[U-Boot] [PATCH v6] mx6sx: Add initial support for Samtec VIN|ING 2000 board

This patch adds initial support for Samtec VIN|ING 2000 board.

Signed-off-by: Christoph Fritz chf.fritz@googlemail.com --- Changes since v1: - add more comments (enet phy init) - fix layout style e.g. multi-line-comments - use pinmux macros - use helper funcs clrsetbits_le32() and wait_for_bit() - make some functions static - drop board_ehci_hcd_init() and board_phy_config() - simplify environment Changes since v2: - adapt error handling in board_eth_init() and read_adc() - purge unused macros - use config_distro_bootcmd as environment - fix CONFIG_PWM_IMX undef handling Changes since v3: - fix comment spelling - use u32 - rearrange if condition Changes since v4: - use parent error codes - rename config string to TARGET_SAMTEC_VINING_2000 Changes since v5: - simplify board_eth_init() error message
