[Buildroot] [PATCH v2] board/freescale: switch create-boot-sd.sh to parted

[Vincent Stehlé]

Starting with version 2.26, sfdisk defaults to a unit of 512 B sectors.
With those recent versions of sfdisk, the create-boot-sd.sh script ends
up creating a boot partition of 240 KB, which is too small to contain a
Linux kernel.

As it is difficult to address both pre and post v2.26 sfdisk versions in
a single command, we change the create-boot-sd.sh script to use parted
instead. While at it, we set the boot partition size to 64 MB, which
should be enough for everyone.

Hi,

This is a second proposal, using parted this time. Even with sfdisk
`--unit' parameter, I could not find an eleguant solution to support all
versions of sfdisk, sorry. Please let me know if you find switching to
parted acceptable.

This is tested on Sabre AI with an i.MX6 Quad.

Best regards,

V.


Changes in v2
-------------
- Switch to parted, as advised by Gary.
- Fix spelling in commit message, spotted by Luca.
