[PATCH v2 3/6] fdt: Add fdtdec functions to read byte array

[Simon Glass]

From: Anton Staff <robotboy@chromium.org>

Sometimes we don't need a full cell for each value. This provides
a simple function to read a byte array, both with and without
copying it.

Changes in v2:
- Use correct name for get_prop_check_min_len() function
