From 002dedc5e933f6683b48de2f5702089c65b86bd1 Mon Sep 17 00:00:00 2001 From: Rasmus Villemoes Date: Thu, 28 Nov 2019 15:55:36 +0100 Subject: [PATCH 1/1] serial: ucc_uart: stub out soft_uart_init for !CONFIG_PPC32 The Soft UART hack is only needed for some PPC-based SOCs. To allow building this driver for non-PPC, guard soft_uart_init() and its helpers by CONFIG_PPC32, and use a no-op soft_uart_init() otherwise.
