Subject: [PATCH 1/1] Zynq: add support to chainload another barebox
Date: Mon, 3 May 2021 10:07:30 +0000
Message-ID: <AM9P192MB0870CBDAD8B3CC328A1C2D6CAB5B9@AM9P192MB0870.EURP192.PROD.OUTLOOK.COM> (raw)
Since OCRAM is only 192K this introduces CONFIG_ZYNQ_BUILD_FSBL so we can can chainload a more feature rich barebox via bootm.
