In order to use the serial interface on the PortuxG20 we need to enable the
level converter first by setting the PC9 pin to high. The level converter needs
some time to settle so we have to use the mdelay() function to wait for some
time. Unfortunately we have no timers available at board_early_init_f() so we
enable the serial output early within board_postclk_init().
Now the U-Boot output looks fine:

This patch restores the Linkstation's original behaviour when powering off.
Once the (soft) power switch is turned off, linux will reboot and the
bootloader turns off HDD and USB power. Then it loops as long as the switch
is in the off position, before continuing the boot process again.
Additionally, this patch fixes the board function set_led(LED_OFF).

The fanless boards now have a 7-digit (XXXXX-F) board name. This
triggers a border condition when reading this string in the IVM although
this string is smaller than the currenly read string size, but only by 1
character.
This patch corrects this by changing the size check condition for string
length. It is the same change that was done in the platform for this
same bug.

The cache snooping feature of Freescale's eSDHC IP is not available on i.MX, so
disable it globally for this architecture. This avoids setting no_snoop for all
i.MX boards, and it prevents setting a reserved bit of a reserved register if
fsl_esdhc_mmc_init() is used on i.MX, like in
arch/arm/cpu/armv7/imx-common/cpu.c/cpu_mmc_init().
Since no_snoop was only used on i.MX, get rid of it BTW.

We have no idea where the DCD was derived from for Smartbook support, but they
differ from the Smarttop settings, MX51EVK settings and certainly don't
correspond to any shipped or development version of U-Boot that Genesi has ever
had on any Smartbook.
So, copy the calibrated, verified settings from the U-Boot as shipped with every
Smartbook since retail production. Remove those few settings that just set the
POR defaults which have already been confirmed for the previous Smarttop DCD
change.
One of the lines is specific to i.MX51 TO3 designs and therefore TO2 Smartbooks
will possibly not work so reliably with this new DCD; that said, TO2 Smartbooks
basically don't exist at retail and the number of units in the world is less
than 5 (3 of which are at the Genesi office or owned by Genesi employees).
Many hours of memory testing confirms the new settings are stable.

This is a rework of a previously submitted patchset and bundles the
main board support and USB support into a single commit.
It requires the patch "mx5: add iomux-mx51.h include"
* Use iomux-mx51.h include to simplify board configuration.
* Simplify LED support (remove efikamx_toggle_led, change lit LEDs).
* Simplify MMC support for CD and WP pin differences.
* Fix broken CPU voltage setting - comment said 1.1V but the code set to
1.2V. It should never have been set to 1.2V even on i.MX51 TO2 and
all available Linux kernels would drop the voltage to 1.1V anyway and
work reliably. This should lower power consumption during the boot
process.
* Function renames for readability.
* Some board identification string changes to match actual product names.
* Passes checkpatch (v2)

PCBID pads seem to need time to settle due to external pulldowns, otherwise
we are reading floating GPIO pins with implicit pad pullups and get the wrong
data. However we can't "wait" at the time we need them before relocation,
since timers are not available. The time taken to get from DCD to the code
requiring the pads set seems to be more than long enough (even with caches
enabled).
We have space in the DCD due to the DDR settings changes to configure all
the pad settings we need for this, plus the LED pad settings too which
reduces the amount of code required later on.

Efika MX boards configure their DDR pad settings twice, one in the DCD generated
from imximage_*.cfg and again in init_drive_strength called before relocation.
Rather than doing this, roll the changes it makes into the DCD so DDR is set up
before a single line of code in U-Boot is run.
The settings are identical with this DCD block which is shorter (by 7 entries)
than the old one, and after the output of init_drive_strength since a lot of the
functionality in the existing DCD and init_drive_strength function was just
setting the POR defaults. This goes to explain some now-missing entries.
Several hundred rounds of mtest have been run to test the settings before and
after to confirm DDR is stable and no ill-effects have been found.
