Subject: Handle 86xx SVR values according to the new Reference Manual.
X-Git-Tag: v2008.10-rc1~1125^2~1^2~20^2~1
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d14ba6a798beb753e7a864500414fcc2d198b8bc;p=platform%2Fkernel%2Fu-boot.git

Handle 86xx SVR values according to the new Reference Manual.
Both 8641 and 8641D have SVR == 0x8090, and are distinguished
by the byte in bits 16-23 instead.
Thanks to Jason Jin for noticing.
