[PATCH v2 00/14] Tools updates for Labgrid

This series includes patches to update buildman to support Labgrid better and some minor binman fixes and improvements.
Changes in v2: - Move the binman assume-size feature into this series
Simon Glass (14): binman: efi: Correct entry docs binman: Regenerate nxp docs binman: ti: Regenerate entry docs binman: Update the entrydocs header binman: Support an assumed size for missing binaries binman: Make Intel ME default to position 0x1000 x86: Set up some assumed sizes for binary blobs buildman: Make mrproper an argument to _reconfigure() buildman: Make mrproper an argument to _config_and_build() buildman: Make mrproper an argument to run_commit() buildman: Avoid rebuilding when --mrproper is used buildman: Add a flag to force mrproper on failure buildman: Retry the build for current source buildman: Add a way to limit the number of buildmans

Binman has a the useful feature of handling missing external blobs gracefully, including allowing them to be missing, deciding whether the resulting image is functional or not and faking blobs when this is necessary for particular tools (e.g. mkimage).
This feature is widely used in CI. One drawback is that if U-Boot grows too large to fit along with the required blobs, then this is not discovered until someone does a 'real' build which includes the blobs.
Add a 'assume-size' property to entries to allow Binman to reserve a given size for missing external blobs.

This cannot ever go at offset 0 since the descriptor is there. Use a better offset for the ME, as used by link and coral, for example.
This matters when we start using assumed sizes for missing blobs.

This cannot ever go at offset 0 since the descriptor is there. Use a better offset for the ME, as used by link and coral, for example.

Applied to u-boot-dm/next, thanks!

Buildman uses all available CPUs by default, so running more than one or two concurrent processes is not normally useful.
However in some CI cases we want to be able to run several jobs at once to save time. For example, in a lab situation we may want to run a test on 20 boards at a time, since only the build step actually takes much CPU.
Add an option which allows such a limit. When buildman starts up, it waits until the number of running processes goes below the limit, then claims a spot in the list. The list is maintained with a temporary file.
Note that the temp file is user-specific, since it is hard to create a locked temporary file which can be accessed by any user. In most cases, only one user is running jobs on a machine, so this should not matter.

Buildman uses all available CPUs by default, so running more than one or two concurrent processes is not normally useful.
However in some CI cases we want to be able to run several jobs at once to save time. For example, in a lab situation we may want to run a test on 20 boards at a time, since only the build step actually takes much CPU.
Add an option which allows such a limit. When buildman starts up, it waits until the number of running processes goes below the limit, then claims a spot in the list. The list is maintained with a temporary file.
Note that the temp file is user-specific, since it is hard to create a locked temporary file which can be accessed by any user. In most cases, only one user is running jobs on a machine, so this should not matter.
