4 bool "MMC/SD/SDIO card support"
5 default ARM || PPC || SANDBOX
7 This selects MultiMediaCard, Secure Digital and Secure
10 If you want MMC/SD/SDIO support, you should say Y here and
11 also to your specific host controller driver.
14 bool "Enable MMC controllers using Driver Model"
17 This enables the MultiMediaCard (MMC) uclass which supports MMC and
18 Secure Digital I/O (SDIO) cards. Both removable (SD, micro-SD, etc.)
19 and non-removable (e.g. eMMC chip) devices are supported. These
20 appear as block devices in U-Boot and can support filesystems such
24 bool "Enable MMC controllers using Driver Model in SPL"
25 depends on SPL_DM && DM_MMC
28 This enables the MultiMediaCard (MMC) uclass which supports MMC and
29 Secure Digital I/O (SDIO) cards. Both removable (SD, micro-SD, etc.)
30 and non-removable (e.g. eMMC chip) devices are supported. These
31 appear as block devices in U-Boot and can support filesystems such
37 bool "Tiny MMC framework in SPL"
39 Enable MMC framework tinification support. This option is useful if
40 if your SPL is extremely size constrained. Heed the warning, enable
41 this option if and only if you know exactly what you are doing, if
42 you are reading this help text, you most likely have no idea :-)
44 The MMC framework is reduced to bare minimum to be useful. No malloc
45 support is needed for the MMC framework operation with this option
46 enabled. The framework supports exactly one MMC device and exactly
47 one MMC driver. The MMC driver can be adjusted to avoid any malloc
48 operations too, which can remove the need for malloc support in SPL
49 and thus further reduce footprint.
