3b1f6811 caused a regression that removes

assumption that CONFIG_DISPLAY_BOARDINFO_LATE was the same thing as
CONFIG_DISPLAY_BOARDINFO.

Ventana needs to call show_board_info in late init because we need to have
the i2c eeprom based model info. Re-define CONFIG_DISPLAY_BOARDINFO_LATE
to allow that to happen.

The IMX6 PCIe host controller does not have a proper reset and as such there
are several issues that can arise if PCI is enabled in the bootloader follwed
by Linux trying to re-configure LTSSM and/or toggling PERST# to the devices.

For now, the best approach seems to default to disabling PCI by defaulting
pciedisable=1. This can be overridden by the user if they need PCI in the
bootloader, for example:
 - GW552x needing ethernet access in bootloader
 - GW16082 expansion board needing a device-tree fixup for irq mapping

Ventana boards with a PCI Marvell Sky2 GigE MAC require the MAC address to
be placed in a DT node in order for the mainline linux driver to obtain it.
Signed-off-by: NTim Harvey <tharvey@gateworks.com>

The GW16082 mini-PCI expansion mezzanine uses a TI XIO2001 PCIe-to-PCI
bridge with legacy INTA/B/C/D interrupts. These interrupts are assigned
in the reverse order according to the PCI spec.

If the TI bridge is found on the Ventana PCI bus, add device-tree nodes
according to bus enumeration explicitly defining the interrupt mapping
to override the default PCI mapping in the Linux kernel. This allows
the GW16082 to work with upstream kernels that support device-tree
irq parsing.

The cm-fx6 module has an on-board spi flash chip. Enable mtd support
and the mtdparts command. Also define a default partitioning, add
it to the default environment, and enable support to overwrite the
partitioning defined in a device tree by it. Finally, probe for the
chip on preboot to register the flash chip and, thus, establish the
connection between the mtd environment settings and the actual device.

These changes move the effective default partitioning from the device
tree shipped with the vendor kernels to U-Boot which becomes the single
point of definition for the partitioning for all device tree based
kernels (in particular, for the upstream Linux kernel which does not
have a default partitioning defined in its device tree).

Recently I started to notice that u-boot.img built for Wandboard
by some toolchains becomes so large that it basically overlaps with
U-Boot environment area on SD-card.

According to
http://wiki.wandboard.org/index.php/Boot-process#sdcard_boot_data_layout
Wandboard's SD-card layout is as follows:
------------------------------>8---------------------------
Acked-by: NOtavio Salvador <otavio@ossystems.com.br>
Acked-by: NFabio Estevam <fabio.estevam@nxp.com>

==========================================================
1. 0x00000000           Reserved For MBR
2. 0x00000200   512     Secondary Image Table (optional)
3. 0x00000400   1024    uBoot Image (Starting From IVT)
4. 0x00060000   393216  start of uboot env (size:8k)
5. 0x00062000           end of uboot env
6. 0x00100000   1048576 Linux kernel start
7. 0x0076AC00   7777280 start of partition 1
------------------------------>8---------------------------

So for U-Boot we have 383kB (392192 bytes).

But in up to date U-Boot for Wandboard we build separately
 a) SPL
 b) u-boot.img

which gives us a bit more detailed SD-card layout:
------------------------------>8---------------------------
==========================================================
1. 0x00000000           Reserved For MBR
2. 0x00000200   512     Secondary Image Table (optional)
3. 0x00000400   1024    SPL
4. 0x00011400   70656   u-boot.img
5. 0x00060000   393216  start of uboot env (size:8k)
6. 0x00062000           end of uboot env
...
------------------------------>8---------------------------

>From that layout we may calculate amount of space reserved for
u-boot.img. It's just 315kb (322560 bytes).

Now if I build U-Boot with Sourcery CodeBench ARM 2014.05 produced
u-boot.img is already more than we expected
(323840 bytes instead of "< 322560"):
------------------------------>8---------------------------
ls -la u-boot.img
-rw-rw-r-- 1 user user 323840 Jul  5 07:38 u-boot.img
------------------------------>8---------------------------

Funny enough if I rebuild U-Boot with ARM toolchain available in
my Fedora 23 distro u-boot.img becomes a little bit smaller:
------------------------------>8---------------------------
ls -la u-boot.img
-rw-rw-r-- 1 user user 322216 Jul  5 07:39 u-boot.img
------------------------------>8---------------------------

What's worse this problem might not affect people most of the time
because what happens people would just copy u-boot.img on SD-card and
live in happiness with it... well until somebody attempts to save
environment in U-Boot with "saveenv" command which will simply
overwrite the very end of u-boot.img.
That will lead to unusable SD-card until user dd u-boot.img on
SD-card again.

I may foresee this issue in the future to become more visible once we
add more features in U-Boot for Wandboard or just existing code base
becomes bulkier and people will consistently get larger u-boot.img
files produced.

IMHO there's an obvious solution for all that - just move U-Boot's env
to the very end of the gap between U-Boot and the first real partition
on the SD-card. This patch will follow
8fb9eea5 ("mx6sabre_common: Fix U-Boot corruption after 'saveenv'").
So env is still not in the very end of the gap (obviously 256kb is way
too much for U-Boot's env) but at least we have now the same
partitioning for i.MX6 boards.
