fdt_find_add_string_() - Find or allocate a string

@fdt: pointer to the device tree to check/adjust @s: string to find/add @allocated: Set to 0 if the string was found, 1 if not found and so allocated. Ignored if can_assume(NO_ROLLBACK)

Returns: offset of string in the string table (whether found or added)

fdt_add_mem_rsv - add one memory reserve map entry @fdt: pointer to the device tree blob @address: 64-bit start address of the reserve map entry @size: 64-bit size of the reserved region

Adds a reserve map entry to the given blob reserving a region at address address of length size.

This function will insert data into the reserve map and will therefore change the indexes of some entries in the table.

returns: 0, on success -FDT_ERR_NOSPACE, there is insufficient free space in the blob to contain the new reservation entry -FDT_ERR_BADMAGIC, -FDT_ERR_BADVERSION, -FDT_ERR_BADSTATE, -FDT_ERR_BADSTRUCTURE, -FDT_ERR_BADLAYOUT, -FDT_ERR_TRUNCATED, standard meanings

: entry to remove

fdt_del_mem_rsv() removes the n-th memory reserve map entry from the blob.

This function will delete data from the reservation table and will therefore change the indexes of some entries in the table.

returns: 0, on success -FDT_ERR_NOTFOUND, there is no entry of the given index (i.e. there are less than n+1 reserve map entries) -FDT_ERR_BADMAGIC, -FDT_ERR_BADVERSION, -FDT_ERR_BADSTATE, -FDT_ERR_BADSTRUCTURE, -FDT_ERR_BADLAYOUT, -FDT_ERR_TRUNCATED, standard meanings
