Subject: [U-Boot] [PATCH] 83xx: correctly set encryption and I2C bus 0 clock
Date: Wed, 11 Mar 2009 08:27:24 +0100	[thread overview]
Message-ID: <49B767DC.7020205@aimvalley.nl> (raw)

This patch makes sure the correct mask is applied when setting
the encryption and I2C bus 0 clock in SCCR.
Failing to do so may lead to ENCCM being 0 in which case I2C bus 0
won't function.
