The GARDENA smart Gateway boards are equipped with an Atmel / Microchip
AT91SAM9G25 SoC and with 128 MiB of RAM and 256 MiB of NAND storage.
This patch adds support for this board including SPL support. Therefore
the AT91Boostrap is not needed on this platform any more.

This patch moves all instances of static "watchdog_dev" declarations to
the "data" section. This may be needed, as the BSS may not be cleared
in the early U-Boot phase, where watchdog_reset() is already beeing
called. This may result in incorrect pointer access, as the check to
"!watchdog_dev" in watchdog_reset() may not be true and the function
may continue to run.

Since commit 9e3c0174 ("pico-imx7d: Add LCD support") we started to
notice some hangs in U-Boot.

There is not an issue on such commit per se, but due to the LCD support
the current drawn is increased and this may cause issues when powering
pico-imx7d-pi from USB.

Some computers may be a bit strict with USB current draw and will
shut down their ports if the draw is too high.

The solution for that is to use an externally powered USB hub between the
board and the host computer.

Add such recommendation to the README file.

After the DM_MMC conversion the following eMMC boot error is observed:

U-Boot SPL 2019.04-rc4 (Mar 20 2019 - 18:53:28 +0000)
Trying to boot from MMC1
MMC Device 0 not found
spl: could not find mmc device 0. error: -19
SPL: failed to boot from all boot devices
### ERROR ### Please RESET the board ###

This happens because the SPL code does not initialize the SDHC pins
and clock.

Fix it by moving the original eMMC initialization from U-Boot proper
to SPL.

On AXS10x boards we have non-standard NAND controller
which was never really used a lot as there're other much more
convenient [as they are standard & removable] persistent media
like SD-card and USB mass storage.

Moreover after recent changes we face with some NAND controller
runtime issues. So instead of keeping support of yet another
non-standard peripheral we're dropping its support for good.

required.

Reformat the document, adding a description of how to boot from SPI-NOR
and adding a brief description of how to recover the board should the
SPI-NOR be corrupted using imx_loader.

The third parameter of the pmic_clrsetbits() function is the mask
to the register and the correct mask is 1 not 0.

Since the LDOGCTL only contains a single valid bit (bit 0),
we can use pmic_reg_write() and write 1 directly, which fixes
the problem in a simpler way and use the original pmic function
that was used prior to the DM PMIC conversion.
