Neil Armstrong 7ccc73773f ARM: mach-meson: use new DWC3 glue for GXL & GXM

Neil Armstrong 46eddbc58f usb: dwc3: add Amlogic GXL & GXL DWC3 Glue
The USB support was initialy done with a set of PHYs and dwc3-of-simple
because the architecture of the USB complex was not understood correctly
at the time (and proper documentation was missing...).

But with the G12A family, the USB complex was correctly understood and
implemented correctly.

This adds a proper driver for the glue, based on the G12A one, but with
enough changes to require a different driver in U-Boot.

Soeren MochandTom Rini 0f3e2942c9 board: tbs2910: Use recommended distroboot addresses
According to doc/README.distro fdt_addr must not be set when DTB is not
available from hardware. So remove this entry.

Use address 32MB above the start of DRAM for kernel_addr_r. This way
we likely can avoid the self-relocation of the compressed kernel image
before it decompresses to offset 0x8000 from start of DRAM.

Use address 128MB above the start of DRAM for fdt_addr_r, since this is
the maximum location for the end of the kernel. So we avoid overwriting
the DTB.

Use 512k above that for ramdisk_addr_r. This should be enough for the
DTB, rest of DRAM can be used for initrd.

Place boot script / extlinux.conf at offset 0 / 1MB from start of DRAM.
This space is available for processing in U-Boot.

Heinrich Schuchardt c48e9f310b riscv: restore global data pointer in trap handler
The gp register is used to store U-Boot's global data pointer. We should
not assume that an UEFI application leaves the gp register unchanged as
the UEFI specifications does not define who is the owner of the gp and tp
registers.

So the following sequence should be followed in the trap handler:

* save the caller's gp register
* restore the global data pointer
* serve interrupts or print crash dump and reset
* restore the caller's gp register

Neil Armstrong 02d249f99e rng: meson: make core clock optional
This fixes HWRNG support on Amlogic GXL, GXM, G12A, G12B & SM1
based boards dues to the lack of the core clock in the device tree.

It was reported breaking EFI boot in the Linux EFI stub, because the
EFI_RNG_PROTOCOL didn't check for the RNG device presence before
installing itself.

The Linux amlogic,meson-rng.yaml doesn't mandate the core clock,
this the clock should be ignores if not present.

Nevertheless, the clock should be present and this should be fixed
on the Linux meson-gxl.dtsi & meson-g12-common.dtsi then synced
with U-Boot.

The change has been tested on a Khadas VIM3, which uses the common
meson-g12-common.dtsi like the Odroid-C4 & Odroid-N2 in Scott's
report, along with the RNG cmd.

Pali RohárandStefan Roese 5f50b88ab6 arm64: a37xx: pci: Disable link training when unloading driver
As required by PCI Express spec a delay for at least 100ms after
de-asserting PERST# signal is needed before link training is enabled.

Linux kernels prior to 5.8 version do not automatically disable link
training before de-asserting PERST# signal, therefore this requirement is
not fulfilled.

Above requirement is needed for proper detection of some Compex PCIe WiFi
cards. Otherwise Linux kernel cannot detect it.

To allow using those PCIe cards with older Linux kernel versions booted by
U-Boot compiled with U-Boot a37xx pci driver, disable link training in
U-Boot when unloading this pci driver.

Thanks to DM_FLAG_OS_PREPARE flag, U-Boot automatically unload this driver
when booting Linux kernel.
