函数名称：fdt_resize

函数原型：int fdt_resize(void *fdt, void *buf, int bufsize)

返回类型：int

参数：

类型参数名称
void *fdt
void *buf
intbufsize
151  headsize等于fdt_off_dt_struct(fdt)加fdt_size_dt_struct(fdt)
152  tailsize等于fdt_size_dt_strings(fdt)
154  如果headsize加tailsize大于fdt_totalsize(fdt)则返回:负"Can't happen" error indicating a bug in libfdt
157  如果headsize加tailsize大于bufsize则返回:负FDT_ERR_EXISTS: Attempted to create a node or property which* already exists
160  oldtail等于fdt加fdt_totalsize(fdt)减tailsize
161  newtail等于buf加bufsize减tailsize
165  如果buf小于等于fdt则
166  Not static to avoid a conflict with the prototype in the Linux headers.
167  Not static to avoid a conflict with the prototype in the Linux headers.
168  否则
169  Not static to avoid a conflict with the prototype in the Linux headers.
170  Not static to avoid a conflict with the prototype in the Linux headers.
173  fdt_set_totalsize(buf, bufsize)
174  如果fdt_off_dt_strings(buf)则fdt_set_off_dt_strings(buf, bufsize)
177  返回:0
