When binutils > 2.28 are selected on Arm Cortex-M cpu,
linux kernel does not boot due to a new implementation
of 'adr pseudo instruction' on binutils.

The logic is inverted here: it should be
depends on BR2_ARMV7M
depends on !BR2_BINUTILS_VERSION_2_28_X
I guess you didn't test it?
After, new test:
$> grep BINUTILS_VERSION_2_29 .config
BR2_BINUTILS_VERSION_2_29_X=y
The depends must be
depends on !BR2_ARMV7M
depends on !BR2_BINUTILS_VERSION_2_28_X
I will update the patch.
