79 prevent the driver of using the faster modes.
81 config SPL_MMC_IO_VOLTAGE
82 bool "Support IO voltage configuration in SPL"
85 IO voltage configuration allows selecting the voltage level of the IO
86 lines (not the level of main supply). This is required for UHS

127 bool "Tiny MMC framework in SPL"
129 Enable MMC framework tinification support. This option is useful if
130 if your SPL is extremely size constrained. Heed the warning, enable
131 this option if and only if you know exactly what you are doing, if
132 you are reading this help text, you most likely have no idea :-)
134 The MMC framework is reduced to bare minimum to be useful. No malloc
135 support is needed for the MMC framework operation with this option
136 enabled. The framework supports exactly one MMC device and exactly
137 one MMC driver. The MMC driver can be adjusted to avoid any malloc
138 operations too, which can remove the need for malloc support in SPL
139 and thus further reduce footprint.
