From 9948c521a63148e49d850d2ac760f245007908a3 Mon Sep 17 00:00:00 2001 From: Arthur Heymans Date: Mon, 24 Oct 2022 14:37:40 +0200 Subject: lib/coreboot_table: Simplify API to set up lb_serial Instead of having callbacks into serial console code to set up the coreboot table have the coreboot table code call IP specific code to get serial information. This makes it easier to reuse the information as the return value can be used in a different context (e.g. when filling in a FDT). This also removes boilerplate code to set up lb_console entries by setting entry based on the type in struct lb_uart.
