| Subject: [PATCH] sunxi: allow 32-bit builds for 64-bit SoCs | |
| At the moment we build the SPL and U-Boot proper for the 64-bit AArch64 | |
| instruction set. But since the cores provide an AArch32 compatibility mode | |
| and in fact the BootROM runs in 32-bit mode, it can be useful to have at | |
| least the SPL run in AArch32 as well. This has two advantages: | |
| - As AArch32 features the compact Thumb2 instruction encoding, we can |
