From b37f772433ab44d1730423eccf11f287ce61ec5f Mon Sep 17 00:00:00 2001 From: Valentin Longchamp Date: Thu, 5 Jul 2012 05:05:05 +0000 Subject: arm/km: enable BOCO2 FPGA download support 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 Signed-off-by: Holger Brunck cc: Gerlando Falauto cc: Prafulla Wadaskar --- board/keymile/common/common.h | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'board/keymile/common/common.h') diff --git a/board/keymile/common/common.h b/board/keymile/common/common.h index f457aa30c6..aab706e6c9 100644 --- a/board/keymile/common/common.h +++ b/board/keymile/common/common.h @@ -131,6 +131,11 @@ struct bfticu_iomap { int ethernet_present(void); int ivm_read_eeprom(void); +int trigger_fpga_config(void); +int wait_for_fpga_config(void); +int fpga_reset(void); +int toggle_eeprom_spi_bus(void); + int set_km_env(void); int fdt_set_node_and_value(void *blob, char *nodename, -- cgit v1.2.1
