| Subject: cris: Only build flash rescue image if CONFIG_ETRAX_AXISFLASHMAP is |
| selected |
| |
| commit 328cf6927bb72cadefddebbc9a23c793108147a2 upstream. |
| |
| If CONFIG_ETRAX_AXISFLASHMAP is not configured, the flash rescue image |
| object file is empty. With recent versions of binutils, this results |
| in the following build error. |
| |
| cris-linux-objcopy: error: |
| the input file 'arch/cris/boot/rescue/rescue.o' has no sections |
| |
| This is seen, for example, when trying to build cris:allnoconfig |
| with recently generated toolchains. |
| |
| Since it does not make sense to build a flash rescue image if there is |
| no flash, only build it if CONFIG_ETRAX_AXISFLASHMAP is enabled. |
