Subject: [U-Boot] [PATCH v4 6/9] ls102xa: qixis: Add CONFIG_QIXIS_I2C_ACCESS macro
Date: Wed, 3 Dec 2014 15:00:46 +0800	[thread overview]
Message-ID: <1417590049-500-7-git-send-email-b18965@freescale.com> (raw)
In-Reply-To: <1417590049-500-1-git-send-email-b18965@freescale.com>

Through adding CONFIG_QIXIS_I2C_ACCESS macro,
QIXIS_READ(reg)/QIXIS_WRITE(reg, value) can be used
for both i2c and ifc access to QIXIS FPGA. This is
more convenient for coding.
