From 1a83fb4a17d959d7b037999ab7ed7e62429abe34 Mon Sep 17 00:00:00 2001 From: Siarhei Siamashka Date: Tue, 31 May 2016 01:48:06 +0300 Subject: [PATCH] sunxi: Move the SPL stack top to 0x1A000 on Allwinner A64/A80 Since the SRAM C corruption issue is now resolved on Allwinner A64, it is possible to move the stack top to the address 0x1A000 on both A64 and A80. The boot ROM can load SPL binaries with up to 32 KiB size on A64 (the 24 KiB SPL size limitation only affects A10/A20), and this patch also ensures the availability of 8 KiB stack.
