mtk_eth.c contains not only the ethernet GMAC/DMA driver, but also some ethernet switch initialization code. As we may add more switch support in the future, it's better to move them out of mtk_eth.c to avoid increasing the code complexity. Since not all switches are supported for a particular board, Kconfig options are added to allow user to select which switch should be built into u-boot. If multiple switches are selected, auto-detecting can also be enabled. Signed-off-by: Weijie Gao <weijie.gao@mediatek.com>
The wget command currently cannot work correctly with mtk_eth driver. This patch fixed this by increase DMA ring size and invalidate ring data after use. Signed-off-by: Weijie Gao <weijie.gao@mediatek.com>
Enable GDMA cpu bridge only when 10Gb interface is enabled for GMAC other than GMAC0, or when MT7988 internal switch is used. Signed-off-by: Weijie Gao <weijie.gao@mediatek.com>
Not all platforms supports sgmii and/or usxgmii. So we add Kconfig options for these features and enable them only for supported platforms. Signed-off-by: Weijie Gao <weijie.gao@mediatek.com>

MT7629 need extra setting for gmac2 to work. So additional capability is added for mt7629 to handle this case. Signed-off-by: Weijie Gao <weijie.gao@mediatek.com>
Unlike other platforms, mt7622 has only one SGMII and it can be attached to either gmac1 or gmac2. So the register field of the sgmii selection differs from other platforms as newer platforms can control each sgmii individually. This patch adds a new capability for mt7622 to handle this case.

The SYSCFG0 should be SYSCFG1 according to the programming guide. Signed-off-by: Weijie Gao <weijie.gao@mediatek.com>
The register field for SGMII speed selection is a 2-bit field with value 0 for 1Gbps and 1 for 2.5Gbps (2/3 are reserved). So it's necessary to set both bits instead of just setting/clearing only the lower bit. Signed-off-by: Weijie Gao <weijie.gao@mediatek.com>
