From b77431336e44ba9721f18220e2a7dedafe250528 Mon Sep 17 00:00:00 2001 From: David Hendricks Date: Fri, 9 Aug 2013 18:19:29 -0700 Subject: exynos5420: get rid of old exynos5420_config_l2_cache() We set up L2 cache early in romstage now so the old function is now redundant.

The lzma decoding function in the RAM stage allocates nearly 16KB on the stack which is shared between the bootblock, rom stage, and ram stage. The stack had been much too small and needed to be expanded.
