From ada9318252f51c2626e9837c623f9812b0308dea Mon Sep 17 00:00:00 2001 From: Yoshihiro Shimoda Date: Tue, 3 Mar 2009 15:11:17 +0900 Subject: [PATCH] sh: Add support 32-Bit Extended Address Mode to sh7785lcr We can built 'make sh7785lcr_32bit_config'. And add new command "pmb" for this mode. This command changes PMB for using 512MB system memory.
