From 5917bfa4c0c529d7a93323671f2edec7e3d81c07 Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Mon, 2 Jan 2012 22:57:03 -0500 Subject: [PATCH] ARM: mach-shmobile: use standard 2MiB coherent DMA memory size The 158MiB memory area was used to support HD resolution multimedia workloads using the same legacy memory allocating solution as on SH. There are no in-tree kernel dependencies on the 158MiB setting, and future development should reserve and allocate memory using some other method like for instance CMA.
