From: Jon Loeliger Date: Fri, 20 Oct 2006 20:50:15 +0000 (-0500) Subject: Converted all 85xx boards to use a common FSL I2C driver. X-Git-Tag: U-Boot-1_1_6~20^2~3^2^2 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=2047672684cf85cb6f96a1fbc993180aaaf19a99;p=u-boot Converted all 85xx boards to use a common FSL I2C driver. Introduced COFIG_FSL_I2C to select the common FSL I2C driver. And removed hard i2c path from a few u-boot.lds scipts too. Minor whitespace cleanups along the way.
