From 6eee21daf3d1cabad8a4dfaf6641d8845ee7578a Mon Sep 17 00:00:00 2001 From: Reinhard Arlt Date: Fri, 18 Nov 2011 09:06:52 +0000 Subject: [PATCH] bootvx: Clear and disable data cache, and call vxWorks with parameter. This patch clear and disable the data cache for vxWorks. The entry point sysInit(int) intended by Windriver to be called from the vxWorks bootrom, a very small vxWorks system. The routine is called by the go() handler in the bootrom, that clears the cache from start of image to end of usable memory. The PowerPC implementations only invalidates and disable the cache, the ARM implementations also flush it. U-Boot will be on the safe side, if it disables the data cache before calling vxWorks sysInit(int).
