tnx, pushed to master. but, crap, it doesn't work :(...see inline comments: > Signed-off-by: Stephan Linz <l...@li-pro.net> > --- > platforms/x-load.in | 51 ++++++++++++++++++++++++++++++ > rules/x-load.make | 85 > +++++++++++++++++++++++++++++++++++++++++++++++++++ > 2 files changed, 136 insertions(+), 0 deletions(-) > create mode 100644 platforms/x-load.in > create mode 100644 rules/x-load.make > > diff --git a/platforms/x-load.in b/platforms/x-load.in > new file mode 100644 > index 0000000..b6840a1 > --- /dev/null > +++ b/platforms/x-load.in > @@ -0,0 +1,51 @@ > +## SECTION=bootloader > + > +menuconfig X_LOAD > + bool > + depends on ARCH_ARM_OMAP > + prompt "x-loader " > + help > + The X-Loader is a first level bootloader for Texas Intruments OMAP > + microprocessors (similar to the AT91Bootstrap application).

I'm not sure why it does this, looks like a bug. It should be fixed, but that requires some time and testing... However I can work around this limitation by changing _MAKE_OPT to _MAKE_ENV.
