2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
2016-09-23treewide: replace #include <asm/errno.h> with <linux/errno.h>Masahiro Yamada
Now, arch/${ARCH}/include/asm/errno.h and include/linux/errno.h have the same content. (both just wrap <asm-generic/errno.h>) Replace all include directives for <asm/errno.h> with <linux/errno.h>.

2014-02-13arm/km: introduce kmsugp1 targetGerlando Falauto
KMSUGP1 is from a u-boot perspective (almost) identical to KMNUSA. The only difference is that the PCIe reset is connected to Kirkwood pin MPP7_PEX_RST_OUTn, we use a dedicated config flag KM_PCIE_RESET_MPP7. Such pin should theoretically be handled by the PCIe subsystem automatically, but this turned out not to be the case. So simply configure this PIN as a GPIO and issue a pulse manually.

2012-07-07arm/km: support the 2 PCIe fpga resetsValentin Longchamp
The PCIe FPGAs now have to support 2 resets: one for the non traffic affecting part (PCIe) and one for the traffic affecting part. When the FPGA is not reconfigured, we only reset the PCIe part. Signed-off-by: Valentin Longchamp <valentin.longchamp@keymile.com>
2012-07-07arm/km: skip FPGA config when already configuredValentin Longchamp
In order to be able to perform board resets without interrupting the traffic, the configuration of an already properly configured FPGA is skipped. This is because some PCIe FPGAs embed some other function that must continue to work over reset. It is then the responsibility of the application to trigger a reconfiguration when needed. This is done by lowering the FPGA_INIT_B pin for delaying the configuration to u-boot @ next reboot, and then lower the FPGA_PROGRAM_B signal.

2012-07-07arm/km: enable BOCO2 FPGA download supportValentin Longchamp
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>
