The efi and efidebug commands each carried their own code for printing the EFI memory map, with separate tables of memory type and attribute names. The copies had drifted: efidebug knew EFI_PERSISTENT_MEMORY_TYPE while 'efi mem' printed it as '<invalid>', neither table knew EFI_UNACCEPTED_MEMORY_TYPE, and the 'efi mem' printer had misaligned column headers, a broken '<gap>' line and a superfluous Virtual column: the map is identity mapped before SetVirtualAddressMap() is called, so the field carries no information at the time the command can run. Move the printing loop of 'efidebug memmap' into efi_common.c as efi_show_memmap(), which is linked into both commands, and use it from both. The second copy in 'efi mem' is deleted together with efi_print_mem_table() and the private sorting and merging code, including the 'all' argument. The memory type names follow the UEFI specification with the leading 'Efi' and the trailing 'Type' stripped, for example ConventionalMemory for EfiConventionalMemory, and the missing name for unaccepted memory is added. The type column is widened to fit the longest name, MemoryMappedIOPortSpace. The shared function iterates the map with the descriptor size reported by the firmware instead of assuming sizeof(struct efi_mem_desc). This matters for 'efi mem' under EDK II based firmware, which reports a descriptor size of 0x30. The memory map key, which was printed uninitialized on the payload path, is now initialized. The command documentation is updated with output captured from the app running under OVMF, and documents why virtual addresses are not shown.

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.
