Simplify the clock mode from the board.h -files. Also make the
SD clock definable as well.

Some related products, such as Aries m100pfs, don't support eMMC
speeds up to 200MHz. Thus, provide option to select slower clock.
This has only to do with the clocking, no CMD6 is sent to select
high speed modes.

The underlying hardware supports 9 endpoints:
- EP0
- 4x IN EPs
- 4x OUT EPs
Currently the driver assumes every EP number is unique. This limits
the amount of EPs to 1 + 4 = 5. Utilize the EPs in such a manner
that all may be used.
Also fix a few error handling related bugs. Update the composite
driver to match the current situation as well.

rename the UDP_BINDTODEVICE to SO_BINDTODEVICE to follow the linux

It is not really needed; g_hart_stacks is only used during SBI init as
a temporary stack area. We can use the scratch area buffers for this, as
the scratch areas define almost 4K of extra space, which is used for
exception stacks anyway.
After #6400 the prebuilt bootloader may be used for loading the NuttX
images when BUILD_PROTECTED is enabled.

Sync some of the AXI configuration and DDR training parameters with the manufacturer's
defaults.
The TIP_CFG parameter correction helps with DDR training failures on some individual boards
The AXI end address values fix early random crash in power-on boot on some individual boards

Update PLL configuration parameters to match the values provided
by the vendor.
Also remove extra call to mpfs_pll_config() as it's already called
at mpfs_clockconfig().

This provides USB composite (CDC/ACM and Mass Storage) support
for mpfs board. In addition, a number of USB fixes are included:
- Support for Setup Out packets
- Proper support for larger than packet size writes
- Finishing setup packets properly

Linux kernel uses M-mode trap for handling Inter-Hart Communication (IHC).
This patch provides all the required functionalities for this purpose.
Previously, HSS bootloader was required. Now, NuttX is run as the
bootloader providing OpenSBI vendor extensions instead. This setup has
been tested on the following configuration:
- Hart 0 has NuttX in bootloader mode with OpenSBI
- Hart 1 unused
- Hart 2 has NuttX configured at 0xa2000000
- Hart 3 has U-boot / Linux kernel (at 0x80200000)
- Hart 4 has U-boot / Linux kernel (at 0x80200000)
Upon startup, NuttX on hart 0 will initialize SD-card driver, loads
the hart 2 NuttX from the SD-card and loads the U-boot to 0x80200000.
Also the nuttx.sbi -binary is loaded from SD-card into address 0x80000000,
which is also marked as reserved area in the Linux kernel device tree (for
the chuck 0x80000000 - 0x80200000).
Hart 2 NuttX waits until Linux kernel (IHC master) is started. After the
initial handshake, RPMsg / virtIO bus along with the IHC may be used for
proper AMP mode.

This provides an example of Asymmetric Multiprocessing (AMP). The
master from Linux sends pings that this NuttX echoes back. The system
uses RPMsg from OpenAMP.
The Inter-Hart Communication module is present in the vendor's software
stack with the tag "2021.11". The software is present on github at the
polarfire-soc project. The following conditions must be met:
1. FPGA programmed with 2021.11 software
2. HSS (Vendor bootloader) with 2021.11 software
3. U-boot and Linux kernel from 2011.11 software
Currently the IHC works as a slave only on the hart number 4.
On the NuttX side, this patch uses rptun that incorporates rpmsg and
virtio. If it used only rpmsg and virtio, the future maintenance would
likely be much heavier. Using rptun also simplifies many things.
Upon success, the master side from Linux may issue an example test:
root@icicle-kit-es-amp:/opt/microchip/amp/rpmsg-pingpong# ./rpmsg-pingpong
However, the rpmsg-pingpong.c (compiled on target with gcc), may need to
be modified as seen below to match the device id:
- char *rpmsg_dev="virtio0.rpmsg-amp-demo-channel.-1.0";
+ char *rpmsg_dev="virtio0.rpmsg-amp-demo-channel.-1.1024";
This work uses a separate linker script. Due to a bug yet unknown to date,
a small NuttX, when loaded by the vendor HSS bootloader, will cause the
Linux kernel to hang at boot. Thus, the binary size is increased with
a section 'filler_area' whose only purpose is to increase the image size
so that the Linux kernel will boot up.
