From 5cd372e170f1827164e3bd267dff80962ded49d6 Mon Sep 17 00:00:00 2001 From: Kristoffer Ericson Date: Mon, 20 Nov 2006 20:42:44 +0100 Subject: [ARM] 3936/1: [Jornada7xx] - No use for jornada720.h * We don't need this header anymore - there is no data we need to share this way. FB driver gets this data through a resources structure. MCU Driver api will go to a jornada720_mcu.h file.

These can be described simply as a log2 of their maximum size, along with the base address of the first region and the number of regions. The base address is already described by PHYS_PFN_OFFSET, and the number of regions via the MAX_NUMNODES and the number of online nodes. If we then supply the log2 of their maximum size, all the other discontigmem macros can move into generic code. There is one exception: lh7a40x seems to have a more complicated setup; this is left alone.
