[U-Boot] [PATCH v3 0/3] Add Ethernet support for Poplar board

[Shawn Guo]

The series adds Ethernet support for Poplar board.  It firstly creates
a reset driver for HiSilicon platform, then introduces higmacv300
Ethernet driver, and finally enables Ethernet support for Poplar board.

Changes for v3:
 - Add polarity support into reset driver, so that we can drop the
   hacking on gmac reset sequence from higmacv300 driver.
Changes for v2:
 - Rename driver symbol to HIGMACV300_ETH.
 - Remove the use of temp variable 'addr' in higmac_recv().
 - Simplify the return of function higmac_ofdata_to_platdata() and
   higmac_probe().
 - Combine delaration and initialization for phyintf in function
   higmac_ofdata_to_platdata().
 - Eliminate the MDIO read/write macros.
 - Use wait_for_bit_le32() for MDIO command completion polling.
 - Set up RX packet buffers in RX_FQ descriptor at initialization time,
   so that we do not need to allocate/free packet buffers repeatedly.
 - Inform GMAC that the RX descriptor is no longer in use in function
   higmac_free_pkt().
 - Define BITS_DESC_ENA instead of using magic number 0xf.
