Matt Weber b98e541413 configs/freescale_p1025twr_defconfig: new board
Replacing the p1010rdb, this board is based on the tower development
system still available by NXP. The board is setup to track upstream
Linux and has been bumped from 4.1 to 4.15 (compared to p1010).

The target does not build uboot and assumes the user still uses the NXP
suggested prebuilts in the SDK2.0 (last release for PowerPC). If a
uboot is required, the source for SDK2.0 can be found in the following
repo.

The bootloader is no longer buildable in the latest Freescale/NXP tree or
upstream.  As such, retrieve the "Image: SDK V1.2 e500v2 Binary ISO" from
NXP downloads and follow the release notes for reflashing.

For programming the kernel and rootfs created by buildroot into the flash.
The fast way is to tftp transfer the files via one of the network interfaces.
Make sure your devkit has ipaddr and serverip defined to reach your tftp
server.

(Assuming the default u-boot env from NXP)
1. Program the DTB to NOR flash

    => setenv dtbfile p1025twr.dtb
    => run dtbflash

2. Program the kernel and rootfs to NOR flash (reusing orignal rootfs
   NOR location, as the kernel location is to small)

    => tftpboot $loadaddr uImage; protect off 0xeeb80000 +$filesize; erase 0xeeb80000 +$filesize; cp.b $loadaddr 0xeeb80000 $filesize; protect on 0xeeb80000 +$filesize; cmp.b $loadaddr 0xefa80000 $filesize

3. Booting your new system

    => bootm 0xeeb80000 - 0xefe80000

    You can login with user "root".
