2020-05-01net: smc911x: Drop weak alias from 32bit accessorsMarek Vasut
These accessors are not overridden by any board, and even if they were, this is something which should be handled via DM now, so remove the weak alias option. Moreover, drop the inline keyword, as the compiler can decide better.

2020-05-01net: smc911x: Inline all functions from header fileMarek Vasut
Inline all the functions from the header file, as they are not used outside of the driver or the standalone EEPROM example. Note that this does introduce considerable amount of duplication in the standalone EEPROM example, however that one has to be rewritten anyway, roughly such that the SMC911x driver would expose DM EEPROM interface and the standalone example would use that.

2020-05-01net: rtl8139: Fill in SPDX tagMarek Vasut
The rtl8139 driver is derived from Etherboot driver, which is in turn derived from Linux 8139too driver added in Linux 2.2.18pre14. An undocumented change in Linux 2.4.10.2 added a new field to the driver, MODULE_LICENSE("GPL"); . According to current Linux kernel licensing rules, Documentation/process/license-rules.rst, quote: "GPL" Module is licensed under GPL version 2. This does not express any distinction between GPL-2.0-only or GPL-2.0-or-later. The exact license information can only be determined via the license information in the corresponding source files. And since the code does not contain any "future" clause, the tag is therefore GPL-2.0 only. Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com> Cc: Joe Hershberger <joe.hershberger@ni.com>

2020-05-01net: dwc_eth_qos: Prevent DMA from writing updated RX DMA descriptorMarek Vasut
The DMA may attempt to write a DMA descriptor in the ring while it is being updated. By writing the DMA descriptor buffer address to 0, it is assured the DMA will not use such a buffer and the buffer can be updated without any interference.

2020-05-01net: dwc_eth_qos: Invalidate RX packet DMA bufferMarek Vasut
This patch prevents an issue where the RX packet might have been accessed by the CPU, which now has cached data from the packet in the caches and possibly various write buffers, and these data may be evicted from the caches into the DRAM while the buffer is also written by the DMA. By invalidating the buffer after the CPU accessed it and before the DMA populates the buffer, it is assured that the buffer will not be corrupted.

2020-05-01net: dwc_eth_qos: Invalidate RX descriptor before readingMarek Vasut
The current code polls the RX desciptor ring for new packets by reading the RX descriptor status. This works by accident, as the RX descriptors are often in non-cacheable memory. However, the driver does support use of RX descriptors in cacheable memory. This patch adds a missing RX descriptor invalidation, which assures the CPU will read a fresh copy of the RX descriptor instead of a cached one.

2020-05-01net: dwc_eth_qos: Flush the RX descriptors on initMarek Vasut

2020-05-01net: dwc_eth_qos: Correctly wrap around TX descriptor tail pointerMarek Vasut
This code programs the next descriptor in the TX descriptor ring into the hardware as the last valid TX descriptor. The problem is that if the currenty descriptor is the last one in the array, the code will not wrap around correctly and use TX descriptor 0 again, but instead will use TX descriptor at address right past the TX descriptor ring, which is the first descriptor in the RX ring. Fix this by adding the necessary wrap-around.

2020-05-01net: dwc_eth_qos: Fully rewrite RX descriptor field 3Marek Vasut
The RX descriptor field 3 should contain only OWN and BUF1V bits before being used for receiving data by the DMA engine. However, right now, if the descriptor was already used for receiving data and is being cleared, the field 3 is only modified and the aforementioned two bits are ORRed into the field. This could lead to a residual dirty bits being left in the field 3 from previous transfer, and it generally does. Fully set the field 3 instead to clear those residual dirty bits.
