Subject: [PATCH 2/5] imx8mm-cl-iot-gate: Retrieve the DDR type from EEPROM
Date: Tue, 12 Apr 2022 20:44:48 +0200 (CEST) [thread overview]
Message-ID: <20220412184450.A9C0483ED5@phobos.denx.de> (raw)
In-Reply-To: <20220319122249.77456-2-festevam@gmail.com>
> From: Fabio Estevam <festevam@denx.de>
> Currently, the DDR type is retrieved by iteracting inside an array
> of possible DDR types.
> This may take saveral attempts, which slows the overall U-Boot process
> and does not provide a good user experience:

> DDRINFO(T): mr5-8 [ 0x5000010 ]
