From f1896c45cb2f7d8dbed27e784a6459a129fc0762 Mon Sep 17 00:00:00 2001 From: Andy Yan Date: Mon, 24 Jul 2017 17:43:34 +0800 Subject: spl: make SPL and normal u-boot stage use independent SYS_MALLOC_F_LEN 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.
