[U-Boot] [PATCH v4 0/7] arm: vf610: Add Freescale Vybrid VF610 CPU and VF610TWR board support

[Alison Wang]

This series contain the support for Freescale Vybrid VF610 CPU and VF610TWR 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, VF610 is a dual-core eMPU combining the ARM
Cortex A5 and Cortex M4 cores.

VF610 shares some IPs with i.MX family, such as FEC,ESDHC,WATCHDOG,I2C,ASRC and ESAI.
VF610 also shares some IPs with ColdFire family, such as eDMA and DSPI.
VF610 still has its own IPs, such as PIT,SAI,UART,QSPI and DCU.

http://www.freescale.com/webapp/sps/site/homepage.jsp?code=VYBRID

To align with the description in the above documents, "VF610" is used as the SoC name instead of "MVF600".

The u-boot runs on Cortex A5 core.

Changes in v4:
- Rename "MVF600" to "VF610"
- Define PAD_CTL_PUS_47K_UP and PAD_CTL_PUS_100K_UP with PAD_CTL_PUE enabled
- Reorganize the definitions
- Correct the spaces and tabs
- Rename mvf_pins.h to iomux-vf610.h
- Add README.vf610 about fuse assignments for MAC addresses
- Rename directory name 'mvf600' to 'vf610'
- Rename directory 'arch-mvf600' to 'arch-vf610'
- Add Vybrid VF610 to mxc_ocotp document
- Rename directory name 'mvf600twr' to 'vf610twr'
- Rename mvf600twr.h to vf610twr.h
- Use NEW_PAD_CTRL instead of MUX_PAD_CTRL
- Remove CONFIG_ETHPRIME option
- Add CONFIG_CMD_MEMSET option

Changes in v3:
- Rename the common functions and enums
- Move the structure definitions to imx-regs.h
- Define PAD_CTL_PUE with PKE enabled
- Remove the changes for FEC_RCNTRL_RGMII / FEC_RCNTRL_RMII / FEC_RCNTRL_MII_MODE bits, as they are already set in fec_reg_setup()
- Replace BOOT_FROM by BOOT_OFFSET
- Enable CONFIG_OF_LIBFDT option
- Add useful define instead of raw number
- Use clrsetbits_le32 to set the single bits
- Move setup_iomux_enet() to board_early_init_f and remove board_eth_init()
- Remove redundant define
- Move CONFIG_IOMUX_SHARE_CONF_REG 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'
- 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
