82 config SPL_MMC_IO_VOLTAGE
83 bool "Support IO voltage configuration in SPL"

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