[PATCH] ARM: mach-ux500: enable 128KB way L2 cache on DB8540

From: Fabio Baltieri
Date: Wed Jan 23 2013 - 05:27:59 EST


From: Maxime Coquelin <maxime.coquelin@xxxxxxxxxxxxxx>

DB8540 L2 was configured with 64KB way size, but it has 128KB as AP9540.

Fix this by modifying ux500_l2x0_init() to use 128KB way size for all
cpus in the x540 family.
