Cover letter [U-Boot] [RFC PATCH 00/10] sunxi: Allwinner A64 SPL support
Quoted 10 lines · Andre Przywara
Hi,
this is my first take on the SPL support for the Allwinner A64 SoC. The actual meat - the DRAM initialization code - has been provided by Jens - many thanks for that!
The rest of the patches mostly deal with the 32-bit/64-bit switch.While it is possible and seems natural to let the SPL also run in 64-bit, this creates a really large binary (32600 Bytes in my case). With some hacks (plus some fixes to make the SPL 64-bit safe) I got this to work,
So how about we merge the 64bit version first (since that's *way* easier to compile for everyone) and then consider the move to 32bit afterwards? I don't even want to start to imagine how to squeeze a 32bit SPL build into the build process for our U-Boot binaries.

but any addition will probably break it and exceed the 32KB limit that the BROM imposes. Debug is the first obvious victim here.
Do you have some section size comparisons between the two?
