Before change introduced in commit SHA1:c2dd0d45540397704de9b13287417d21049d34c6 the D-cache for GONI/Universal_c210 targets was disabled. This change was supposed to preserve this state. 2. I've done some investigation about enabling D-cache support. It turned out, that some drivers (which are already posted or are in the queue for posting to u-boot list) have had problems with D-cache coherency. This commit shall be treated as a temporal solution. After solving cache management (and coherency) problems the D-cache would be definitely enabled. -- Best regards, Lukasz Majewski Samsung Poland R&D Center Platform Group _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
