65 This adds a command and an API to do hardware partitioning on eMMC
69 bool "Support IO voltage configuration"
71 IO voltage configuration allows selecting the voltage level of the IO
72 lines (not the level of main supply). This is required for UHS
73 support. For eMMC this not mandatory, but not enabling this option may
74 prevent the driver of using the faster modes.
76 config SPL_MMC_IO_VOLTAGE
77 bool "Support IO voltage configuration in SPL"
80 IO voltage configuration allows selecting the voltage level of the IO
81 lines (not the level of main supply). This is required for UHS

94 bool "enable UHS support in SPL"
95 depends on SPL_MMC_IO_VOLTAGE

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