Stephen Warren [Mon, 11 Apr 2016 16:48:44 +0000 (10:48 -0600)]
buildman: allow more incremental building

One use-case for buildman is to continually run it interactively after
each small step in a large refactoring operation. This gives more
immediate feedback than making a number of commits and then going back and
testing them. For this to work well, buildman needs to be extremely fast.
At present, a couple issues prevent it being as fast as it could be:

1) Each time buildman runs "make %_defconfig", it runs "make mrproper"
first. This throws away all previous build results, requiring a
from-scratch build. Optionally avoiding this would speed up the build, at
the cost of potentially causing or missing some build issues.

2) A build tree is created per thread rather than per board. When a thread
switches between building different boards, this often causes many files
to be rebuilt due to changing config options. Using a separate build tree
for each board would avoid this. This does put more strain on the system's
disk cache, but it is worth it on my system at least.

This commit adds two command-line options to implement the changes
described above; -I ("--incremental") turns of "make mrproper" and -P
("--per-board-out-dir") creats a build directory per board rather than per
thread.

Tested:

    ./tools/buildman/buildman.py tegra
    ./tools/buildman/buildman.py -I -P tegra
    ./tools/buildman/buildman.py -b tegra_dev tegra
    ./tools/buildman/buildman.py -b tegra_dev -I -P tegra

... each once after deleting the buildman result/work directory, and once
"incrementally" after a previous identical invocation.

40 bits: pca9505, pca9698
"

To install just the SPL on i.MX6 board, perform the following operation
 $ dd if=SPL of=/dev/sdX seek=2 bs=512
To install the U-Boot image, copy u-boot.img to the first partition of
the SD/MMC/SATA drive. The partition must be formated to extfs.
