Z-Turn board support on U-Boot 2020.10-rc2, got some errors.

[Alexandre GRIVEAUX]

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)

CPU:   Zynq 7z020

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 ?
