From 9eea50162c6a9bbdd01736984fc939649119f382 Mon Sep 17 00:00:00 2001 From: Andy Yan Date: Mon, 24 Jul 2017 17:49:01 +0800 Subject: [PATCH] microblaze: spl: configure SYS_MALLOC_F_LEN independently for SPL and full U-Boot Some platforms have very limited SRAM to run SPL code, so there may not be the same amount space for a malloc pool before relocation in the SPL stage as the normal U-Boot stage. Make SPL and (the full) U-Boot stage use independent SYS_MALLOC_F_LEN, so the size of pre-relocation malloc pool can be configured memory space independently.
