This series of patches base on the latest branch/master,and
adds ethernet support for the StarFive JH7110 RISC-V SoC.
The series includes EEPROM, PHY and MAC drivers. The PHY model is
YT8531 (from Motorcomm Inc), and the MAC version is dwmac-5.20
(from Synopsys DesignWare).
The implementation of the phy driver is ported from linux, but it
has been adjusted for the u-boot framework.
EEPROM stores board-related information, such as DDR capacity,
PCB version, MAC address, etc.
The main difference between StarFive VisionFive 2 1.2A and 1.3B is
gmac, but the difference in gmac is not defined in DT, but reads the
PCB version from EEPROM, and then dynamically configures the difference
of gmac according to different PCB versions, which is compatible
with 1.2A and 1.3B versions, which is more user-friendly.
The PHY and MAC driver has been tested on the StarFive VisionFive 2 1.2A
and 1.3B boards and works normally.
For more information and support,you can visit RVspace wiki[1].

v4:
- Reworded the definition of the 'pbuf' variable in visionfive2-i2c-eeprom.c
from a const pointer to const union.
- Added the section (".data") attribute to the 'pbuf' and 'has_been_read' global
variables in visionfive2-i2-eeprom.c.
v3:
- Added EEPROM support.
- Combine the board device tree of 1.2A and 1.3B into one.
- Removed the delay configuration of gmac phy clock from DT.
- Dynamically configure gmac differences of 1.2A and 1.3B to DT according to the PCB version.
- DDR capacity information is read from EEPROM first, if not, it is defined by default in DT.
v2:
- Reworded the phy driver. Added platform private data struct to save the
configuration data read from dts.
- Reworded the MAC driver. Added platform private data struct to save the
configuration data read from dts.
