From: Alison Wang Date: Wed, 3 Dec 2014 07:00:46 +0000 (+0800) Subject: ls102xa: qixis: Add CONFIG_QIXIS_I2C_ACCESS macro X-Git-Tag: v2015.01-rc4~29^2~20 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=2565d18de0c57d95b32686f11aa98fd40d8a7e26;p=u-boot ls102xa: qixis: Add CONFIG_QIXIS_I2C_ACCESS macro 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.
