From 9af9c6bdc16da53772c56b1a79c2c91701fe94e6 Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Wed, 15 Jul 2009 13:45:00 -0500 Subject: [PATCH] 86xx: Report which "bank" of NOR flash we are booting from on MPC8641HPCN The MPC8641HPCN board is capable of swizzling the upper address bit of the NOR flash we boot out of which creates the concept of "virtual" banks. This is useful in that we can flash a test of image of u-boot and reset to one of the virtual banks while still maintaining a working image in "bank 0". The PIXIS FPGA exposes registers on LBC which we can use to determine which "bank" we are booting out of (as well as setting which bank to boot out of).
