Fixes for 2021.1
----------------

CI: https://gitlab.denx.de/u-boot/custodians/u-boot-imx/-/pipelines/5680

- fixes for Variscite dart6ul
- imx8mp : increase malloc area
- fixes for bx50v3
- imx8m: HS400ES and UHS for EVK
- imx8qm-rom7720: fix phy bind

- Fix "Assert PERST# signal when unloading driver" in a37xx PCI
  driver (Pali)
- Fix SPL on armada-xp-gp (add u-boot,dm-pre-reloc and alias) (myself)

This reverts commit 828d3262.

This change revers code which asserting PERST# signal when unloading
driver. Driver's remove callback is still there as it is used for other
functionality.

Asserting PERST# signal prior booting kernel is causing that A3720 boards
(Turris MOX and Espressobin) with stable Linux kernel versions 4.14 and
4.19 are not able to detect some PCIe cards (e.g. Compex WLE200 and WLE900)
and anymore. When PERST# signal is not asserted these cards are detected
correctly. As this is regression for existing stable Linux kernel versions
revert this problematic change in U-Boot.

To make cards working with OpenWRT 4.14 kernel it is needed to disable link
training prior booting kernel, which is already done in driver's remove
callback.

Described issue is in Linux kernel pci aardvark driver which is (hopefully)
fixed in latest upstream versions. Latest upstream versions should be able
to initialize PCIe bus and detects cards independently of the link training
and PERST# signal state.

So with this change, U-Boot on A3720 boards should be able to boot OpenWRT
4.14 kernel, stable 4.14 and 4.19 kernels and also latest mainline kernels.

The dart6ul has an i2c eeprom at 0x50 which contains, among other
things, the manufacturing/revision/options info of the SoM. This patch
replaces the current checkboard() implementation with a more
exhaustive one based on the content of the eeprom.

Since this code uses the new driver model, some changes were also
required in the DTS to make the nodes related to i2c available before
relocation.

This code was inspired from the supported u-boot code from Variscite
which can be found here:

The current PHY rework does the following things:

1. Configure 125MHz clock
2. Setup the TX clock delay (RX is enabled by default),
3. Setup reserved bits to avoid voltage peak

The clock delays are nowadays already configured by the
PHY driver (in ar803x_delay_config). The code for that
can simply be dropped. The clock speed can also be
configured by the PHY driver by adding the device tree
property "qca,clk-out-frequency".

What is left is setting up the undocumented reserved bits
to avoid the voltage peak problem. I slightly improved its
documentation while updating the board's PHY rework code.

check for software being build with USE_HOSTCC without
relying on preprocessor conditions. In other words

 #ifdef USE_HOSTCC
 	host_only_code();

Some SD Card controller and power circuitry has increased capacitance,
which keeps the internal logic remains powered after regulator is switch
off. This is generally the case when card is switched to SD104 mode,
where a power cycle should be performed. In case if the card internal
logic remains powered, it causes a subsequent failure of mode
transition, effectively leading to failed enumeration.

Introduce a delay of 20 msec in order to provide a possibility for
internal card circuitry to drain voltages and perform a power cycle
correctly.

Similar fix is done in commit c49d0ac3 ("ARM: dts: rmobile: Increase
off-on delay on the SD Vcc regulator") targeted Renesas SOCs.
