A walkthrough for microzed, OS = Kubuntu 14.04, gcc 4.8.4
Steps

1. Build and install toolchain with poky, instructions here.
Step 1: get source
git clone https://github.com/Xilinx/u-boot-xlnx.git

commit 40e8c28b90725f1e23e22c3b3514cf0b531f1bee Author: Michal Simek <michal.simek@xilinx.com> Date: Mon Jan 11 11:50:53 2016 +0100
Step 2: initenv
1. Create initenv in u-boot-xlnx:
initenv:
#!/bin/sh export CROSS_COMPILE=arm-poky-linux-gnueabi- export PATH=/opt/poky/2.0/sysroots/x86_64-pokysdk-linux/usr/bin/arm-poky-linux-gnueabi/:$PATH
2. run:
. ./initenv
Note: if forgotten the error would be something like this:
lib/asm-offsets.c:1:0: error: bad value (armv5) for -march= switch /* ^ make[1]: *** [lib/asm-offsets.s] Error 1 make: *** [prepare0] Error 2
Step 3: config
make zynq_microzed_defconfig
output:
HOSTCC scripts/basic/fixdep HOSTCC scripts/kconfig/conf.o SHIPPED scripts/kconfig/zconf.tab.c SHIPPED scripts/kconfig/zconf.lex.c SHIPPED scripts/kconfig/zconf.hash.c HOSTCC scripts/kconfig/zconf.tab.o HOSTLD scripts/kconfig/conf # # configuration written to .config #
Step 4: make
make
output:
arm-poky-linux-gnueabi-ld.bfd: cannot find -lgcc make[2]: *** [examples/standalone/hello_world] Error 1 make[1]: *** [examples/standalone] Error 2 make: *** [examples] Error 2
