[Arm-netbook] rhombus-tech wiki page for allwinner a10 kernel compile

Thu Dec 15 08:09:57 GMT 2011

Luke,

if you keep your finger down on the return key  answering the default to 
all questions...
...you don't get a kernel for the  AllWinner A10 Cortex A8 ARM v7  SoC   
but   a generic one for the generic ARM Versatile family V5

As I previously said  it seems  this kernel  is mispatched  ... and 
several Kconfig files must to be fixed

With the actual kernel  you get this config options....

scripts/kconfig/conf --silentoldconfig arch/arm/Kconfig

Any suggestions with the branch  name ??
