When CONFIG_LOG is activated, if LOG_DEBUG is defined in a file and DEBUG is not defined the trace with debug() macro are not displayed, because the parameter cond : _DEBUG = 0 is checked in debug_cond(). With this patch the define DEBUG, used to force the trace generated by debug() macro, is linked with the define LOG_DEBUG, used to force the trace generated by other macros (log_debug, dev_dbg, pr_debug). We only need to define LOG_DEBUG in a file to activate all the traces generated by any U-Boot debug macro, as it is described in /doc/develop/logging.rst Signed-off-by: Patrick Delaunay <patrick.delaunay@foss.st.com>
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.
