Hi,
My U-boot is on an older version and that doesn't have DT support for ARM.
Now, is there any way of booting Linux with DT, without U-Boot supporting DT?
Like, if we can compile dtb somehow with Linux or something else?

Yes, see CONFIG_ARM_APPENDED_DTB and CONFIG_ARM_ATAG_DTB_COMPAT. Arnd ^ permalink raw reply [flat|nested] 5+ messages in thread
