With this rebase I''ve picked up some patches from Julien which were required to do things properly, so the gic v7 and device blacklisting patches have been changed to use the proper mechanisms.

Since OMAP UART has a few distinct features than common 8250 UART, I re-implemented its driver rather than porting it based on ns16550.c. There are mainly two big differences between the implementations. First, OMAP UART introduces the concept of register access mode, which divides the register map into seperated...

This is a fairly standard and old machine with 2 COM ports. Recently (last Friday) I decided to update my RELENG_7 system and also to transition from sio to uart.

The current early-printk support for ARM is rather hard-coded, making it hard to add machines or tweak settings. This series slightly moves some code to gather UART settings in xen/arch/arm/Rules.mk instead of the actual .c files. Also it allows two different machines with different settings to share the same driver, which the last patch exploits to add support the Calxeda Midway hardware. This haven''t been extensively tested, but I looked at the gen...

We are in the process of migrating one of our embedded apps to use uart by default instead of sio in RELENG_7 in prep for the day when sio eventually disappears. Unfortunately, the application doesnt want to work with uart with puc backed devices, but still works with sio. Stranger still, the app works with the uart driver when uart attaches to the built in com po...

Hi Geert Thanks for your help. What I'm planning to do is to write COM32 image that will open UART channel and wait for input (until timeout arrives). In case input arrives, it will parse and validate it and act accordingly. My solution doesn't involve user interaction. I've searched the page you've sent me and it talks about serial console and I'm not sure I can use it for my...

Hi, I'm having issues connecting Garmin GPS 18 to COM1 on 9.1, I get nothing but silence. Identical setup works absolutely fine with Linux. I've got PPS wire connected to DCD, but that seems to make no difference on Linux, so I presume it shouldn't affect fbsd either. On Linux, I get: $ uname -a Linux ubuntu 3.8.0-19-generic #29-Ubuntu SMP Wed Apr 17 18:16:28 UTC 2013 x86_64 x86_64
