* mmc: add the MMC_CLK_ENABLE/DISABLE macro in mmc.hJaehoon Chung2018-05-081-0/+3
| | | | | | | | | | | mmc_set_clock() function has the disable argument as bool type. When mmc_set_clock is called, it might be passed to "true" or "false". But it's too confusion whether clock is enabled or disabled with only "true" and "false". To prevent the confusion, replace to MMC_CLK_ENABLE/DISABLE macro from true/false.

* SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini2018-05-071-2/+1
| | | | | | | | | | | | | | | | | | | | When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
* mmc: fix bug in mmc_startup_v4()Jean-Jacques Hiblot2018-02-191-0/+1
| | | | | | | | | | | | | | The correspondence between mmc versions as used in u-boot and the version numbers reported in register EXT_CSD_REV is wrong for versions above and including MMC_VERSION_4_41. All those versions were shifted by one: real 4.5 hardware appeared to be MMC_VERSION_5_0. Fix this by adding the missing version in the correspondence table.

| | | | | | | | | | | | | | | | With certain SD cards like Kingston 8GB/16GB UHS card, it is seen that MMC_CMD_ALL_SEND_CID cmd fails on first attempt, but succeeds subsequently. Therefore, retry MMC_CMD_ALL_SEND_CID cmd a few time as done in Linux kernel. Similarly, it is seen that MMC_CMD_SET_BLOCKLEN may fail on first attempt, therefore retry this cmd a few times as done in kernel. To make it clear that those are optionnal workarounds, a new Kconfig option 'MMC_QUIRKS' is added (enabled by default).

|/ | | | | | | | | | | | | | At present if U-Boot proper uses driver model for MMC, then SPL has to also. While this is desirable, it places a significant barrier to moving to driver model in some cases. For example, with a space-constrained SPL it may be necessary to enable CONFIG_SPL_OF_PLATDATA which involves adjusting some drivers. Add new SPL versions of the options for DM_MMC, DM_MMC_OPS and BLK. By default these follow their non-SPL versions, but this can be changed by boards which need it.
