[PATCH 2/4] arm: dts: Enable NAND in DTS instead of DTSI

Daniel Schultz d.schultz at phytec.de
Mon Aug 21 23:44:05 PDT 2017


Starting with PCM-062, NAND isn't the main non-volatile memory for the
AM335x. Because that, NAND has be disabled in the SOM dtsi file and will
be enabled in a specific NAND SOM file.
