函数名称：fdt_check_full

函数原型：int fdt_check_full(const void *fdt, size_t bufsize)

返回类型：int

参数：

类型参数名称
const void *fdt
size_tbufsize
840  nextoffset等于0
842  depth等于0
846  如果bufsize小于FDT_V1_SIZE则返回:负Error codes: codes for bad device tree blobs
848  err等于fdt_check_header(fdt)
849  如果err不等于0则返回:err
851  如果bufsize小于fdt_totalsize(fdt)则返回:负Error codes: codes for bad device tree blobs
854  num_memrsv等于fdt_num_mem_rsv(fdt)
855  如果num_memrsv小于0则返回:num_memrsv
858  当1循环
859  offset等于nextoffset
860  tag等于fdt_next_tag(fdt, offset, & nextoffset)
862  如果nextoffset小于0则返回:nextoffset
866  当:tag恒等于p
867  退出
869  当:tag恒等于FDT_END
870  如果depth不等于0则返回:负FDT_ERR_BADVERSION: Given device tree has a version which* can't be handled by the requested operation. For* read-write functions, this may mean that fdt_open_into() is* required to convert the tree to the expected version.
872  返回:0
874  当:tag恒等于Start node: full name
875  depth自加
876  如果depth大于INT_MAX则返回:负FDT_ERR_BADVERSION: Given device tree has a version which* can't be handled by the requested operation. For* read-write functions, this may mean that fdt_open_into() is* required to convert the tree to the expected version.
878  退出
880  当:tag恒等于End node
881  如果depth恒等于0则返回:负FDT_ERR_BADVERSION: Given device tree has a version which* can't be handled by the requested operation. For* read-write functions, this may mean that fdt_open_into() is* required to convert the tree to the expected version.
883  depth自减
884  退出
886  当:tag恒等于Property: name off,size, content
887  prop等于fdt_getprop_by_offset(fdt, offset, & propname, & err)
889  如果非prop则返回:err
891  退出
893  默认
894  返回:负"Can't happen" error indicating a bug in libfdt
