Subject: [PATCH 0/4] arm: socfpga: mailbox_s10: cleanup and error handling
Date: Wed, 11 Mar 2026 12:06:38 +0100 [thread overview]
Message-ID: <20260311-agilex5-qspi-v1-0-be8a8e1318e1@pengutronix.de> (raw)
On Agilex 5, barebox uses the mailbox_s10 to gain access to the QSPI
flash. Depending on the system configuration, the SDM may deny this
access. barebox assumes that the access always works and surprisingly
fails, if this isn't the case. Add at least some error messages for this
situation.
While at it, cleanup the code to make it more readable and easier to
follow.
