Subject: Reduce the runtime stack size in BL stages.
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=aa442d3461d5cdb35febcfe5d89a67ae31207b60;p=project%2Fbcm63xx%2Fatf.git

Reduce the runtime stack size in BL stages.

This patch separates the stack size for each BL stage and
reduces it after stack usage analysis was done.

Fixes ARM-software/tf-issues#200
