[Buildroot] [PATCH 2/3] configs/freescale_imx31_3stack: Remove target

Currently this target fails to build:

arch/arm/mach-imx/built-in.o: In function `init_mmdc_lpddr2_settings':
platform-spi_imx.c:(.text+0x8f18): undefined reference to `imx6sll_lpddr2_freq_change'
arch/arm/mach-imx/built-in.o: In function `imx6ul_cpuidle_init':
platform-spi_imx.c:(.init.text+0x195c): undefined reference to `mx6ull_lpm_wfi_end'
platform-spi_imx.c:(.init.text+0x1960): undefined reference to `mx6ull_lpm_wfi_start'
platform-spi_imx.c:(.init.text+0x1964): undefined reference to `imx6ull_low_power_idle'
arch/arm/mach-imx/built-in.o: In function `imx6sl_init_late':
platform-spi_imx.c:(.init.text+0x56f0): undefined reference to `imx6sll_cpuidle_init'
Makefile:969: recipe for target 'vmlinux' failed

NXP 4.9 kernel does not properly support mx31, so better remove this target.

mx31_3stack board is currently supported in U-Boot and kernel mainline,
so if someone is interested on this board, then a target can be introduced
later which uses these mainline components.

Currently I do not have access to this board, so remove it its defconfig
for now.

-**************************************
-Freescale i.MX31 PDK development board
-**************************************
-
-This file documents the Buildroot support for the Freescale i.MX31 PDK in "3
-stack" configuration.
-
-The i.MX31 Product Development Kit (or PDK) is Freescale development board [1]
-based on the i.MX31 application processor [2].
-
-For more details on the i.MX31 PDK board, refer to the User's Guide [3].
-
-Build
-=====
-
-First, configure Buildroot for your i.MX31 PDK board:
-
-  make freescale_imx31_3stack_defconfig
-
-Build all components:
-
-  make
-
-You will find in ./output/images/ the following files:
-  - rootfs.cpio
-  - rootfs.cpio.gz
-  - rootfs.tar
-  - zImage
-
-The generated zImage does include the rootfs.
-
-Boot the PDK board
-==================
-
-The i.MX31 PDK contains a RedBoot bootloader in flash, which can be used to
-boot the newly created Buildroot images from the network.
-
-This necessitates to setup a TFTP server first. This setup is explained for
-example in Freescale i.MX31 PDK 1.5 Linux User's Guide [4].
-
-Here is a sample RedBoot configuration, for proper network boot of Buildroot on
-the i.MX31 PDK:
-
-    RedBoot> fconfig -l
-    Run script at boot: true
-    Boot script:
-    .. load -r -b 0x100000 zImage
-    .. exec -c "console=ttymxc0,115200"
-
-    Boot script timeout (1000ms resolution): 2
-    Use BOOTP for network configuration: false
-    Gateway IP address: <your gateway IP address>
-    Local IP address: <your PDK IP address>
-    Local IP address mask: 255.255.255.0
-    Default server IP address: <your TFTP server IP address>
-    Board specifics: 0
-    Console baud rate: 115200
-    Set eth0 network hardware address [MAC]: false
-    GDB connection port: 9000
-    Force console for special debug messages: false
-    Network debug at boot time: false
-
-Adapt those settings to your network configuration by replacing the appropriate
-network addresses where necessary.
-
-You might want to verify that your i.MX31 PDK switches settings are the correct
-ones for UART, power, boot mode, etc. Here is a reference switches
-configuration:
-
-    SW4
-    1   2   3   4   5   6   7  8
-    ON off off off off off off ON
-
-    SW5 SW6 SW7 SW8 SW9 SW10
-     0   1   0   0   0    0
-
-See the i.MX31 PDK Linux Quick Start Guide [5] for more details on the switches
-settings.
-
-Connect a serial terminal set to 115200n8 and power on the i.MX31 PDK board.
-Buildroot will present a login prompt on the serial port.
-
-Enjoy!
