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

2019-07-25T18:13:31Z

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

2019-07-25T18:13:31Z

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

2019-07-25T18:13:30Z

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.

net: macb: apply sane DMA configuration

2019-07-25T18:13:30Z

DMA configuration was heavily dependent on the HW defaults, add function to properly set the required fields, including the new dma_burst_length. Signed-off-by: Ramon Fried Reviewed-by: Anup Patel Tested-by: Anup Patel Acked-by: Joe Hershberger

net: macb: add dma_burst_length config

2019-07-25T18:13:30Z

GEM support higher DMA burst writes/reads than the default (4). add configuration structure with dma burst length so it could be applied later to DMA configuration. Signed-off-by: Ramon Fried Reviewed-by: Anup Patel Tested-by: Anup Patel Acked-by: Joe Hershberger

net: macb: sync header definitions as taken from Linux

2019-07-25T18:13:30Z

Few registers and bits were added by Cadence and they were not updated in the headers. Take the latest definitions as defined in Linux header (5.1) that also includes some comments about existing registers. One register was improperly named (UR), fix that.
