arm/dt: consolidate atags setup into setup_machine_atags
In preparation for adding device tree support, this patch consolidates
all of the atag-specific setup into a single function.
v5: - drop double printk("Machine; %s\n", ...); call.
- leave copying boot_command_line in setup_arch() since it isn't
atags specific.
v4: - adapt to the removal of lookup_machine_type()
- break out dump of machine_desc table into dump_machine_table()
because the device tree probe code will use it.
- Add for_each_machine_desc() macro
