drive an integrated RGB display output, or be used by some other display
controller such as HDMI. For this reason the DC node itself is not

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.

The pca953x chips are used as I2C I/O expanders.
This driver is designed to support the following chips:
"

         tca6416
24 bits: tca6424
40 bits: pca9505, pca9698
"
But for now this driver only supports max 24 bits and pca953x compatible
chips. pca957x compatible chips are not supported now.

ARM: mx6: Enable MMC and SATA extfs boot support

Enable support for booting U-Boot image from ext filesystem when either
SD/MMC or SATA support is compiled into the SPL. This will allow easy
transition from loading U-Boot image from ad-hoc offset on the card to
loading U-Boot image from the filesystem. VFAT support is intently not
enabled. The boot order is tweaked so that raw is tested first and if
the raw has no signature, FS boot is attempted.

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.

When defined, SPL will proceed to another boot method
if the image it has loaded does not have a signature.
This is useful if the subsequent boot methods are much
more complex.

(at least in Rev. B of the i.MX 7Dual Reference Manual). However,
when looking at the tables of other input selects, it is very natural
that there must be an input select for the UART2_TX_DATA_ALT0 pad.

it was required to set that particular input select register to get a
working UART2.
