[PATCH v2 00/21] ppc: qemu: Add eTSEC support

[Bin Meng <bmeng.cn@gmail.com>]

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, and updated as needed.

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.

This series is avaiable at u-boot-x86/eTSEC for testing.

[1] https://patchwork.ozlabs.org/project/uboot/patch/20210216224804.3355044-2-olteanv at gmail.com/

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
