net: macb: let miiphy_read/_write pass arbitrary addresses

2019-12-09T15:47:42+00:00

This allows passing arbitrary addresses through macb_miiphy_read and
macb_miiphy_write, therefore enabling the mii command to access
all mdio bus devices instead of only the defined phy.

net: macb: explicitly pass phy_adr to mdio read and write

2019-12-09T15:47:42+00:00

To support accessing arbitrary addresses the mii/mdio bus it is
necessary that the macb_mdio_read and macb_mdio_write functions
do not implicitly use the address of the connected phy.

The function signature is extended according to the Linux kernel
equivalent.

net: macb: Fix rx buffer cache handling

2019-09-04T16:37:19+00:00

With commit c6d07bf440bc ("net/macb: increase RX buffer size for GEM")
ethernet support does not work any more with d-cache enabled on the
AT91SAM. The reason is, that MACB_RX_BUFFER_SIZE was changed from 4096
to 128 but this change was not refected in the rx_buffer flush and
invalidate functions, as these also use this macro.

This patch now fixes this by calculating the rx buffer size correctly
again in those functions. With this change, ethernet works again
reliably on my AT91SAM board.

net: macb: Fix check for little-endian system in gmac_configure_dma()

2019-07-25T18:13:31+00:00

Instead of depending on CONFIG_SYS_LITTLE_ENDIAN, we check at runtime
whether underlying system is little-endian or big-endian. This way
we are not dependent on any U-Boot specific OR compiler specific macro
to check system endianness.

net: macb: Extend MACB driver for SiFive Unleashed board

2019-07-25T18:13:31+00:00

The SiFive MACB ethernet has a custom TX_CLK_SEL register to select
different TX clock for 1000mbps vs 10/100mbps.

This patch adds SiFive MACB compatible string and extends the MACB
ethernet driver to change TX clock using TX_CLK_SEL register for
SiFive MACB.

net/macb: increase RX buffer size for GEM

2019-07-25T18:13:30+00:00

Macb Ethernet controller requires a RX buffer of 128 bytes. It is
highly sub-optimal for Gigabit-capable GEM that is able to use
a bigger DMA buffer. Change this constant and associated macros
with data stored in the private structure.
RX DMA buffer size has to be multiple of 64 bytes as indicated in
DMA Configuration Register specification.
