Subject: [patch 2/8] SDHCI: Print ADMA status and pointer on debug
Date: Tue, 02 Dec 2008 15:40:20 +0000 [thread overview]
Message-ID: <20081202154112.156260170@fluff.org.uk> (raw)
In-Reply-To: 20081202154018.906091477@fluff.org.uk
[-- Attachment #1: simtec/s3c64xx/sdhci-print-adma-status-if-enabled.patch --]
[-- Type: text/plain, Size: 863 bytes --]
If using ADMA, then we should print the ADMA error
and current pointer in sdhci_dumpregs() when any
debug is requested.
