Hi Bin & Lukas
At the beginning, I really don't understand the fdt Usage:
Maybe I am not so familiar with fdt.
I can't find any string about fdt_blob. It seem not describe so clearly
After I trace fdt.c, I finally know to get it as below.
RISC-V # bdinfo
boot_params = 0x00000400
...
baudrate = 38400 bps
fdt_blob = 0x3FF0F340
RISC-V #
RISC-V # fdt addr -c
The address of the fdt is 0x3ff0f340
Usage:
fdt addr [-c] <addr> [<length>] - Set the [control] fdt location to <addr>
fdt move <fdt> <newaddr> <length> - Copy the fdt to <addr> and make it active
fdt resize [<extrasize>] - Resize fdt to size + padding to
4k addr + some optional <extrasize> if needed
fdt print <path> [<prop>] - Recursive print starting at <path>
fdt list <path> [<prop>] - Print one level starting at <path>
fdt get value <var> <path> <prop> - Get <property> and store in <var>
fdt get name <var> <path> <index> - Get name of node <index> and
store in <var>
fdt get addr <var> <path> <prop> - Get start address of <property>
and store in <var>
fdt get size <var> <path> [<prop>] - Get size of [<property>] or num
nodes and store in <var>
fdt set <path> <prop> [<val>] - Set <property> [to <val>]
fdt mknode <path> <node> - Create a new node after <path>
fdt rm <path> [<prop>] - Delete the node or <property>
fdt header - Display header info
fdt bootcpu <id> - Set boot cpuid
fdt memory <addr> <size> - Add/Update memory node
fdt rsvmem print - Show current mem reserves
fdt rsvmem add <addr> <size> - Add a mem reserve
fdt rsvmem delete <index> - Delete a mem reserves
fdt chosen [<start> <end>] - Add/update the /chosen branch in the tree
<start>/<end> - initrd start/end addr
It seem that other arch (MICROBLAZE, ARM) also print fdt_blob in bdinfo cmd.
So I think this patch can be accepted.
