bootm: booting of uncompressed uimages broken

[Hubert Feurstein]

Hi,

booting of uncompressed uimages is broken since patch "ARM: bootm: fix
default uImage placement" (0839e3f402ffc74202a1ca4fbeaffcadb4336ce1):

This is the change causing the issue:

  return ret;

  /*

- * risk to put it outside of lowmem.
+ * put oftree/initrd close behind compressed kernel image to avoid
+ * placing it outside of the kernels lowmem.

- mem_free = mem_start + SZ_128M;
- else
- mem_free = PAGE_ALIGN(data->os_res->end + SZ_1M);

  return __do_bootm_linux(data, mem_free, 0);
 }

System Info: iMX6S; 512MB RAM; LoadAddress 0x10008000; Barebox v2015.06.0
