Add Arm FF-A support implementing Arm Firmware Framework for Armv8-A v1.0 The Firmware Framework for Arm A-profile processors (FF-A v1.0) [1] describes interfaces (ABIs) that standardize communication between the Secure World and Normal World leveraging TrustZone technology. This driver uses 64-bit registers as per SMCCCv1.2 spec and comes on top of the SMCCC layer. The driver provides the FF-A ABIs needed for querying the FF-A framework from the secure world. The driver uses SMC32 calling convention which means using the first 32-bit data of the Xn registers. All supported ABIs come with their 32-bit version except FFA_RXTX_MAP which has 64-bit version supported. Both 32-bit and 64-bit direct messaging are supported which allows both 32-bit and 64-bit clients to use the FF-A bus. FF-A is a discoverable bus and similar to architecture features. FF-A bus is discovered using ARM_SMCCC_FEATURES mechanism performed by the PSCI driver. Clients are able to probe then use the FF-A bus by calling the DM class searching APIs (e.g: uclass_first_device). The Secure World is considered as one entity to communicate with using the FF-A bus. FF-A communication is handled by one device and one instance (the bus). This FF-A driver takes care of all the interactions between Normal world and Secure World. The driver exports its operations to be used by upper layers. Exported operations: - ffa_partition_info_get - ffa_sync_send_receive - ffa_rxtx_unmap Generic FF-A methods are implemented in the Uclass (arm-ffa-uclass.c). Arm specific methods are implemented in the Arm driver (arm-ffa.c). For more details please refer to the driver documentation [2].

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.
