mtd-utils: flash_erase: Fix output of offsets
Need to use unsigned arithmetic and a 64-bit cast in order to calculate and output the correct offset for eraseblocks at large offsets. Signed integer arithmetic does not produce the correct result "uint64_t" result, so for offsets over 2GB we get messages like: Erasing 512 Kibyte @ ffffffff83180000 -- 4308642136 % complete. Note that this error was not affecting proper erasure; it just produced incorrect status messages. Also, we should not add an extra eraseblock for the final status message; this gives misleading output when, for example, the following statement is executed: $ flash_erase /dev/mtd0 0 1 Erasing 512 Kibyte @ 80000 -- 100 % complete We aren't erasing at offset 0x80000; it should display offset 0.
