From 3b68d70dffe255e7681d5725d96bc2b92a24bb9d Mon Sep 17 00:00:00 2001 From: Lennert Buytenhek Date: Sun, 8 Jan 2006 01:01:11 -0800 Subject: [PATCH] cs89x0: cleanly implement ixdp2x01 and pnx0501 support Implement suitable versions of the readword/writeword macros for ixdp2x01 and pnx0501. Handle the 32-bit spacing of the registers in these functions instead of in the header file.
