The IMX6 PCIe host controller does not have a proper reset and as such there

For now, the best approach seems to default to disabling PCI by defaulting

- GW552x needing ethernet access in bootloader

wandboard: move environment partition farther from u-boot.img
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: Otavio Salvador <otavio@ossystems.com.br> Acked-by: Fabio 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 8fb9eea5653796 ("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.

test/py: strip VT100 codes from match buffer
Prior to this patch, any VT100 codes emitted by U-Boot are considered part
of a command's output, which often causes tests to fail. For example,
test_env_echo_exists executes printenv, and then considers any text on a
line before an = sign as a valid U-Boot environment variable name. This
includes any VT100 codes emitted. When the test later attempts to use that
variable, the name would be invalid since it includes the VT100 codes.
Solve this by stripping VT100 codes from the match buffer, so they are
never seen by higher level test code.
The codes are still logged unmodified, so that users can expect U-Boot's
exact output without interference. This does clutter the log file a bit.
However, it allows users to see exactly what U-Boot emitted rather than a
modified version, which hopefully is better for debugging. It's also much
simpler to implement, since logging happens as soon as text is received,
and so stripping the VT100 codes from the log would require handling
reception and stripping of partial VT100 codes.

pci: tegra: actually program REFCLK_CFG* on recent SoCs
On recent SoCs, tegra_pcie_phy_enable() isn't called; but instead
tegra_pcie_enable_controller() calls tegra_xusb_phy_enable(). However,
part of tegra_pcie_phy_enable() needs to happen in all cases. Move that
code to tegra_pcie_port_enable() instead.
For reference, NVIDIA's downstream Linux kernel performs this operation
in tegra_pcie_enable_rp_features(), which is called immediately after
tegra_pcie_port_enable(). Since that function doesn't exist in the U-Boot
driver, we'll just add it to the tail of tegra_pcie_port_enable() instead.

pci: tegra: correctly program PADS_REFCLK registers
The value that should be programmed into the PADS_REFCLK register varies
per SoC. Fix the Tegra PCIe driver to program the correct values. Future
SoCs will require different values in cfg0/1, so the two values are stored
separately in the per-SoC data structures.
For reference, the values are all documented in NV bug 1771116 comment 20.
The Tegra210 value doesn't match the current TRM, but I've filed a bug to
get the TRM fixed. Earlier TRMs don't document the value this register
should contain, but the ASIC team has validated all these values, except
for the Tegra20 value which is simply left unchanged in this patch.

usb: dm: Make "usb info" use usb_for_each_root_dev()
The old dm "usb info" implementation has several issues:
1) NULL pointer deref when a bus has no children
2) Not showing usb devices on busses without an emulated root-hub (otg host)
3) Attempting to show devices on inactive busses
4) "usb info" Would cause some hosts to get re-probed something which only
"usb reset" should do
TL;DR: proper iterating over usb bus root devs is hard, use the helper
for it.

arc: Use "-mcpu=archs" instead of deprecated "-marchs" for ARC HS
Newer ARC toolchains don't support "-marchs" option any longer.
Instead "-mcpu=archs" should be used. What's also important older
toiolchains that support ARC HS cores will also happily accept
"-mcpu=archs" so that's a very safe move.
