Subject: [prefix] Specify i486 architecture for LZMA decompressor
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=13c1abe10abd1c24307a6777b6cedfc5b46b088d;p=thirdparty%2Fipxe.git

[prefix] Specify i486 architecture for LZMA decompressor

The decompressor uses the i486 "bswap" instruction, but does not
require any instructions that exist only on i586 or above.  Update the
".arch" directive to reflect the requirements of the code as
implemented.
