4 years agobuildman: Add an option to ignore device-tree warnings
Simon Glass [Thu, 9 Apr 2020 21:08:52 +0000 (15:08 -0600)]
buildman: Add an option to ignore device-tree warnings

Unfortunately the plague of device-tree warnings has not lifted. These
warnings infiltrate almost every build, adding noise and confusion.

Add a buildman option to ignore them. This option works only with the
summary option (-s). It does not affect the build process.

4 years agobuildman: Make -I the default
Simon Glass [Thu, 9 Apr 2020 21:08:51 +0000 (15:08 -0600)]
buildman: Make -I the default

At present buildman defaults to running 'mrproper' on every thread before
it starts building commits for each board. This can add a delay of about 5
seconds to the start of the process, since the tools and other invariants
must be rebuilt.

In particular, a build without '-b', to build current source, runs much
slower without -I, since any existing build is removed, thus losing the
possibility of an incremental build.

Partly this behaviour was to avoid strange build-system problems caused by
running 'make defconfig' for one board and then one with a different
architecture. But these problems were fixed quite a while ago.

The -I option (which disabled mrproper) was introduced four years ago and
does not seem to cause any problems with builds.

So make -I the default and deprecate the option. To allow use of
'mrproper', add a new -m flag.

dts: imx: Add fixed-link property to HSC and DDC (imx53) devices

Those two boards are supposed to be run with a single u-boot binary.
There are notable differences though - HSC uses DSA switch (which
phy_id == 0x0) and DCC (DP83848C).

After the commit 3bf135b6c367
("drivers: net: phy: Ignore PHY ID 0 during PHY probing") the PHY devices
with phy_id == 0 are not created in U-Boot anymore. This caused regression
on HSC.

To fix this problem - the fec's 'fixed-link' node has been introduced and
the phy_id is not assessed anymore. This approach works on both boards.
