| Speed up bit reversal by using hardware bit reversal Add extra code to handle less than 4byte remnants, if any Signed-off-by: Joshua Clayton <stillcompiling@gmail.com> Signed-off-by: Alan Tull <atull@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> | |||
| 2017-07-17 | fpga manager: Add altera-ps-spi driver for Altera FPGAs | Joshua Clayton | |
| altera-ps-spi loads FPGA firmware over SPI, using the "passive serial" interface on Altera Arria 10, Cyclone V or Stratix V FPGAs. This is one of the simpler ways to set up an FPGA at runtime. The signal interface is close to unidirectional SPI with lsb first.
