Hi,
Here's a patch to support SMC 9194 in our target (SuperH architecture,
which uses 16-bit I/O). This patch are made by Takeshi Yaegashi
<t@keshi.org>, I'm sending this to you on behalf of him, as SuperH
arch maintainer.
This patch consists three parts:
(1) Undef USE_32_BIT when __sh__ (SuperH) is defined.
Maybe this should be config option.
(2) Don't assume IRQ2 means IRQ9, this is PC only semantics.
(3) Bug fix of !USE_32_BIT. It seems it's paren-mismatch typo.
