From 2d8f831fb2b0a03561e6732b25191c9d062005af Mon Sep 17 00:00:00 2001 From: Antonio Nino Diaz Date: Wed, 13 Jun 2018 13:34:46 +0100 Subject: [PATCH] rpi3: Fix kernel boot documentation The order of the arguments of memmap was swapped. The old command was reserving 256 MiB from the 16 MiB barrier, it should be reserving only 16 MiB at the 256 MiB barrier. It worked because the memory used by the Trusted Firmware was reserved anyway.
