From b132eefc5f63412bb4a98a4bb72b9055e40d5d42 Mon Sep 17 00:00:00 2001 From: Keith Packard Date: Fri, 11 Nov 2011 22:30:17 -0800 Subject: altos: Make ao_xmem funcs require __xdata void * instead of casting Having an explicit cast in the ao_xmem wrapper macros caused the compiler to generate garbage values for pdata addresses, making the upper byte 0x00 instead of the required 0xf0. Removing the casts from the ao_xmem macros exposed this problem, so a new PDATA_TO_XDATA macros was added, along with a CODE_TO_XDATA macro which serve to cast pointers, with suitable address modifications, so that things work again.
