Re: [ptxdist] Binary patches

["Matthias Klein" <matthias.klein@optimeas.de>]

Hi Andreas,

my intension is to create a patch file (containing the firmware) which 
will be applied at the kernel.prepare step using the series file.
(Then at the kernel.compile step the firmware should be compiled into 
the kernel.)


Best regards,

Matthias
