Were you able to get this to compile and fit in the SRAM?

With the latest U-Boot and your patch I get the following on compile:
arm-poky-linux-gnueabi-ld.bfd: u-boot-spl section `.rodata' will not fit in region `.sram'
arm-poky-linux-gnueabi-ld.bfd: region `.sram' overflowed by 9928 bytes
scripts/Makefile.spl:333: recipe for target 'spl/u-boot-spl' failed
make[1]: *** [spl/u-boot-spl] Error 1
Makefile:1382: recipe for target 'spl/u-boot-spl' failed
make: *** [spl/u-boot-spl] Error 2

I had to remove some of the other features to get it to fit in SRAM.

Here is the patch that I sent yesterday:
