No malloc 48 support is needed for the MMC framework operation with this option 49 enabled. The framework supports exactly one MMC device and exactly 50 one MMC driver. The MMC driver can be adjusted to avoid any malloc 51 operations too, which can remove the need for malloc support in SPL 52 and thus further reduce footprint. 53 54config MMC_DAVINCI 55 bool "TI DAVINCI Multimedia Card Interface support" 56 depends on ARCH_DAVINCI 57 default y 58 help 59 This selects the TI DAVINCI Multimedia card Interface. 60 If you have an DAVINCI board with a Multimedia Card slot, 61 say Y here.
