Move (and rename) the following CONFIG options to Kconfig:
CONFIG_DAVINCI_MMC (renamed to CONFIG_MMC_DAVINCI)
CONFIG_OMAP_HSMMC (renamed to CONFIG_MMC_OMAP_HS)
CONFIG_MXC_MMC (renamed to CONFIG_MMC_MXC)
CONFIG_MXS_MMC (renamed to CONFIG_MMC_MXS)
CONFIG_TEGRA_MMC (renamed to CONFIG_MMC_SDHCI_TEGRA)
CONFIG_SUNXI_MMC (renamed to CONFIG_MMC_SUNXI)
They are the same option names as used in Linux.
This commit was created as follows:
[1] Rename the options with the following command:
find . -name .git -prune -o ! -path ./scripts/config_whitelist.txt \
-type f -print | xargs sed -i -e '
s/CONFIG_DAVINCI_MMC/CONFIG_MMC_DAVINCI/g
s/CONFIG_OMAP_HSMMC/CONFIG_MMC_OMAP_HS/g
s/CONFIG_MXC_MMC/CONFIG_MMC_MXC/g
s/CONFIG_MXS_MMC/CONFIG_MMC_MXS/g
s/CONFIG_TEGRA_MMC/CONFIG_MMC_SDHCI_TEGRA/g
s/CONFIG_SUNXI_MMC/CONFIG_MMC_SUNXI/g
'
[2] Commit the changes
[3] Create entries in driver/mmc/Kconfig.
(copied from Linux)
[4] Move the options with the following command
tools/moveconfig.py -y -r HEAD \
MMC_DAVINCI MMC_OMAP_HS MMC_MXC MMC_MXS MMC_SDHCI_TEGRA MMC_SUNXI
[5] Sort and align drivers/mmc/Makefile for readability
