Not to quibble, but see commit 74fac70084bb040342fafc3b0d2ef50fbe35646f: commit 74fac70084bb040342fafc3b0d2ef50fbe35646f Merge: 1bb5e90 8fd01b8 Author: Wolfgang Denk <[email protected]> Date: Tue Jul 19 22:27:07 2011 +0200 Merge branch 'master' of git://git.denx.de/u-boot-mmc * 'master' of git://git.denx.de/u-boot-mmc: mmc: rescan fails on empty slot AT91:mmc:fix multiple read/write error mmc: Access mode validation for eMMC cards > 2 GiB mmc: sh_mmcif: add support for Renesas MMCIF mmc: fix the condition for MMC version 4 MMC: add marvell sdhci driver MMC: add sdhci generic framework MMC: add erase function to both mmc and sd MMC: unify mmc read and write operation -> mmc: Tegra2: Enable SD/MMC driver for Seaboard and Harmony -> mmc: Tegra2: SD/MMC driver for Seaboard - eMMC on SDMMC4, SDIO on SDMMC3 It would appear that Wolfgang merged my changes into the master branch on July 19th, unless I'm misreading this. Note that I don't see any commit by me labeled "tegra2: Enable MMC for Seaboard" - I'm assuming you meant this one. > For Harmony you'll need my patch "tegra2: Move board_mmc_init into board > files", which is part of a series that's not yet merged. > > -- > nvpublic _______________________________________________ U-Boot mailing list [email protected] http://lists.denx.de/mailman/listinfo/u-boot
