hw/net: Add NPCMXXX GMAC device
This patch implements the basic registers of GMAC device and sets registers for networking functionalities. Squashed IRQ Implementation patch into this one for compliation. Tested: The following message shows up with the change: Broadcom BCM54612E stmmac-0:00: attached PHY driver [Broadcom BCM54612E] (mii_bus:phy_addr=stmmac-0:00, irq=POLL) stmmaceth f0802000.eth eth0: Link is Up - 1Gbps/Full - flow control rx/tx Change-Id: If71c6d486b95edcccba109ba454870714d7e0940 Signed-off-by: Hao Wu <wuhaotsh@google.com> Signed-off-by: Nabih Estefan Diaz <nabihestefan@google.com> Reviewed-by: Tyrone Ting <kfting@nuvoton.com> Message-id: 20240131002800.989285-2-nabihestefan@google.com Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
