[U-Boot] checkarmreloc error for AArch64 (using vexpress_aemv8a_defconfig)

[Chou, David J]

Hello Albert,

Thanks for your quick response.  The error message disappeared after I switched to use gcc-linaro-aarch64-linux-gnu-4.8-2014.04_linux tool chain from Linaro in either u-boot-2015.07-rc2 branch or latest u-boot-2015.07 branch.  

I have one question: why the following  build generated a statically linked u-boot  as showed by "$ file u-boot" followed, and also it doesn't show "ARM" after " u-boot: ELF 64-bit LSB shared object," : 
$ make distclean
$ make vexpress_aemv8a_juno_defconfig ARCH=arm CROSS_COMPILE=aarch64-linux-gnu- 
$ make all ARCH=arm CROSS_COMPILE=aarch64-linux-gnu-
$ file u-boot
u-boot: ELF 64-bit LSB shared object, version 1 (SYSV), statically linked, not stripped

But when I built a 32-bit arm u-boot using following command, it generated a  dynamically linked u-boot, and  "file  u-boot" shows "ARM" after " u-boot: ELF 32-bit LSB shared object,":
$ make distclean
$ make vexpress_ca15_tc2_defconfig ARCH=arm CROSS_COMPILE=arm-eabi-  
$ make all ARCH=arm CROSS_COMPILE=arm-eabi-
$ file u-boot
u-boot: ELF 32-bit LSB shared object, ARM, version 1 (SYSV), dynamically linked (uses shared libs), not stripped

Is there anything wrong in my  commands (shown in following" again  to make a 64 bit aarch64 u-boot, what commands you use to generated 64 bits u-boot ?
$ make distclean
$ make vexpress_aemv8a_juno_defconfig ARCH=arm CROSS_COMPILE=aarch64-linux-gnu- 
$ make all ARCH=arm CROSS_COMPILE=aarch64-linux-gnu-

Is the 64bits u-boot you generated statically linked or dynamically linked when you use "file u-boot" to check it? Does "file u-boot" show "ARM" after " u-boot: ELF 64-bit LSB shared object,"?  Can you show the "file u-boot" result for your 64 bit u-boot?  

Thanks.

Best Regards,
David Chou

This error does not appear with the aarmch64 toolchain used by buildman or with the aarmch64 toolchain from Ubuntu repositories, either for
v2015.07-rc2 or for current top of branch u-boot[-arm]/master.

Is the code you are building pure v2015.07-rc3 or does it contain any local changes?
