From 1f29cb19cb7c3bea870d7da02ec23823af9d636e Mon Sep 17 00:00:00 2001 From: Simon Arlott Date: Sun, 13 Dec 2015 22:47:55 +0000 Subject: [PATCH] MIPS: bcm963xx: Move extended flash address to bcm_tag header file The extended flash address needs to be subtracted from bcm_tag flash image offsets. Move this value to the bcm_tag header file. Renamed define name to consistently use bcm963xx for flash layout which should be considered a property of the board and not the SoC (i.e. bcm63xx could theoretically be used on a board without CFE or any flash).
