From c94bc815f3c757df402d6f6a3e8d855b9168e6af Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Tue, 17 May 2016 17:15:33 +0200 Subject: [PATCH] ARM: shmobile: rcar-gen2: Use ICRAM1 for jump stub on all SoCs Currently the different SoCs in the R-Car Gen2 family use different types of on-chip RAM for the jump stub: - R-Car H2 uses Media RAM, - R-Car M2-W uses another type of optional On-chip RAM, as it doesn't have Media RAM, - R-Car M2-N uses Inter Connect RAM in Magnus Damm's "ARM: shmobile: r8a7793 boot address update". As all R-Car Gen2 SoCs have 4 KiB of Inter Connect RAM, consolidate the code by always using that.
