Subject: [PATCH v2 1/9] ARM: dts: imx7d-pico: Do not harcode the memory size

From: Fabio Estevam <festevam@...il.com>

Currently the memory size described in dts is 2GB, which is incorrect.

There are 512MB and 1GB versions of imx7d-pico boards, so remove
the hardcoded memory size and let the bootloader pass the correct
value to the kernel.
