Subject: [U-Boot] [PATCH v3] ATMEL: use generic mmc framework
Date: Sat, 10 Mar 2012 13:45:23 +0100 [thread overview]
Message-ID: <1331383523-23670-1-git-send-email-andreas.devel@googlemail.com> (raw)
In-Reply-To: <4F5B3A67.9030609@gmail.com>
From: Sven Schnelle <svens@stackframe.org>
gen_atmel_mci works on AVR32 as well, so no need to use the legacy
mmc driver. This also has the nice side effect of being able to use
SDHC cards an those boards.

changes since v2:
* remove board_mmc_init in atstk100x and atngw100 files in favour of
cpu_mmc_init
* add cpu_mmc_init to arch/avr32/lib/board.c
* add CONFIG_SYS_MMC_MAX_BLK_COUNT 1 to _every_ changed board config
* replace 'mmcinit' by 'mmc rescan' in provided environment
