Subject: [U-Boot] [PATCH v5 18/18] sf_probe: Extend the SPI NOR protection for SST flashes
Date: Mon,  2 Nov 2015 21:38:46 -0200	[thread overview]
Message-ID: <1446507526-7789-18-git-send-email-festevam@gmail.com> (raw)
In-Reply-To: <1446507526-7789-1-git-send-email-festevam@gmail.com>

From: Fabio Estevam <fabio.estevam@freescale.com>

SST flashes have a similar SPI NOR protection scheme as STMICRO, so 
add support for it.
