Hello,
AXM is currently the only board failing 'buildman arm aarch64':
+arm-unknown-linux-gnueabi-ld.bfd: SPL image too big +make[2]: *** [spl/u-boot-spl] Error 1 +make[1]: *** [spl/u-boot-spl] Error 2 +make: *** [sub-make] Error 2
Apparently SPL is already being built in Thumb instruction set, so no way to gain anything that way.
I know, it was tricky to get SPL into 4k ...
What else can we do to get SPL size back under limit?
Hmm.. what is your exact toolchain?
I tested with the buildman-fetched gcc, -v gives 'gcc version 4.9.0 (GCC)'.
I've deleted the toolchain and re-fetched it again through buildman in case there was an issue with the install, and am getting the same result.
I've also tested with the latest ARM gcc package available with Ubuntu, that is, 'gcc version 5.2.1 20151010 (Ubuntu 5.2.1-22ubuntu1)', again with the same result.
I see for the axm board:
With eldk-5.4 pollux:u-boot-smartweb hs [master] $ arm-linux-gnueabi-size u-boot text data bss dec hex filename 212583 23792 23552 259927 3f757 u-boot pollux:u-boot-smartweb hs [master] $ arm-linux-gnueabi-size spl/u-boot-spl text data bss dec hex filename 14568 1212 1140 16920 4218 spl/u-boot-spl pollux:u-boot-smartweb hs [master] $
Confirmed right now that with eldk 5.4's gcc 4.7.2 axm builds fine.
With eldk-5.5 pollux:u-boot-smartweb hs [master] $ arm-linux-gnueabi-size u-boot text data bss dec hex filename 210690 23672 23556 257918 3ef7e u-boot pollux:u-boot-smartweb hs [master] $ arm-linux-gnueabi-size spl/u-boot-spl text data bss dec hex filename 14472 1212 1140 16824 41b8 spl/u-boot-spl pollux:u-boot-smartweb hs [master] $
Confirmed right now that with eldk 5.5's (or 5.5.3's) gcc 4.8.1 axm builds fine.
The issue appears with gcc 4.9 and 5.2.1 (and I suspect any version between 4.9 and 5.2.1 and beyond 5.2.1)
