ARM: LPC32XX: Update PHY3250 MTD partition info

Adding the two other partitions of the phycore3250's nand flash:
u-boot and the u-boot environment partitions. The former can be useful if you are feeling adventurous and would like to upgrade u-boot. The later is very useful for userspace utilities like fw_setenv which can be used to modify the bootargs for the next reboot or insert many other useful scripts.

In addition, adding these partitions brings the mtdblock numbers back to what they were with the 2.6.27.8 release of the linux kernel shipped with the phycore3250 evm.

Hi Ben,

Thanks for posting these. The MTD support is currently only available on our GIT server, although we plan on getting the MTD patches into the mtd subtree soon..

This partitioning scheme isn't set it stone yet. We'll look at it again once we get those patches up for review.

Hi Ben,

Thanks for posting these. The MTD support is currently only available on our GIT server, although we plan on getting the MTD patches into the mtd subtree soon.. This partitioning scheme isn't set it stone yet. We'll look at it again once we get those patches up for review.

The last two offsets could just be:

? ? ? ?.offset = MTDPART_OFS_APPEND,

That way then automatically align to the next block offset. ?It's cleaner and will make changing the partitioning scheme easier.
