2018-10-08Move compiler.h to commonlibNico Huber
Its spreading copies got out of sync. And as it is not a standard header but used in commonlib code, it belongs into commonlib. While we are at it, always include it via GCC's `-include` switch. Some Windows and BSD quirk handling went into the util copies. We always guard from redefinitions now to prevent further issues.

2018-04-24compiler.h: add __weak macroAaron Durbin
Instead of writing out '__attribute__((weak))' use a shorter form.

2016-08-19lib/boot_device: add RW boot device constructAaron Durbin
The current boot device usage assumes read-only semantics to the boot device. Any time someone wants to write to the boot device a device-specific API is invoked such as SPI flash. Instead, provide a mechanism to retrieve an object that can be used to perform writes to the boot device. On systems where the implementations are symmetric these devices can be treated one-in-the-same. However, for x86 systems with memory mapped SPI the read-only boot device provides different operations.

2015-10-31tree: drop last paragraph of GPL copyright headerPatrick Georgi
It encourages users from writing to the FSF without giving an address. Linux also prefers to drop that and their checkpatch.pl (that we imported) looks out for that. This is the result of util/scripts/no-fsf-addresses.sh with no further editing.

2015-10-27boot_device: add call to boot_device_init()Aaron Durbin
In the program loading paths using vboot it's possible that the boot media has not been initiazed for that stage. Therefore, provide this call such that it's guaranteed to be called at least once. BUG=chrome-os-partner:44827 BRANCH=None TEST=Built and booted glados.

2015-05-26coreboot: introduce boot_deviceAaron Durbin
The boot_device is a region_device that represents the device from which coreboot retrieves and boots its stages. The existing cbfs implementations use the boot_device as the intermediary for accessing the CBFS region. Also, there's currently only support for a read-only view of the boot_device. i.e. one cannot write to the boot_device using this view. However, a writable boot_device could be added in the future.
