2016-01-28misc: Add simple driver to enable the legacy UART on Winbond Super IO chipsStefan Roese
On most x86 boards, the legacy serial ports (io address 0x3f8/0x2f8) are provided by a superio chip connected to the LPC bus. We must program the superio chip so that serial ports are available for us.

2016-01-27spi: fsl_qspi: Fix qspi_op_rdsr memcpy issueGong Qianyu
In current driver, we always copy 4 bytes to the dest memory. Actually the dest memory may be shorter than 4 bytes. Add an argument to indicate the dest memory length. Avoid writing memory outside of the bounds. Signed-off-by: Gong Qianyu <[email protected]> Reviewed-by: York Sun <[email protected]>

2016-01-27net: emaclite: Use indirect access in emaclite_recvMichal Simek
When IP is configured with pong buffers, IP is receiving packets to ping and then to pong buffer and than ping again. The original logic in the driver remains there that when ping buffer is free, pong buffer is checked too and return if both are free. Signed-off-by: Michal Simek <[email protected]>
2016-01-27net: emaclite: Use indirect reg access in sendMichal Simek
The original logic in the driver was exchanging buffers which are used for sending packet and tx_ping and tx_pong buffers were exchanged all the time to ensure that IP has enough time to send the packet out. Based on this "feature" send function was using nextbuffertouse variable to save which buffer should be used. Before this algorithm was called driver checked that there is free buffer available. This checking remains in the driver but driver tries to use tx_ping first if available. If not, tx_pong buffer is used instead. To reach this code the original condition is met that at least one of the buffer should be available. Testing doesn't show any performance drop when this patch is applied.
