From 6610b2e387113ae131eb837680fe2478b863f8b2 Mon Sep 17 00:00:00 2001 From: Chanh Nguyen Date: Sun, 10 Oct 2021 12:11:16 +0700 Subject: u-boot-aspeed: Add distro feature to enable SPI master mode The ast2500 shares the RGMII1 pin and the hw strap pins for SPI interface mode selection ( pin[12:13] ). In some systems, the RGMII/NCSI interface will use the pin. It makes the SPI interface mode setting is not correct. This patch adds a distro feature to enable the SPI master mode by default.
