Subject: [PATCH] Use PVR to distinguish MPC5200B from MPC5200 in boot message
X-Git-Tag: v1.3.0-rc1~82
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a9d87e2707dcb249f6bb7f7ff7e00acd8cda9fd2;p=kernel%2Fu-boot.git

[PATCH] Use PVR to distinguish MPC5200B from MPC5200 in boot message

MPC5200B systems are incorrectly reported as MPC5200 in U-Boot start-up
message. Use PVR to distinguish between the two variants, and print proper CPU
information.
