Subject: [U-Boot] [PATCH v5 06/16] ls102xa: esdhc: Add esdhc support for LS102xA
Date: Tue, 19 Aug 2014 10:54:55 +0800	[thread overview]
Message-ID: <1408416905-19771-7-git-send-email-b18965@freescale.com> (raw)
In-Reply-To: <1408416905-19771-1-git-send-email-b18965@freescale.com>

For LS102xA, the platform is little endian, while esdhc IP is
big endian. So two macros are added, CONFIG_SYS_FSL_ESDHC_LE
and CONFIG_SYS_FSL_ESDHC_BE, to determine the registers'
reading/writing in big or little endian format.
