Re-partitioning; Adding swap partition; Using GPT partitions

[Arwen]

I poked around at the location of the U-Boot code, and found I could increase the size of "/boot" as below. This gives me room for initial RAM disks and multiple kernels. Don't have a need for it, yet. But, had to learn what I could and could not do.

Here is what I currently have on my eMMC;

Code:

Device             Start       End   Sectors  Size Type
/dev/mmcblk1p1     32768   1081343   1048576  512M Linux filesystem
/dev/mmcblk1p2   1081344  13664255  12582912    6G Linux swap
/dev/mmcblk1p3  13664256  70705118  57040863 27.2G Linux filesystem
/dev/mmcblk1p4  70705152 127746014  57040863 27.2G Linux filesystem
/dev/mmcblk1p5 127746048 244277214 116531167 55.6G Linux filesystem

Edit: I also made "/boot" an EXT4 file system. It seems EXT4 on "/boot" is supported just fine. Don't know why FAT was used originally.
