Hi,
i make new attempt to change mediatek boards to OF_UPSTREAM because i found
out, that dtbo merging is now possible.
but i faced a problem:
e.g. BPI-R3 has 2 SPI-devices (nand,nor) on same spi switchable via hw. i need
both in dts to probe the right
device for linux and to allow install from sdmmc to both of these devices based
on hw switch.
currently in uboot the nor is device 0 (unit-address and reg) and nand is 1.
this does not work in linux, so i need a
way to overwrite the dtso from linux with the new values in uboot.
for dts there is a way using -u-boot.dtsi files...do they also work for dtso?
where do they need to be placed?
I don't understand the issue. Is there code we can look at?
Are you planning on using the exact same DT binary in U-Boot and Linux
kernel? Why does it matter to Linux that the NOR in U-Boot is device 0?
Cheers,
Quentin
