u-boot.git/drivers/mmc, branch v2012.07 Unnamed repository; edit this file 'description' to name the repository. FSL/eSDHC: enable the clock to detect the SD card 2012-07-13T22:04:50+00:00 Jerry Huang Chang-Ming.Huang@freescale.com 2012-05-17T23:57:02+00:00 975324a7d9abd26423594b596d8cd7b83699171a For FSL low-end processors (VVN2.2), in order to detect the SD card, we should enable PEREN, HCKEN and IPGEN to enable the clock. Otherwise, after booting the u-boot, and then inserting the SD card, the SD card can't be detected. For SDHC VVN2.3 IP, these bits are reserved, and SDCLKEN is used. And when accessing to these reserved bit, no any impact happened.

mmc:fix Call mmc_init() when executing mmc_get_dev() 2012-07-13T22:04:50+00:00 Łukasz Majewski l.majewski@samsung.com 2012-04-19T02:39:18+00:00 40242bc394030871e6de13883fe1ace5c0b8e15b This code adds call to mmc_init(), for partition related commands (e.g. fatls, fatinfo etc.). It is safe to call mmc_init() multiple times since mmc->has_init flag prevents from multiple initialization. The FAT related code calls get_dev high level method and then uses elements from mmc->block_dev, which is uninitialized until the mmc_init (and thereof mmc_startup) is called.
