[U-Boot] [PATCH 1/3] mmc: detect boot sectors using EXT_CSD_BOOT_MULT too
by Stephen Warren 07 Sep '12

07 Sep '12

From: Stephen Warren <swarren(a)nvidia.com> Some eMMC devices contain boot partitions, but do not set the PART_SUPPORT bit in EXT_CSD_PARTITIONING_SUPPORT. 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).

[U-Boot] [PATCH] lsxl: support power switch
by Michael Walle 03 Sep '12

03 Sep '12

This patch restores the Linkstation's original behaviour when powering off. Once the (soft) power switch is turned off, linux will reboot and the bootloader turns off HDD and USB power. Then it loops as long as the switch is in the off position, before continuing the boot process again. Additionally, this patch fixes the board function set_led(LED_OFF).
