[U-Boot] U-Boot 2015.10-rc3: ARM: Fails to build for LS1021A-TWR with GCC 5.2

[Krishnakar, Srikanth]

Hi All,

I am trying to build nor u-boot for freescale LS1021A-TWR board with GCC-5.2 toolchain and finding issues at "OBJCOPY" process, the same u-boot builds fine with GCC-4.9.x, I at following commit tag on denx u-boot:

commit 1fb8d7933924aa5deb7e722d64c1d9fc7f0b2b82

Error Observed: 

u-boot# make ARCH=arm ls1021atwr_nor_config

u-boot# make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- all

-------------------

NOTE: If I manually run the same objcopy command from shell then It is successful, but invoking it from Makefile is not working.

There is also a patch in tree to fix the u-boot size issue with modifying TEXT_BASE address :

1c69a51 arm: ls102xa: Adjust the load address of U-Boot for NOR boot

But still the error is observed.

What else could be causing this failure ? Any Inputs are highly appreciated.
