[U-Boot] [PATCH] ARM: zynq: Guard zynq_help_text with CONFIG_SYS_LONGHELP

[Michal Simek]

If SYS_LONGHELP is disabled the following warning is generated:
board/xilinx/zynq/cmds.c:496:13: warning: ‘zynq_help_text’ defined but
not used [-Wunused-variable]

Normal way for fixing this is to guard the whole variable.
