[U-Boot] [PATCH v2 0/6] arm: mvf600: Add Freescale Vybrid MVF600 CPU and MVF600TWR board support

[Alison Wang]

This series contain the support for Freescale Vybrid MVF600 CPU and MVF600TWR board.

Vybird devices are built on an asymmetrical-multiprocessing architecture
using ARM cores. The families in the Vybrid portfolio span entry-level,
single core Cortex-A class SoCs all the way to dual heterogeneous core SoCs
with multiple communication and connectivity options.

Part of the Vybrid platform, MVF600 is a dual-core eMPU combining the ARM
Cortex A5 and Cortex M4 cores.

The u-boot runs on Cortex A5 core.

MVF600 shares some IPs with i.MX family, such as FEC,ESDHC,WATCHDOG,I2C,ASRC and ESAI.
MVF600 also shares some IPs with ColdFire family, such as eDMA and DSPI.
MVF600 still has its own IPs, such as PIT,SAI,UART,QSPI and DCU.

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 name 'arch-vybrid' to 'arch-mvf600'
- Use common iomux-v3 code
- Use common FEC driver fec_mxc.c
- Add watchdog support
- Add an entry to MAINTAINERS file
- Rename directory name 'vybird' to 'mvf600twr'
- Use standard method to set gd->ram_size
- Rewrite board_mmc_getcd() function
- Remove useless undef
- Remove hardcoded IP addresses and MAC addresses
- Move CONFIG_MACH_TYPE to board configuration file
