Subject: Add a dumpdata() routing that will dump out an area of memory in
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=1dfc8279154d8221fb8fb9ba889ccbadc238f774;p=users%2Frw%2Fppcboot.git

Add a dumpdata() routing that will dump out an area of memory in
hex values along with addresses.
Also, rearrange and correct the setting of BCSR bits for FADS when
initializing the ethernet.
