Subject: [POWERPC] bootwrapper: Add ppcboot.h
X-Git-Tag: v2.6.22-rc1~1109^2~58
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9b1c59e256e91aaf2a6543b32afc3658d8f96d4b;p=linux-2.6

[POWERPC] bootwrapper: Add ppcboot.h

This file describes the bd_t struct, which is used by old versions of
U-boot to pass information to the kernel.  Platform code that needs to
interoperate with such firmware can use this; it should not be used for
anything new.
