Allow partition selection on such devices, by enabling partition switching when EXT_CSD_BOOT_MULT is set. Note that the Linux kernel enables access to boot partitions solely based on the value of EXT_CSD_BOOT_MULT; EXT_CSD_PARTITIONING_SUPPORT only influences access to "general" partitions. eMMC devices affected by this issue exist on various NVIDIA Tegra platforms (and presumably many others too), such as Harmony (plug-in eMMC), Seaboard, Springbank, and Whistler (plug-in eMMC).

da850/omap-l138: Add support to read u-boot image from MMC/SD 2012-09-01T12:58:09+00:00 Lad, Prabhakar prabhakar.lad@ti.com 2012-06-24T21:35:20+00:00 0d986e61e26280c93b7e261c98b1f606bb9ddc5a DA850/OMAP-L138 does not support strict MMC/SD boot mode. SPL will be in SPI flash and U-Boot image will be in MMC/SD card. SPL will do the low level initialization and then loads the u-boot image from MMC/SD card. Define CONFIG_SPL_MMC_LOAD macro in the DA850/OMAP-L138 configuration file to enable this feature.

mmc: Change board_mmc_getcd() function prototype. 2012-01-09T03:28:27+00:00 Thierry Reding thierry.reding@avionic-design.de 2012-01-02T01:15:36+00:00 314284b1567f1ce29c19060641e7f213146f7ab8 The new API no longer uses the extra cd parameter that was used to store the card presence state. Instead, this information is returned via the function's return value. board_mmc_getcd() returns -1 to indicate that no card-detection mechanism is implemented; 0 indicates that no card is present and 1 is returned if it was detected that a card is present. The rationale for this change can be found in the following email thread: http://lists.denx.de/pipermail/u-boot/2011-November/110180.html In summary, the old API was not consistent with the rest of the MMC API which always passes a struct mmc as the first parameter. Furthermore the cd parameter was used to mean "card absence" in some implementations and "card presence" in others.
