Mon Oct 17 20:00:06 CEST 2011
This change adds initial support for NXP LPC32x0 SoC series.
Signed-off-by: Vladimir Zapolskiy <vz at mleia.com>
---
Changes from v1:
* BIT(n) and SBF(s, v) macro are not used anymore
* removed NS16550 and 14-clock UART definitions from uart.h
* added devices.c file, which contains standard UART preinitialization routine
* added get_serial_clock() function, it returns actual frequency of UART clock
* __udelay() realization is simplified, no need of interrupt handling
