Some SoCs in the mpc83xx family, e.g. mpc8309, have a dedicated spi chip select, SPISEL_BOOT, that is used by the boot code to boot from flash. This chip select will typically be used to select a SPI boot flash. The SPISEL_BOOT signal is controlled by a single bit in the SPI_CS register. Implement a gpio driver for the spi chip select register. This allows a spi driver capable of using gpios as chip select, to bind a chip select to SPISEL_BOOT. It may be a little odd to do this as a GPIO driver, since the signal is neither GP or I, but it is quite convenient to present it to the spi driver that way. The alternative it to teach mpc8xxx_spi to handle the SPISEL_BOOT signal itself (that is how it's done in the linux kernel, see commit 69b921acae8a) Signed-off-by: Klaus H.

README.zfs
This patch series adds support for ZFS listing and load to u-boot. To Enable zfs ls and load commands, modify the board specific config file with #define CONFIG_CMD_ZFS Steps to test: 1. After applying the patch, zfs specific commands can be seen in the boot loader prompt using UBOOT #help zfsload- load binary file from a ZFS file system zfsls - list files in a directory (default /) 2. To list the files in zfs pool, device or partition, execute zfsls <interface> <dev[:part]> [POOL/@/dir/file] For example: UBOOT #zfsls mmc 0:5 /rpool/@/usr/bin/ 3. To read and load a file from an ZFS formatted partition to RAM, execute zfsload <interface> <dev[:part]> [addr] [filename] [bytes] For example: UBOOT #zfsload mmc 2:2 0x30007fc0 /rpool/@/boot/uImage References : -- ZFS GRUB sources from Solaris GRUB-0.97 -- GRUB Bazaar repository Jorgen Lundman <lundman at lundman.net> 2012.
