[U-Boot] [PATCH 5/6] PXA: Cleanup serial_pxa
Marek Vasut
marek.vasut at gmail.com
Sun Aug 28 03:42:16 CEST 2011
* Cleanup register definitions by introducing new regs-uart.h, compliant with
rest of U-Boot.
* Remove old register definitions from pxa-regs.h
* Convert serial_pxa to new regs-uart.h
* Cleanup serial_pxa
