e2162d709f imx: Remove boolean parameter from wdog powerdown function
imx_set_wdog_powerdown() is always used to disable the power down
enable bit, so remove the boolean parameter of the function.

It is also a bit strange to write a boolean value into registers,
so this new version makes explicit that we are writing 0.

While at it, rename it to imx_wdog_disable_powerdown().

b2e6ad451b mx51: Select the ESDHC_A001 erratum
When a high speed card is connected to mx51evk the following error is seen:

U-Boot 2017.11-rc2 (Oct 18 2017 - 13:49:26 -0200)

Err:   serial
Net:   FEC

The root cause for the failure is the eSDHC-A001 erratum:

"eSDHC-A001 : Data timeout counter (SYSCTL[DTOCV]) is not reliable for
values of 0x4,0x8, and 0xC" that is listed
on some PowerArchitecture chips:
https://www.nxp.com/files-static/32bit/doc/errata/MPC8379ECE.pdf

Even though eSDHC-A001 is not documented on the i.MX51 errata document,
I have confirmed with the NXP design team that this erratum does affect
i.MX51, so fix the problem by selecting SYS_FSL_ERRATUM_ESDHC_A001
at SoC level.

The i.MX51 ts4800 board already selects this option, but it is better
to move this selection to the i.MX51 SoC level instead.

07df697e14 mx25: Move MX25 selection to Kconfig
The motivation for moving MX25 selection to Kconfig is to be
able to better handle MX25 specific errata, so that an errata option
can be selected at SoC level instead of board level.

This selection method also aligns with the way other i.MX SoCs are
selected in U-Boot.

e203dcf23e imx_common: detect USB serial downloader reliably
The current mechanism using SCR/GPR registers work well when
the serial downloader boot mode has been selected explicitly
(either via boot mode pins or using bmode command). However,
in case the system entered boot ROM due to unbootable primary
boot devices (e.g. empty eMMC), the SPL fails to detect that
it has been downloaded through serial loader and tries to
continue booting from eMMC:
  Trying to boot from MMC1
  mmc_load_image_raw_sector: mmc block read error
  SPL: failed to boot from all boot devices
  ### ERROR ### Please RESET the board ###

The only known way to reliably detect USB serial downloader
is by checking the USB PHY receiver block power state...

962c78b1df imx: use BOOT_DEVICE_BOARD instead of UART
i.MX 6 serial downloader is not necessarily booting via UART but can
also boot from USB. In fact only some i.MX chips have serial
downloader support via UART (e.g. 6UL/ULL and Vybrid) but all of
them have serial downloader support via USB. Use the more appropriate
BOOT_DEVICE_BOARD define which is used for ROM provided recovery
mechanisms in general.

Also replace BMODE_UART with BMODE_RESERVED, which is more appropriate.
Commit 96aac843b6 ("imx: Use IMX6_BMODE_* macros instead of numericals")
added macros for boot modes, in the process the reserved boot mode got
named BMODE_UART. We use the reserved boot mode in the bmode command to
let the boot ROM enter serial downloader recovery mode. But this is only
a side effect, the actual boot mode is reserved...

Until these limitations are removed we cannot really support more than one
environment location. Adjust the location to be a choice so that only one
can be selected. By default the environment is 'nowhere', meaning that the
environment exists only in memory and cannot be saved.

Also expand the help for the 'nowhere' option and move it to the top since

2be296538e Convert CONFIG_ENV_IS_IN_MMC/NAND/UBI and NOWHERE to Kconfig
This converts the following to Kconfig:
   CONFIG_ENV_IS_IN_MMC
   CONFIG_ENV_IS_IN_NAND
   CONFIG_ENV_IS_IN_UBI
   CONFIG_ENV_IS_NOWHERE

In fact this already exists for sunxi as a 'choice' config. However not
all the choices are available in Kconfig yet so we cannot use that. It
would lead to more than one option being set.

In addition, one purpose of this series is to allow the environment to be
stored in more than one place. So the existing choice is converted to a
normal config allowing each option to be set independently.

There are not many opportunities for Kconfig updates to reduce the size of
this patch. This was tested with

   ./tools/moveconfig.py -i CONFIG_ENV_IS_IN_MMC

And then manual updates.  This is because for CHAIN_OF_TRUST boards they
can only have ENV_IS_NOWHERE set, so we enforce that via Kconfig logic
now.

552a848e4f imx: reorganize IMX code as other SOCs
Change is consistent with other SOCs and it is in preparation
for adding SOMs. SOC's related files are moved from cpu/ to
mach-imx/<SOC>.

This change is also coherent with the structure in kernel.
