This adds DDR training. The training has a small chance of failing,
and then the training is restarted.
DDR training cannot be done meaningfully while the software is
in DDR. If the system is intended to run from eNVM, like a
bootloader, the linker script should be tuned to utilize the envm
region as follows:
envm (rx) : ORIGIN = 0x20220100, LENGTH = 128K - 256
l2lim (rwx) : ORIGIN = 0x08000000, LENGTH = 1024k
256 bytes are reserved for the system; The fixed block may be
installed from the 'hart-software-services' -repository:
https://github.com/polarfire-soc/hart-software-services.git
For example, the 256-byte image: hss-envm-wrapper-bm1-dummySbic.bin
may be prepended on the nuttx bootloader image in the following
manner:
cat hss-envm-wrapper-bm1-dummySbic.bin > nuttx_bootloader.bin
cat nuttx.bin >> nuttx_bootloader.bin
riscv64-unknown-elf-objcopy -I binary -O ihex --change-section-lma
*+0x20220000 nuttx_bootloader.bin flashable_image.hex
This provides an image 'flashable_image.hex' that may be flashed on
the eNVM region via Microsemi Libero tool.

Since the tests were removed from the drivers, there is no need for
these defconfigs anymore.

-march=rv64gc -mabi=lp64 does not resolve lib paths for
riscv64-unknown-elf-gcc resulting in lib not found errors.
Changing it to -march=rv64imafc -mabi=lp64f that is the default
used in Sipeed repositories.

This commit moves the Wi-Fi initialization to
Wi-Fi specific file and to spiflash initialization.
It also reserves one partition for Wi-Fi use and for general use,
and makes it possible to me mounted by several FS.
several configs are used for testing and need the BSD components

By default the components with BSD license should be disabled
NOTE:
the BLUETOOTH components was enabled in a non bluetooth config

Add a driver for CorePWM block, which can be instantiated on PolarFire SOC FPGA
This supports 2 CorePWM blocks on the FPGA. One CorePWM block provides 8 PWM output signals
1. Added check for repeated connection wifi operations.
2. Invoke the carrier on/off operation in the wrong place.
3. The RTC initialization time is incorrect.
4. Reserve 32K I-Cache space in the linker script.
5. Increase the size of the wifi firmware receiving buffer.
