This patch adds glue code required for enabling the designware

ethernet is not working at my end, is it working at your end.
Just tested it again with a clean clone of u-boot master with my patchset
and stm32f746-disco_defconfig. It works for me: dhcp, ping and dns to
local and internet addresses.

Changes in v3:
- Add Acked-by tag to 'add designware mac glue code for stm32'
Changes in v2:
- Replaced bit shifts and masks with BIT() and GENMASK() macro
- Moved STM32_SYSCFG_BASE into stm32.h header

adding compatible for the soc in the peripheral driver ?
why not to use the existing one in the stm32 dts file. I see others (allwinner,
altr ) have also done the same which is unnecesary & not as per binding.
please replace compatible string with one mentioned in binding doc(something like
"snps, dwmac") in the driver as well the dts of stm32, allwinner, altr etc.
Cheers,
Vikas
That makes sense. I followed the others. I'll change it to the common one
in both dts and in the driver.
Regards,
Michael
