Thanks! It works on arm1176/mini6410 and solves problem of missing commands.
tested with gcc 4.4.5 + binutils 2.20.1 toolchain from Buildroot.
But it's strange, because I done the same test of declaring variable in
start.s:
.globl cmd_start
cmd_start:
.word __u_boot_cmd_start
Then disassembled elf shows it's value:
57e00048 <cmd_start>:
57e00048: 00000000 .word 0x00000000
Commands are there and somehow working, but at least it's very strange.
