From 09a333ee3dbbc6cdd88830f5b68dc358cacb0093 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Tue, 30 Oct 2018 17:03:53 +0000 Subject: [PATCH] hw/ppc/ppc440_uc: Remove dead code in sdram_size() Coverity points out in CID 1390588 that the test for sh == 0 in sdram_size() can never fire, because we calculate sh with sh = 1024 - ((bcr >> 6) & 0x3ff); which must result in a value between 1 and 1024 inclusive. Without the relevant manual for the SoC, we're not completely sure of the correct behaviour here, but we can remove the dead code without changing how QEMU currently behaves.
