Tom, Thanks! I had a conversation with engineer who came up with new cache management framework. Looks like he has provided patch which fixes this Issue which got exposed because of his patches. I will test this patch Tomorrow and confirm. Most probably, we don't need this patch. Regards, Nag

Nick, I am seeing this issue on da830/da850/dm36x/dm644x. I agree that u-boot will be faster with cache enabled. And also, TI wants it to be enabled soon. Since so many patches are lined u, we don't up-streaming them to get hampered because of this issue. So, we are trying to push this Patch.

Mike, We will address cache coherency issues soon after these patches. Earlier also, chache was disabled. Only due to new cache management Framework which was added recently, it is explicitly needed to be indicated to turn off cache. Since fixing the cache coherency issues with EMAC will take

From: Nagabhushana Netagunte there are cache coherency issues when using the DAVINCI Ethernet driver, hence caches cant be used for da830 u-boot. As per new cache management framework,if the caches are not used in u-boot, it needs to be explicitly indicated through macros in config file. CACHE di
