[PATCH v2 0/6] mx6cuboxi: enable OF_PLATDATA with MMC support

The SPL in iMX6 boards is restricted to 68 KB as this is the free available
space in OCRAM for most revisions. In this context, adding OF_CONTROL and DM
increases the SPL size which could make it difficult to add specific features
required for custom scenarios.

These patches aim to take advantage of OF_PLATADATA in order to reduce the SPL
size in this scenario, by parsing DT data to generate platdata structures,
and thus removing the overhead caused by DT and related libraries.

This series is focused in MMC driver, which is used for boot in boards such as
Cubox-i. Also, in order to support CD, the OF_PLATDATA support is also
implemented on GPIO driver.

Changes in v2:
- Improve commit message with footprint reduction

Walter Lozano (6):
  mmc: fsl_esdhc_imx: rename driver name to match ll_entry
  mmc: fsl_esdhc_imx: add OF_PLATDATA support
  gpio: mxc_gpio: add OF_PLATDATA support
  mmc: fsl_esdhc_imx: add CD support when OF_PLATDATA is enabled
  drivers: rename more drivers to match compatible string
  mx6cuboxi: enable OF_PLATDATA
