* include: Allow git kernel branch selectionJohn Crispin2014-06-021-0/+4
| | | | | | | | | This allows the selection of a specific branch in the menuconfig when using a kernel downloaded from GIT. Signed-off-by: Mathieu Olivari <mathieu@qca.qualcomm.com> git-svn-id: svn://svn.openwrt.org/openwrt/trunk@40946 3c298f89-4303-0410-b956-a3cf2f4a3e73
* include: Clean-up kernel git command options managementJohn Crispin2014-06-021-1/+7
| | | | | | | | | | | | | | | | | The way git options are managed in kernel-defaults.mk makes additions difficult. If requires different code path for each option; it's ok so far as we handle only one option, but if we want to make the git clone mechanism more flexible, more option will be required, which will become tedious. So; we'll move the GIT options into a variable, that may or may not be set depending on the configuration, and we'll pass this variable to the git command.

* config: Remove KERNEL_GIT_LOCAL_REPOSITORY optionJohn Crispin2014-06-021-8/+2
| | | | | | | | | | | | | | | | | | | | The GIT_LOCAL_REPOSITORY option adds the --reference argument to the git clone kernel command line, if KERNEL_GIT_CLONE_URI is set. This option is intended to speed-up the repo creation by using local objets rather than downloading it. However, a local repo can be cloned much faster by setting GIT_LOCAL_REPOSITORY directly to the local tree. In that case, git clone will bypass the normal "git aware" transport mechanism and clone the repository by copying and hardlinking objects rather than downloading it, resulting in a significant speed increase. That makes the GIT_LOCAL_REPOSITORY option pretty useless so we'll just remove it and recommand the usage of KERNEL_GIT_CLONE_URI directly.

* sparse: add as a new package selectable from the configJohn Crispin2014-04-121-0/+4
| | | | | | | | | | | | | This change does multiple things, all related to enable sparse usage as a static analysis tool selectable from the OpenWrt configuration: *add a KERNEL_SPARSE option in the config to add sparse to the kernel build (through the C=1 option usage) *add sparse as a new host tools. It will get selected automatically when the above option will be enabled Signed-off-by: Mathieu Olivari <mathieu@qca.qualcomm.com> git-svn-id: svn://svn.openwrt.org/openwrt/trunk@40490 3c298f89-4303-0410-b956-a3cf2f4a3e73
