QEMU ppce500 machine can dynamically instantiate an eTSEC device if "-device eTSEC" is given to QEMU.
This series updates the fixed-link ethernet PHY driver as well as the Freescale eTSEC driver to support the QEMU ppce500 board.
3 patches related to fixed phy in v1 are dropped in v2 as the changes were done by Vladimir's fixed phy & Sandbox DSA series [1]. Vladimir's series is now included in v2 to avoid dependencies.
This cover letter is cc'ed to QEMU mailing list for a heads-up. A future patch will be sent to QEMU mailing list to bring its in-tree U-Boot source codes up-to-date.
Azure results: PASS https://dev.azure.com/bmeng/GitHub/_build/results?buildId=343&view=resul...
This series is avaiable at u-boot-x86/eTSEC for testing.

Changes in v4: - describe "ranges" is required fo the alternate description - make platform_bus_map_region() return void
Changes in v3: - mention that U-Boot deliberately ignores the 'phy_id' and unconditionally uses PHY_FIXED_ID - update the code logic to prefer the new binding if both new and old bindings exist - sort variable definitions by line length - reuse the sandbox dsa nodes for the fixed-link testing - new patch: net: tsec: Use map_physmem() directly instead of dev_remap_addr() - add "ranges" in the alternate example - keep the variable definitions sorted - invert the strncmp logic to reduce the indentation level - add a comment to mention only the first "queue-group" is used - call the same map_physmem() in the common code path - extract platform bus virtual memory mapping codes to a new routine - add a "break" in case multiple "qemu,platform" nodes exist
Changes in v2: - move device tree parsing from xilinxgmiitorgmii_probe() to xilinxgmiitorgmii_config() and use OF APIs - new patch: split from 20210216224804.3355044-4-olteanv@gmail.com - include <asm/global_data.h> - use a Kconfig option CONFIG_SIMPLE_BUS_CORRECT_RANGE to control the new behavior for boards that want this - default y if SANDBOX for CONFIG_SIMPLE_BUS_CORRECT_RANGE - turn on CONFIG_SIMPLE_BUS_CORRECT_RANGE in qemu-ppce500_defconfig
