Chris Spencer reports that when enabling ext4 read support without
also enabling write support the following error is seen:

fs/fs.c:198:12: error: 'ext4_write_file' undeclared here (not in a
function); did you mean 'ext4_read_file'?
   .write = ext4_write_file,
            ^~~~~~~~~~~~~~~
Fix this problem by moving these options to Kconfig.

Change CONFIG_ENV_OFFSET for Poplar to be 1MB further into the eMMC
than before.  This puts it immediately prior to the space we are
reserving offset 0x200000-0x400000 for UEFI to save its persistent
data.  Define CONFIG_ENV_SIZE as a product of env_mmc_nblks and the
sector size, like CONFIG_ENV_OFFSET is.

Fixes for 2019.01

Check the size of the generated u-boot.imx file. Report an error
if it would be too big and overwrite the u-boot environment.

Remove unused Android partitions:
  - efs, crypto, cache: we don't use it anymore (images are not built
    in AOSP
  - ipu1, ipu2: IPU firmware is now a part of vendor image and doesn't
    reside as a separate partition

While at it, rename "reserved" partition to "uboot-env", as it's
actually stores U-Boot environment.

pinctrl_decode_pin_config_dm() is basically a feature-equivalent
implementation of pinctrl_decode_pin_config(), which operates
on struct udevice devices and uses the dev_read_*() API.

imx for 2019.01

- introduce support for i.MX8M
- fix size limit for Vhybrid / pico boards
- several board fixes
- w1 driver for MX2x / MX5x

U-Boot binary has grown in such a way that it goes beyond the reserved
area for the environment variables.

Running "saveenv" causes U-Boot to hang because of this overlap.

Fix this problem by increasing the CONFIG_ENV_OFFSET size.

Also, in order to prevent this same problem in the future, use
CONFIG_BOARD_SIZE_LIMIT, which will detect the overlap in build-time.

CONFIG_BOARD_SIZE_LIMIT does not accept math expressions, so declare
CONFIG_ENV_OFFSET with its direct value instead.
