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).
nits: U-Boot
Why don't you add a rule to scripts/checkpatch.pl that warns on improper spelling of U-Boot? It would save a lot of time on both ends.
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

+The LS1021A-TSN board comes along with a microSD card with OpenIL U-boot.
nits: U-Boot
+That will be used to update the internal QSPI flash, as well as
+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.
nits: U-Boot
+To compile and flash a U-boot image for QSPI::
ditto
- 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_1000_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.
