Subject: [PATCH 0/3] arm: socfpga: cleanup UART for serial console
Date: Fri, 05 Jun 2026 14:58:12 +0200	[thread overview]
Message-ID: <20260605-socfpga-debug-uart-v1-0-8454bfc709bf@pengutronix.de> (raw)

Configuring debug console output for the PBL and low level code on
SoCFPGA boards is surprisingly complex and an inconsistent configuration
bit me more than once.

Get rid of the custom UART implementation and the base addresses for the
debug UART in the barebox configuration.

While at it, set the debug UART for the Arrow AXE5 board in the board
code and don't force the developer to know and configure the correct
debug UART in the configuration.
