after update from git with include-files patch i reworked
my patch together with advices from Russell King.
Please check for correctness.
Would you mind to comment on the attached patch please ??
Thank you very much.
(Its Russell King who advice me to as for comments here)
The trizeps4_pcmcia.diff contains the PCMCIA support for trizeps modules
