Subject: romlayout: Use .code16 not .code16gcc
X-Git-Tag: rel-1.8.0~136
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=5b22d9397258716bc2dc3b1b5a3f5cef297c6039;p=seabios.git

romlayout: Use .code16 not .code16gcc

There's no need to use .code16gcc where we are writing assembler code
explicitly. It only affects word-size-ambiguous instructions, and we
should just be explicit. And we are.
