Well, my small contribution is verifying address in license header found in new files. I'd like to invite Wolfgang into discussion to get his opinion about the topic. Well, I do not feel myself as a lawer to allege that removing address info from the license notice is ok. Has it already been discussed in the mailing list? >> * removed clean and distclean targets from board makefile >> * do not set machine id explicitly, if CONFIG_MACH_TYPE is defined >> * minor indentation cleanups >> >> board/timll/devkit3250/Makefile | 44 +++++++++++++ >> board/timll/devkit3250/devkit3250.c | 71 ++++++++++++++++++++ >> boards.cfg | 3 +- >> include/configs/devkit3250.h | 121 +++++++++++++++++++++++++++++++++++ >> 4 files changed, 238 insertions(+), 1 deletions(-) >> create mode 100644 board/timll/devkit3250/Makefile >> create mode 100644 board/timll/devkit3250/devkit3250.c >> create mode 100644 include/configs/devkit3250.h >> [snip]

Nice!

Thanks, that is fare enough! I want to make sure you understand, that having the right address in the license statement is not a blocker. > > I'd like to invite Wolfgang into discussion to get his opinion about the topic. Well, I do not feel myself as a lawer to allege that removing address info from the license notice is ok. Has it already been discussed in the mailing list? Actually, you don't have to be a lawyer to verify if there is a requirement to have the postal address (that changes from time to time) in the license statement. AFAIK, there is no such requirement and the fact that huge amount of files has a wrong postal address just emphasizes this. What I'm proposing here is a way to spare the effort of changing the postal address in the future. And if no one cares for the right address, then why bother writing it in the source code? To make the source code larger? And yes of course, I would like to here what Wolfgang has to say about this. > >>> * removed clean and distclean targets from board makefile >>> * do not set machine id explicitly, if CONFIG_MACH_TYPE is defined >>> * minor indentation cleanups >>> >>> board/timll/devkit3250/Makefile | 44 +++++++++++++ >>> board/timll/devkit3250/devkit3250.c | 71 ++++++++++++++++++++ >>> boards.cfg | 3 +- >>> include/configs/devkit3250.h | 121 +++++++++++++++++++++++++++++++++++ >>> 4 files changed, 238 insertions(+), 1 deletions(-) >>> create mode 100644 board/timll/devkit3250/Makefile >>> create mode 100644 board/timll/devkit3250/devkit3250.c >>> create mode 100644 include/configs/devkit3250.h >>> > > [snip] >

This change adds a basic support for Embest/Timll DevKit3250 board, NOR and UART are the only supported peripherals for a moment. The board doesn't require low-level init, because the initial SDRAM and GPIO configuration is performed during kickstart bootloader execution.
