This adds a first support of the FPGA download for a PCIe FPGA based on the BOCO2 CPLD. This takes place in 3 steps, all done accessing the SPICTRL reg of the BOCO2: 1) start the FPGA config with an access to the FPGA_PROG bit 2) later in the boot sequence, wait for the FPGA_DONE bit to toggle to 1 for the end of the FPGA configuration (with a timeout) 3) reset the FPGA 4) finally remove the access to its config EEPROM from the FPGA so that the CPU can update the FPGA configuration when the kernel is running The boards with a PCIe FPGA but without BOCO2 still are supported. The config option name is CONFIG_KM_FPGA_CONFIG Signed-off-by: Valentin Longchamp <valentin.longchamp@keymile.com> Signed-off-by: Holger Brunck <holger.brunck@keymile.com> cc: Gerlando Falauto <gerlando.falauto@keymile.com> cc: Prafulla Wadaskar <prafulla@marvell.com>
