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?

This is how I responded to Fabio on the same query a few hours ago :)
- Turn on CONFIG_ARM_APPENDED_DTB and CONFIG_ARM_ATAG_DTB_COMPAT
- cat zImage mx27pdk.dtb > zImage_dtb
- Boot zImage_dtb as you do with zImage
Regards,
Shawn

Yes, see CONFIG_ARM_APPENDED_DTB and CONFIG_ARM_ATAG_DTB_COMPAT.
