please don't split this in the middle of ARRAY_SIZE(, put thoe whole
ARRAY_SIZE on new line and indent below the gpio_led_pads. Fix globally.

This error message is useless, either reword it or remove it.

Use BIT(n) instead of (1 << n), in a macro.

Implement empty setup_usb() for case where CONFIG_USB_EHCI_MX6 is not
set and remove this check here since setup_usb() will always be defined.

Do not apply bitwise operations on signed integer values , just check
one after the other and fail with a meaningful error message.

Drop this fatload stuff, just use 'load' command and autodetect FS.
Avoid fat altogether if possible.

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

  To: u-boot

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 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

Darn, minor nit, should be TARGET_SAMTEC_VINING_2000 (for consistency
with VINING_FPGA).

Looking at this, doesn't pwm_init() / pwm_config() return a valid error
code ? If so, propagate it out of this function instead of always
returning -EINVAL .

ret is signed integer, so use %i m not %0x

If you provide ret value above, provide it here as well. You can even
move this print to failpath.

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
