This is an RFC so far. I'd like people who have issues with newer linkers to test this patch.
It is intended for arm926ejs, so you might have to 'port' it to your own ARM architecture.
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.
Darius.
It has been roughly tested with ELDK 4.2 and CodeSourcery arm-2010q1-202; both seem to run rather properly (no NAND issue at startup, 'help' and commands seem to be there).
Amicalement, Albert.
