mkenvimage -s 2M -o /srv/tftpboot/uboot-env.bin uboot-env.txt
+
+To program the QSPI flash with the images::
+
+ => tftp 0x82000000 rcw_1200_qspiboot.bin.swapped && sf probe && sf erase 0x0 +${filesize} && sf write 0x82000000 0x0 ${filesize}
+ => tftp 0x82000000 u-boot.bin && sf probe && sf erase 0x100000 +${filesize} && sf write 0x82000000 0x100000 ${filesize}
+ => tftp 0x82000000 uboot-env.bin && sf probe && sf erase 0x400000 +${filesize} && sf write 0x82000000 0x400000 ${filesize}
+
+The boards contain an AT24 I2C EEPROM that is supposed to hold the MAC
+addresses of the Ethernet interfaces, however the EEPROM comes blank out of
+the factory, and the MAC addresses are printed on a label on the bottom of
+the boards.
+
+To write the MAC addresses to the EEPROM, the following needs to be done once::
+
+ => mac id
+ => mac 0 00:1F:7B:xx:xx:xx
+ => mac 1 00:1F:7B:xx:xx:xx
+ => mac 2 00:1F:7B:xx:xx:xx
+ => mac save
+
+The switch ports do not have their own MAC address - they inherit it from the
+master enet2 port.
+
+Known issues and limitations
+============================
+
+- The 4 SJA1105 switch ports are not functional in U-Boot for now.
+- Since the IFC pins are multiplexed with QSPI on LS1021A, currently there is
+ no way to talk to the CPLD for e.g. running the "qixis_reset" command, or
+ turning the fan on, etc.
