Subject: [U-Boot] [PATCH] Bits reversed in ppc4xx.h
Date: Wed, 19 Nov 2008 11:03:49 -0500 [thread overview]
Message-ID: <492438E5.3050900@harris.com> (raw)
The bits in ppc440.h for the SDR0_DDRCFG register are incorrect. The
register is numbered in big-endian mode, so for example, the LT2 bit
(bit 23) should be represented as 0x00000100 rather than 0x01000000.
