During LPDDR initialization we will loop through a series of frequency
changes in order to train at the various operating frequencies. During
this training, accessing the DRAM_CLASS bitfield could happen during a
frequency change and cause the read to hang.
Store the DRAM type into the main structure to avoid multiple readings
while the independent phy is training.

AM62x SoC is available in multiple variant:
- CPU cores (Cortex-A) AM62x1 (1 core), AM62x2 (2 cores), AM62x4 (4 cores)
- GPU AM625x with GPU, AM623x without GPU
- PRU (Programmable RT unit) can be present or not on AM62x2/AM62x4
Remove the relevant FDT nodes by reading the actual configuration
from the SoC registers, with that change is possible to have a single
dts/dtb file handling the different variant at runtime.
While removing GPU node and CPU nodes also the watchdog node
in the same Module Domain is removed.
A similar approach is implemented for example on i.MX8 and STM32MP1 SoC.

ft_system_setup cannot be enabled on SoC without msmc sram otherwise
fdt_fixup_msmc_ram function fails causing system reset.
Fix by moving fdt_fixup_msmc_ram to common_fdt.c file and creating
SoC (AM654, J721E and J721S2) specific files for fdt fixups.
This change was verified to not change anything on any existing board

For once this adds USB support for two SoCs: the H616 and the F1C100s
series. The rest is support for LPDDR3 DRAM chips on H616 boards.
Gitlab CI passed, and I booted that briefly on an H616 and an F1C200s
board. I don't have an H616 board with LPDDR3 DRAM, but reportedly that
works for Mikhail, and doesn't regress on my DDR3 boards.

The commit a4180c3696 ("arm64: zynqmp: Add mode-pin GPIO controller DT
node") added usb phy reset over bootmode pins by default on usb0 only.
zcu100 is using usb0 as peripheral and usb1 as host. Unfortunately reset
line is shared for both usb ulpi phys but usb_rst_b is connected to usb5744
hub which is used only in host mode. Especially this chip requires reset to
operate properly that's why better assign gpio reset to usb1 instead of
usb0.
Without this change usb start crashed when runs.

Increase reset assert time for TI SGMII PHY on KR260 CC starting
6.1 kernel. This PHY does not come out of reset with the existing
100us pulse width as per testing on multiple carrier cards. The reset
is driven via a PCA9570 I2C expander. The expander driver was updated
to an upstream version in 6.1 where gpio_chip _set was optimized.
Delays in earlier kernels may have masked this issue. This is a safe
workaround value for assert pulse width before the discussions are
resolved with TI.
