2018-01-12ARM: imx: cm_fx6: export board and soc info to envChristopher Spinrath
Like many other i.MX6 based boards, there are multiple variants of the cm-fx6 module featuring different SoC variants. Furthermore, the module can be paired with multiple baseboards. At the same time modern distribution like Fedora require U-Boot to select a proper devicetree which depends on the SoC variant and the baseboard. Thus, export the SoC variant and the actual board to the environment following the conventions of other i.MX6 devices (e.g. the NXP boards) such that the environment can select a devicetree file to load. For now, we only know for sure that the cm-fx6 module and the SB-fx6m baseboard amount to a Utilite Computer variant (depending on the SoC). Further combinations may be added in the future; e.g. CompuLab's evaluation board once someone can verify the identification string stored in its eeprom.

2018-01-12mmc: Retry some MMC cmds on failureKishon Vijay Abraham I
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).
