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>
2017-08-16env: Rename getenv/_f() to env_get()Simon Glass
We are now using an env_ prefix for environment functions. Rename these two functions for consistency. Also add function comments in common.h. Quite a few places use getenv() in a condition context, provoking a warning from checkpatch. These are fixed up in this patch also.

2017-07-22km/ivm: allow to set locally administred MAC addressesHolger Brunck
It is possible to flag MAC addresses as locally administred. In this case they don't need to be unique. This is only allowed for interfaces which have no connection to the outside. For the TEGR1 board we use this feature. Cc: Heiko Schocher <hs@denx.de> Signed-off-by: Holger Brunck <holger.brunck@keymile.com>
2017-07-22km/ivm: always set ethaddr after reading IVMHolger Brunck

2015-02-16KM/IVM: split the IVM reading and parsing in 2 partsValentin Longchamp
This allows to first read the IVM content (earlier in the boot sequence) and define the ethaddr env variable thanks to the ivm_read_eepromi(). Later, the IVM content can be parsed and used to define some hush variables, when the hush subsystem is available thanks to ivm_analyze_eeprom(). To avoid the HW read to happen twice, the buffer passed to ivm_read_eeprom() has to be reused by ivm_analyze_eeprom (and thus allocated before calling ivm_read_eeprom()).

2014-11-07cppcheck cleanup: fix nullPointer errorsWolfgang Denk

2013-10-24KM: add CONFIG_KM_COMMON_ETH_INIT for km common eth initValentin Longchamp
This must be defined by a board support file that want to use the keymile common.c board_eth_init function that requires ethernet_present to be defined. Currently all the km architectures use it but the kmp204x architecture later supported in this series does use another board_eth_init function and thus does not define it.

kmvect1 has a UEC2 connection to the piggy board and a UEC0 connection to the switch MV88E6122. This switch has a connection to a frontport ethernet interface. The ethernet port used for network booting is automatically selected by u-boot. If a Piggy is plugged, the Piggy port is selected (UEC2, eth1). If the Piggy isn't present, the Frontport is selected (UEC0, eth0). The switch reset is connected to a GPIO on the PRIO3 board FPGA (GPIO28) and released at startup.

2012-09-03km/ivm: fix string len check to support 7 char board namesValentin Longchamp
The fanless boards now have a 7-digit (XXXXX-F) board name. This triggers a border condition when reading this string in the IVM although this string is smaller than the currenly read string size, but only by 1 character.

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.
