[PATCH 11/11] ARM: at91: switch Calao QIL-A9260 board to DT

[nicolas.ferre@atmel.com (Nicolas Ferre)]

On 15/11/2013 15:50, Jean-Christophe PLAGNIOL-VILLARD :
> Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com>
> Cc: Nicolas Ferre <nicolas.ferre@atmel.com>

I corrected several errors: for other patches please check that the same
errors are not applying:
- typo in file header: s/Caloa/Calao/
- DT nodes in address ascending order
- incomplete command line:
  1/ no "mem" parameter, please
  2/ ubi rootfs specification parameters not complete
- node addresses for MTD partitions not aligned with node name
  (I mean, part after the @)

I will not do the same for other patches. So if you identify such
errors, please correct them...

Bye,
