component: sdio: fix potential ricky clock setting

2020-03-16T06:45:41Z

Currently RTT mmc stack only support Highspeed mode or blow, which means the max speed should be 52MHz according to JEDEC spec. Two problems show here: (1) max_data_rate = (unsigned int)-1. The value of unsigned int depends on compilers/arch. Moreover, it makes no sense to assume cpu addressing width with IP clock rate limit. (1)hs_max_data_rate was set to 200MHz. So what should BSP drivers do if 52MHz < max_data_rate < 200MHz? Either it blindly sets a spec-violated clock rate to drive a Highspeed card, or just adjust the clock rate internally. Both cases are really bad for practice. If the card claims to support Highspeed, we set the clock to not to exceed 52MHz. Otherwise it should be set according to card->max_data_rate parsed by ext_csd. This patch fixes it as-is, and also simplify the code a lot. Signed-off-by: Shawn Lin

[Components] sdio: try bus width depends on host's capability

2020-03-12T01:00:41Z

It makes no sense to try bus width if not supported by drivers or BSP, since we know it must be failed. It saves a lot for booting in time critical environment. Signed-off-by: Shawn Lin

[component] sdio: Fix mmc mount function if the whole device is a partition

2020-03-12T01:00:33Z

If the whole sd card was formatted as a partition, current code break out the loop mistakenly, so it skips dfs_mount_device later. Simply remove the broken 'break' to solve this problem. Signed-off-by: Shawn Lin
