From cfe77beea4bb2ec501a14ab822e4773f64dfb21b Mon Sep 17 00:00:00 2001 From: Gabe Black Date: Wed, 19 Jun 2013 04:54:38 -0700 Subject: libpayload: Make the region to scan for the cb tables configurable. The address range to scan for the coreboot tables varies from machine to machine based on the range memory occupies on the SOC being booted and on the amount of memory installed on the machine. To make libpayload work on different ARM systems with different needs, this change makes the region to scan configurable. In the future, we might want to come up with a more automatic mechanism like on x86, although there's less consistency on ARM as far as what ranges are even memory in the first place.
