[OpenWrt-Devel] [OpenWrt-Commits] r48276 - trunk/target/linux/ar71xx/image

[Arjen de Korte]

This doesn't look good. This patch will move the location of the  
'caldata_backup' partition from the factory default location

0x000001fc0000-0x000002000000 : "caldata_backup"

to

0x000007fc0000-0x000008000000 : "caldata_backup"

But since the data of this partition is not moved beforehand, the  
previous location will be overwritten by the larger "firmware"  
partition and the new location will probably contain nothing but FF.  
While I agree it is a waste to not use the 96 MB in location  
0x000002000000-0x000008000000, just moving the "caldata_backup"  
partition to a new location and hope for the best is not a good  
solution.

Regards, Arjen
