[yocto] binutils 2.29.1 ARM Thumb kernel problem

[Chris Elledge]

If I have neither the +1 nor the ORR then the kernel boot does this:

Loading file '/boot/gateway3.dtb' to addr 0x21000000 with size 28500
(0x00006f54)...
Done
Loading file '/boot/zImage' to addr 0x22000000 with size 3182128
(0x00308e30)...
Done
Kernel image @ 0x22000000 [ 0x000000 - 0x308e30 ]
## Flattened Device Tree blob at 21000000
   Booting using the fdt blob at 0x21000000
   Loading Device Tree to 3fe2f000, end 3fe38f53 ... OK

Starting kernel ...

and it stalls until the hardware watchdog trips 16 seconds later.
