From: York Sun Date: Thu, 2 Oct 2014 22:20:10 +0000 (-0700) Subject: common/board_r: Fix booting issue on T4240QDS X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=fef3e25fc3f59da6410878614e8717020a7d7f74;p=u-boot.git common/board_r: Fix booting issue on T4240QDS Commit 294b91a5817147d4b7f47be2ac69bac2a1f26491 moved initr_malloc earlier than initr_unlock_ram_in_cache. This causes issue on T4240. It may be related to locked L1 d-cache and unlocked L2 cache. D- cache could and should be unlock earlier for normal operation. This patch moves initr_unlock_ram_in_cache before initr_malloc. It has been verified on the following boards, in which only T4240QDS suffered and has been since fixed: T4240QDS, T2080QDS, P5040DS, P4080DS, MPC8572DS, MPC8536DS, MPC8641HPCN, B4860QDS.
