Add support for jumping to Linux kernel through OPTEE-OS on ARMv7a. This is only supported if U-Boot runs in PL1 secure. This change adds two components, one is fitImage OPTEE-OS loadable handler, which makes a note of OPTEE-OS being loaded and stores the load address for later jump to it. The second part is the actual jump to Linux through OPTEE-OS. The jump through OPTEE-OS requires set up of multiple CPU registers, r1 and r2 are passed through, r0 and r3 have to be set to 0, lr is set to Linux kernel entry point. This setup is done by new assembler function boot_jump_linux_via_optee(). The boot_jump_linux_via_optee() also includes STM32MP13xx late TZC configuration write, this cannot be moved easily, hence the ifdef. Signed-off-by: Marek Vasut <marek.vasut@mailbox.org>
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.
