[U-Boot] OMAP4: Broken SPL generation

Building the SPL for omap4_sdp4430 and omap4_panda in recent mainline 
is broken due to a resulting image size > 32k:

Configuring for omap4_sdp4430 board...
arm-none-linux-gnueabi-ld: u-boot-spl section .rodata will not fit in 
region .sram
arm-none-linux-gnueabi-ld: region .sram overflowed by 612 bytes

Configuring for omap4_panda board...
arm-none-linux-gnueabi-ld: u-boot-spl section .rodata will not fit in 
region .sram
arm-none-linux-gnueabi-ld: region .sram overflowed by 620 bytes

This seems to come from the the patch "omap: add MMC and FAT support 
to SPL" [1] adding a lot of code to the SPL.

Does anybody have a quick solution for this fixing the build of these 
boards for the -rc cycle? Else I'm about to send a patch like [2] 
disabling the SPL build until a patch to reduce the image size is 
available.

Best regards

Dirk
