* x86: ns16550: Rework driver to allow for x86 I/O spaceMichel Stam2014-04-092-35/+0
| | | | | | | | | | | | The current implementation fakes a memory-mapped I/O device at 0x3f8 and 0x2f8, then uses platform read/write functions to do the actual reading and writing. These platform functions only exist for the x86 platform; better to move the I/O routines into the driver and have the driver request I/O ports using request_ioport_region.

* Remove bad Kconfig reference to HAS_PCIAlexander Shiyan2012-12-081-1/+0
| | | | | | | Barebox not contain symbol HAS_PCI, so remove all references to it. Signed-off-by: Alexander Shiyan <shc_work@mail.ru> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* Cleanup Kconfig filesAlexander Shiyan2012-12-081-1/+1
| | | | | | | | | This patch provides a global cleanup barebox Kconfig files. This includes replacing spaces to tabs, formatting in accordance format, removing extraneous lines and spaces. No functional changes. Signed-off-by: Alexander Shiyan <shc_work@mail.ru> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* Treewide: remove address of the Free Software FoundationSascha Hauer2012-09-174-16/+0
| | | | | | | The FSF address has changed in the past. Instead of updating it each time the address changes, just drop it completely treewide. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* introduce io.hSascha Hauer2011-09-222-2/+2
| | | | | | | To allow for some generic io accessors introduce io.h and use this instead of asm/io.h throughout the tree. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* Bring in the time reference for the x86 platformsJuergen Beisert2010-01-142-0/+74
| | | | | | | | This code uses the always (hopefully) existing PIT device to get the time reference for barebox. Signed-off-by: Juergen Beisert <jbe@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* Bring in the first x86 specific codeJuergen Beisert2010-01-144-0/+103
Add some generic required code to make barebox work on x86. Note: Resetting the CPU is unfinished yet. I need some ideas how to reset this kind of architecture gracefully. Signed-off-by: Juergen Beisert <jbe@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
