[PATCH 2/3] [v3] davinci: da850-dm646x: remove the SRAM_VIRT iotable entry

Ben Gardiner bengardiner at nanometrics.ca
Wed Jun 1 11:03:24 EDT 2011


The sram regions defined for da850-dm646x in their iotable entries are also
defined in their davinci_soc_info's.

Remove this duplicate information which is now uneccessary since sram
init will ioremap the regions defined by their davinci_soc_info's.

Since this removal completely removes all uses of SRAM_VIRT, also remove
the SRAM_VIRT definition.
