[PATCH 1/3] ARM: ux500: Add device nodes for TCDM and TCPM memory locations

Lee Jones lee.jones at linaro.org
Mon Mar 25 11:02:36 EDT 2013


The PRCMU requires the Tightly Coupled Memory (TCM) locations in
order to function correctly. A recent move to send the base
addresses though the PRCMU platform device resource instead of
defines found in <mach/*>, means that dbx500 devices can no longer
boot successfully. These new nodes will allow the PRCMU to extract
the base memory locations from Device Tree instead.
