This patch adds the necessary lowlevel init code, to enable SMP Linux
booting. This code will be used with the platform specific Octeon Linux
boot command "bootoctlinux", which starts a configurable number of cores
into Linux.

Additionally some erratas and lowlevel register initializations are
copied from the original Cavium / Marvell U-Boot source code, enabling
booting into the Linux kernel.

Octeon uses mapped addresses for virtual and physical memory. It's not
that easy to calculate the resulting addresses here. So let's remove
this BUG_ON() completely, as it's not really helpful.

Please also note, that BUG_ON() is not recommended any more in the Linux
kernel.

Pull request for UEFI sub-system for efi-2021-01-rc1

The following bugs in the UEFI system are resolved:

* illegal free in EFI_LOAD_FILE2_PROTOCOL implementation
* incorrect documentation of EFI_LOAD_FILE2_PROTOCOL implementation
* output of CRC32 as decimal instead hexadecimal in unit test
* use EfiReservedMemoryType for no-map reserved memory
* avoid unnecessary resets in UEFI unit tests
* call EFI bootmgr even without having /EFI/boot

- generate unique mac address from SoC serial on S400 board
- Add USB support for GXL and AXG SoCs
- Update Gadget code to use the new GXL and AXG USB glue driver
- Add a VIM3 board support to add dynamic PCIe enable in OS DT
- Fix AXG pinmux with requesting GPIOs
- Add missing GPIOA_18 for AXG pinctrl
- Add Amlogic PWM driver

The device tree may contain a /reserved-memory node. The no-map property
of the sub-nodes signals if the memory may be accessed by the UEFI payload
or not.

In the EBBR specification (https://github.com/arm-software/ebbr) the
modeling of the reserved memory has been clarified.

If a reserved memory node in the device tree has the no-map property map,
create a EfiReservedMemoryType memory map entry else use
EfiBootServicesData.

Currently, the EFI bootmgr is only called if there is a EFI binary
inside the path for removable media is found, i.e. /EFI/boot/. This
doesn't make sense. It is the duty of the bootmgr to find out the
path and name of the EFI binary to boot. It should be called even
if there is no /EFI/boot directory.

Thus, call the bootmgr before we try to boot the EFI binary inside
the removable media path.

Also remove the ${fdtcontroladdr} parameter because the fallback is
handled in cmd/bootefi.c and that already takes care of correct settings
if the board has ACPI and thus no device tree at all.

This adds the driver for the PWM controller found in the Amlogic SoCs.

This PWM is only a set of Gates, Dividers and Counters:
PWM output is achieved by calculating a clock that permits calculating
two periods (low and high). The counter then has to be set to switch after
N cycles for the first half period.
The hardware has no "polarity" setting. This driver reverses the period
cycles (the low length is inverted with the high length) for
PWM_POLARITY_INVERSED.

Disabling the PWM stops the output immediately (without waiting for the
current period to complete first).

The VIM3 on-board  MCU can mux the PCIe/USB3.0 shared differential
lines using a FUSB340TMX USB 3.1 SuperSpeed Data Switch between
an USB3.0 Type A connector and a M.2 Key M slot.
The PHY driving these differential lines is shared between
the USB3.0 controller and the PCIe Controller, thus only
a single controller can use it.
