* vboot: cgpt: Treat drive_path as the GPT storageNam T. Nguyen2014-11-141-1/+2
| | | | | | | | | | | | | | | | | | | | | | Previously, "cgpt" called out to "flashrom" directly to read and write NOR area. This CL removes that dependency and always treats "drive_path" as the storage of GPT structs. This makes it consistent that whatever device that cgpt reads from or writes to is always the device that stores GPT structs. We only need to pass in the size of the drive that contains the partitions, but we do not need to access to that drive. More information is in the bug.

* Apply consistent naming scheme for hostlib functions.Bill Richardson2013-03-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The chromeos-installer uses several functions from the vboot_reference userspace library, but the names of those functions are inconsistent: IsZero MapFile VbGetSystemPropertyString cgpt_add cgpt_boot cgpt_create cgpt_get_boot_partition_number cgpt_get_num_non_empty_partitions cgpt_get_partition_details cgpt_prioritize cgpt_set_attributes find_kernel_config The Google C++ style guide says types and functions should use CamelCase, while variables use lower_case_with_underscores. Kernel style (which vboot_reference tries to be more-or-less compatible with) uses lower_case_with_underscores for everything, but that really only has to apply to firmware stuff. For userspace, we can use the Google style. BUG=chromium:221544 BRANCH=none TEST=buildbot CQ-DEPEND=CL:46045 Renaming/cleanup only; no functional changes.

* Implementation of CgptManager C++ library and unit tests.Jay Srinivasan2012-02-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | CgptManager exposes the cgpt commands via a C++ library so that the post-installer for 32- to 64-bit upgrade can link directly against a library and thus avoid any shell dependency. The default make target will not build libcgpt-cc.a since it requires some dependencies that are available only in chroot. A separate follow-up checkin to the vboot_reference ebuild will enable emerging the libcgpt-cc.a by default. BUG=chromium-os:25374 TEST=Tested with the new unit tests for CgptManager, ran existing cgpt unit tests, as well as running the cgpt commands manually. Built on both amd64 and x86. Tested that vboot_reference is also buildable outside of chroot. Tested that vboot_reference-firmware and vboot_reference-tests also build fine with these changes.

* Refactor of cgpt tool for 32->64 autoupdate work.release-R18-1660.BJay Srinivasan2012-01-301-0/+217
This check-in splits the cgpt into two layers. The top layer (cmd_* files) does the command-line parsing and the bottom layer (cgpt_* files) does the actual cgpt work. This is done so that the bottom layer can be reused for the monolithic C++ post-installer code that will be done in subsequent checkins. BUG=chromium-os:25374 TEST=Tested with existing cgpt unit tests as well as running the cgpt commands manually.
