soc_system_board_info.xml/hps_common_board_info.xml common accross most devboards ?

update : booting . but not really

or i should say not completely on my own //

i can create all it parts kernel/zImage/rootfs / boot.scr, soc_system.rbf, preloader-mkpimage.bin

but it only boots if i use the socfpga.dtb from the sdcard that came with it (posted on the terasic site) .. .

i have followed suggestions / remove second WDT, drop/disable peripherals in the soc_system.sopcinfo

i have converted / modified/ loaded generated dts files

i have unconverted the working blob to text& re'blob'ed it .. & it still boots

/ all others hang at "loading kernel ...."

I've requested any board*info.xml from Terasic -- they do provide a version for the De1-SOC

so it should not be a stretch for them to pass it on ---

obviously

the original device tree does me no good

it does not support the peripherals i've created

feeling some what stymied
