Hi Walter, > Subject: [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.
Do you have some data that how much is decreased using OF_PLATDATA?
