From 89cdb6af04c16c5476221b1f2d25d8337ebbb391 Mon Sep 17 00:00:00 2001 From: balrog Date: Mon, 2 Jun 2008 01:33:11 +0000 Subject: [PATCH] Provide basic emulation for Sharp SL-6000 PDA (Tosa), Dmitry Baryshkov. This adds basic support for emulating Sharp Zaurus SL-6000 PDA (tosa). Currently it provides only basic support: no kbd/lcd, sound, ts, etc. But it's able at least to boot Linux from CF.
