board/freescale: single T1xxx/2xxx readme.txt

The readme.txt would contain similar content for either processor
family, so this patch consolidates the usage and adds the new
T2080 notes.

+For the bootloader, NXP has stablized at SDK2.0 (final release). It is
+suggested to download the prebuilt from NXP downloads and follow the
+release notes for reflashing.
+
+To program 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, netmask, and serverip defined to reach your
+tftp server. Verify bootargs are reasonable (console=ttyS0,115200).

+------------------------------------------------------------------------------
+
+Devkit: T1040RDB
+
+(Assuming the default u-boot env from NXP)
+1. Program the DTB to NOR flash
+
+    => tftpboot $loadaddr t1040d4rdb.dtb; protect off 0xe8800000 +$filesize; erase 0xe8800000 +$filesize; cp.b $loadaddr 0xe8800000 $filesize; protect on 0xe8800000 +$filesize; cmp.b $loadaddr 0xe8800000 $filesize
+
+2. Program the kernel and rootfs to NOR flash
+
+    => tftpboot $loadaddr uImage; protect off 0xe8020000 +$filesize; erase 0xe8020000 +$filesize; cp.b $loadaddr 0xe8020000 $filesize; protect on 0xe8020000 +$filesize; cmp.b $loadaddr 0xe8020000 $filesize
+    => tftpboot $loadaddr rootfs.cpio.uboot; protect off 0xe9300000 +$filesize; erase 0xe9300000 +$filesize; cp.b $loadaddr 0xe9300000 $filesize; protect on 0xe9300000 +$filesize; cmp.b $loadaddr 0xe9300000 $filesize
+
+3. Booting your new system
+
+    => boot
+
+    You can login with user "root".
+------------------------------------------------------------------------------
+
+Devkit: T2080 QDS or RDB
+
+(Assuming the default u-boot env from NXP)
+1. Netboot the kernel/rootfs/dtb
+
+    => tftp 0x1000000 uImage && tftp 0x2000000 rootfs.cpio.uboot
+
+    RDB => tftp 0x3000000 t2080rdb.dtb
+     or
+    QDS => tftp 0x3000000 t2080qds.dtb
+
+2. Booting your new system
+
+    => bootm 0x1000000 0x2000000 0x3000000
+
+    You can login with user "root".
+
+3. If flashing is desired, a similar approach to the T1040 can be followed
+   with updated addresses for the flash layout.  Example is in the NXP default
+   env.
