Re: [Ltib] mtd-utils: dependencies and versions

[Stuart Hughes]

Hi Joseph,

That sounds like a good idea.  Unfortunately it may be a while as I'm
working on something else right now and I'd like to make sure that I
test it carefully before replacing the old version.  In particular I'd
like to make sure whether or not the incidental patches are needed:

Patch1          : mtd-utils-20060302-cf-byteswap_h-1.patch
Patch2          : mtd-utils-20060302-find_fs_entry.patch
Patch3          : mtd-utils-20060302-eraseall.patch
Patch4          : mtd-utils-20060302-eraseall_prog.patch

BTW: the mtd-utils snapshot is from 20060302 in the spec file on
savannah:

Summary         : Memory Technology Device tools
Name            : mtd-utils
Version         : 20060302

is yours the same?

Regards, Stuart
