### Description
I am testing NAND MTD partition in MIPS32 system, and after I created 4
partitions, I ran `cat /proc/partitions`, and got followings,
```
Name Start Size MTD
(noname) 34359738368 9230062565109792768
(noname) 274877906944 9230062565109792768
(noname) 274877906944 9230062565109792768
(noname) 274877906944 9230062565109792768
```
This is wrong, my partition table should be
```
Name Start Size MTD
(noname) 0 8 tstnand
(noname) 8 64 tstnand
(noname) 72 64 tstnand
(noname) 136 64 tstnand
```
The info is from following codes of `part_procfs_read()`,
```
#ifdef CONFIG_MTD_PARTITION_NAMES
ptr = attr->nextpart->name;
for (x = 0; x < sizeof(partname) - 1; x++)
{
/* Test for end of partition name */
if (*ptr == ',' || *ptr == '\0')
{
/* Perform space fill for alignment */
partname[x] = ' ';
}
else
{
/* Copy next byte of partition name */
partname[x] = *ptr++;
}
}
partname[x] = '\0';
/* Terminate the partition name and add to output buffer */
ret = snprintf(&buffer[total], buflen - total,
"%s%7ju %7ju %s\n",
partname,
(uintmax_t)attr->nextpart->firstblock / blkpererase,
(uintmax_t)attr->nextpart->geo.neraseblocks,
attr->nextpart->parent->name);
#else
ret = snprintf(&buffer[total], buflen - total, "%7ju %7ju %s\n",
(uintmax_t)attr->nextpart->firstblock / blkpererase,
(uintmax_t)attr->nextpart->geo.neraseblocks,
attr->nextpart->parent->name);
#endif
```
What is the right format should be used to print partition info across 32
and 64bit platform?
