From 9eed1ca15b84202e1edf086ebe8c3584d711ed2e Mon Sep 17 00:00:00 2001 From: Adam Ford Date: Mon, 24 Jun 2019 11:57:25 -0500 Subject: [PATCH] ARM: am3517-evm: Migrate to SPL_OF_CONTROL Like the other Logic PD OMAP35/DM37 boards, this board has device tree enabled for U-Boot. This patch converts the board to enable SPL_OF_CONTROL and further shrinks the device tree in SPL to limit it to UART3 (console), MMC1, i2c1, and GPIO4 (for mmc1 CD and WP). There appears to be a bug in minicom so users may need to switch the minicom terminal emulation to ANSI from VT102 due to the junk that gets pushed out of the UART on startup.
