Hello,
I've tried the u-boot 2020.10-rc2 and it's seem i've got some errors:
U-Boot 2020.10-rc2-00204-gc84341f5ac (Aug 24 2020 - 09:49:25 +0200)

According to [0] the board use a winbond W25Q128BVFIG but on the board
it's seem to usea spansion FL128SAIF00.
I've checked if FL128SAIF00 is registered on drivers/mtd/spi/spi-nor-ids.c:
({ INFO6("s25fl128s", 0x012018, 0x4d0180, 64 * 1024, 256,
SPI_NOR_DUAL_READ | SPI_NOR_QUAD_READ | USE_CLSR) },)
I've checked if flash manufacturer was enabled on
configs/xilinx_zynq_virt_defconfig:
CONFIG_SPI_FLASH_SPANSION=y
I checked on [1] to see if the pinout is broken but not.
I dont know how to correct this problem.
For the ethernet it's seem CONFIG_PHY_MICREL_KSZ90X1=y and
CONFIG_PHY_MICREL=y was not on configs/xilinx_zynq_virt_defconfig
But adding it doesn't resolve it:
ZYNQ GEM: e000b000, mdio bus e000b000, phyaddr 0, interface rgmii-id
Could not get PHY for eth0: addr 0
No ethernet found.
I dont (again) know how to correct this problem.
Can you help me ?
