00caae6d47 env: Rename getenv/_f() to env_get()
We are now using an env_ prefix for environment functions. Rename these
two functions for consistency. Also add function comments in common.h.

Quite a few places use getenv() in a condition context, provoking a
warning from checkpatch. These are fixed up in this patch also.

00bbe96eba arm: omap: Unify get_device_type() function
Refactor OMAP3/4/5 code so that we have only one get_device_type()
function for all platforms.

Details:
 - Add ctrl variable for AM33xx and OMAP3 platforms (like it's done for
   OMAP4/5), so we can obtain status register in common way
 - For now ctrl structure for AM33xx/OMAP3 contains only status register
   address
 - Run hw_data_init() in order to assign ctrl to proper structure
 - Remove DEVICE_MASK and DEVICE_GP definitions as they are not used
   (DEVICE_TYPE_MASK and GP_DEVICE are used instead)
 - Guard structs in omap_common.h with #ifdefs, because otherwise
   including omap_common.h on non-omap4/5 board files breaks compilation

Buildman script was run for all OMAP boards. Result output:
    arm: (for 38/616 boards)
        all +352.5
        bss -1.4
        data +3.5

        spl/u-boot-spl:text +30.5

    (no errors to report)

1a9a5f7a39 usb: host: xhci-omap: fix double weak board_usb_init functions
A weak version of the function board_usb_init is implemented in:
common/usb.c
drivers/usb/host/xhci-omap.c

To fix the double implementations:
* Convert the board_usb_init function in drivers/usb/host/xhci-omap.c
  normal (not weak).
* The function board_usb_init in drivers/usb/host/xhci-omap.c calls to
  the weak function omap_xhci_board_usb_init.
* Rename board version of the function board_usb_init to
  omap_xhci_board_usb_init.
  Done only for boards that defines CONFIG_USB_XHCI_OMAP.

To achieve the same flexibility with the function board_usb_cleanup:
* Add a normal (not weak) implementation of the function
  board_usb_cleanup in drivers/usb/host/xhci-omap.c
* The function board_usb_cleanup in drivers/usb/host/xhci-omap.c calls
  to the weak function omap_xhci_board_usb_cleanup.
* Rename board version of the function board_usb_cleanup to
  omap_xhci_board_usb_cleanup.
  Done only for boards that defines CONFIG_USB_XHCI_OMAP.

e53ad4b445 board/ti/am43xx: add support for parallel NAND
This patch adds support for NAND device connected to GPMC chip-select on
following AM43xx EVM boards.

am437x-gp-evm: On this board, NAND Flash signals are muxed with eMMC, thus at a
  time either eMMC or NAND can be enabled. Selection between eMMC and NAND is
  controlled by:
  (a) Statically using Jumper on connecter (J89) present on board.
  (a) If Jumper on J89 is NOT used, then selection can be dynamically controlled
      by driving SPI2_CS0[MUX_MODE=GPIO] pin via software:
      SPI2_CS0 == 0: NAND (default)
      SPI2_CS0 == 1: eMMC

am43x-epos-evm: On this board, NAND Flash control lines are muxed with QSPI,
  Thus only one of the two can be used at a time. Selection is controlled by:
  (a) Dynamically driving following GPIO pin from software
      GPMC_A0(GPIO) == 0 NAND is selected (default)

NAND device (MT29F4G08AB) on these boards has:
 - data-width=8bits
 - blocksize=256KB
 - pagesize=4KB
 - oobsize=224 bytes
For above NAND device, ROM code expects the boot-loader to be flashed in BCH16
ECC scheme for NAND boot, So by default BCH16 ECC is enabled for AM43xx EVMs.

0df8afdf10 ARM: AM43xx: Enable DDR dynamic IO power down for DDR3
This patch enables dynamically powering down the
IO receiver when not performing a read on DDR3 board.
This optimizes both active and standby power consumption.
This is derived from a patch that is done on AM335x[1]
