Patch adds support for DaVinci DM365. It does not have the DM9000 like the DM355 but has capability for 4 BIT ECC correction just like DM355. This patch lacks 2 features
No 4 BIT ECC correction. We will add support for 4 BIT ECC correction to the NAND driver(davinci_nand.c) soon so that other device like the DM355 can also use this feature. Other TI SOCs like DA830(Primus) not yet part of the U-Boot GIT can also use this once support is added. Some core NAND driver APIs were changed and are being used by TI in our internal releases but those patches were not accepted when posted to the MTD list. So this support will have to wait for some time.
I have managed to get EMAC working in my branch but i see that there are patches where the location of the EMAC driver has changed along with a few other changes. The EMAC on all TI SOCs like DM644x, DM6467, DM365 and DA830 is simlar but not the same. So i need to come up with a patch which will enable EMAC to work on all TI SOCs.
Patches for the above features mentioned will be added soon. Patch for 4 BIT ECC correction and EMAC should not take much time to submit but the feature where we change the NAND read APIs to work along with the EMIF 2.3 IP present in latest DaVinci SOCs will take some time.
I'm not sure you really want all this comment will be in the final commit message
