From dd332e18d082de75eca3fc2c7c778f5d4571a096 Mon Sep 17 00:00:00 2001 From: Anatolij Gustschin Date: Thu, 13 Nov 2008 18:08:57 +0100 Subject: [PATCH] 85xx: socrates: fix DDR SDRAM tlb entry configuration since commit be0bd8234b9777ecd63c4c686f72af070d886517 tlb entry for socrates DDR SDRAM will be reconfigured by setup_ddr_tlbs() from initdram() causing an inconsistency with previously configured DDR SDRAM tlb entry from tlb_table: socrates>l2cam 7 9 IDX PID EPN SIZE V TS RPN U0-U3 WIMGE UUUSSS 7 : 00 00000000 256MB V 0 -> 0_00000000 0000 -I-G- ---RWX 8 : 00 00000000 256MB V 0 -> 0_00000000 0000 ----- ---RWX 9 : 00 10000000 256MB V 0 -> 0_10000000 0000 ----- ---RWX This patch makes the presence of the DDR SDRAM tlb entry in the tlb_table dependent on CONFIG_SPD_EEPROM to avoid this inconsistency.
