Hi Albert,
I have observed an issue regarding u-boot relocation, it's working with _TEXT_BASE address but for other address in DDR it's not working. Stops at relocation offset.
I was trying this on both QEMU as well as real target.
Here are my findings: ----------------------------- VExpress# tftp 0x8000 u-boot.bin smc911x: detected LAN9118 controller smc911x: phy initialized smc911x: MAC 52:54:00:12:34:56 Using smc911x-0 device TFTP from server 192.168.0.3; our IP address is 192.168.0.4 Filename 'u-boot.bin'.

From the logs, it's unable to get the exact lr value a/f relocation
happens, due to that board_init_r not been called.
Could you please help me, Do I need to change any TEXT_BASE or liker script for this.?
I have analyzed and understood the code and seems to be some wired thing on start code. I found some hack for this, but does it a valid issue or did I make any mistake.
Request for your help.
Regards, Jagan.
