Re: [U-Boot] [U-BOOT][PATCH] mmc: remove the hard setting for tran_speed

2012-04-02 Thread Jae hoon Chung
Hi Andy. How do you about this patch? I want to know your thinking. In my case, clock is set to 50MHz, but mmcinfo is produced the "25MHz". Because tran_speed is 25MHz. But mmc->card_caps is set to MMC_MODE_HS and MMC_MODE_HS_52MHZ. So we should be see the wrong information with mmcinfo. Best Reg

[U-Boot] [PATCH] mmc: modified calculated mmc-capacity & set mmc trans_speed

2010-04-07 Thread Jae hoon Chung
The patches do the following 1. If mmc size is more than 2GB , we need to calculated using the extended csd register. 2. mmc_set_clock() is hard setting, that is not good solution. If mmc is not MMC_MODE_HS, mmc will set card's trans_speed. Signed-off-by: Jaehoon Chung --- drivers/mmc/mmc.c |
