This patch adds generic codes to support Freescale's Vybrid MVF600 CPU.

It aligns Vybrid MVF600 platform with i.MX platform. As there are some differences between MVF600 and i.MX platforms, the specific codes are in the arch/arm/cpu/armv7/mvf600 directory.

Signed-off-by: Alison Wang b18965@freescale.com --- Changes in v3: - Rename the common functions and enums - Move the structure definitions to imx-regs.h

Changes in v2: - Remove vybrid-common directory - Rename directory name 'vybrid' to 'mvf600' - Add generic.c file - Rewrite get_reset_cause() to make it readable - Remove reset_cpu(), and use the function in imx_watchdog.c - Rewrite timer.c file - Use vybrid_get_clock(VYBRID_UART_CLK) instead of vybrid_get_uartclk() - Remove lowlevel_init.S, and add clock_init() in board_early_init_f() - Remove useless CONFIG_SYS_ defines - Move CONFIG_MACH_TYPE to board configuration file - Define C structures and access C structures to set/read registers - Remove useless errata - Remove useless macros - Rename directory 'arch-vybrid' to 'arch-mvf600'
